[0010] Incidentally, the program for realizing the software appearing in this embodiment may be provided as a non-transitory computer-readable recording medium, or may be provided so as to be downloadable from an external server, or may be provided so that the program is started on an external computer and its functions are realized on a client terminal (so-called cloud computing).

[0011] In addition, in this embodiment, the term "unit" may include, for example, a combination of hardware resources implemented by a circuit in the broad sense and software information processing that can be specifically realized by these hardware resources. In addition, in this embodiment, various information is handled, and this information is represented, for example, by physical values ​​of signal values ​​representing voltage and current, high and low signal values ​​as a binary bit group consisting of 0 or 1, or quantum superposition (so-called quantum bits), and communication and calculation can be performed on the circuit in the broad sense.

[0012] In addition, a circuit in the broad sense is a circuit realized by at least appropriately combining a circuit, circuitry, a processor, a memory, etc. In other words, it includes an application specific integrated circuit (ASIC), a programmable logic device (e.g., a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA)), etc.

[0013] <Embodiment 1> 1. System Configuration The system configuration according to the first embodiment will be described below. Fig. 1 is a diagram showing an example of the overall configuration of a summary creation system 1. Fig. 1 shows an overview of each device provided in the summary creation system 1 and users who use those devices. Each overview will be explained from time to time with reference to other figures. The summary creation system 1 is an information processing system that executes a summary creation process that analyzes numerical trends and the factors that caused the trends to appear from a group of numerical data, and creates a document (hereinafter referred to as a "summary") that summarizes the main points of the analysis results.

[0014] The summary creation system 1 includes a communication line 2, a server device 10, and a user terminal 20. The communication line 2 is not particularly limited, but may be configured, for example, by the Internet network. The communication line 2 may also include a local area network, a mobile communication network, and a VPN (Virtual Private Network), etc. The communication line 2 mediates data exchange between devices connected to the line. In the example of FIG. 1, the server device 10 is connected to the communication line 2 by wire, and the user terminal 20 is connected wirelessly. The connection of each device to the communication line 2 may be wired or wireless.

[0015] The server device 10 is an information processing device that executes summary creation processing. The server device 10 stores a journal entry database DB1 and a financial database DB2. The journal entry database DB1 stores journal entry data, i.e., data that is organized to be useful for creating ledgers and financial statements, including information on transactions and economic activities. The financial database DB2 stores financial data organized based on the journal entry data, i.e., data that shows information on the financial status and economic activities of a company or organization (including financial statements such as balance sheets and profit and loss statements).

[0016] The server device 10 also includes a summary creation AI module 110, a trend determination AI module 120, and a factor determination AI module 130 (hereinafter, when there is no need to distinguish between them, they are referred to as "AI modules 100"). The AI ​​modules 100 are modules that are adjusted (tuned) to realize predetermined functions using AI (Artificial Intelligence) technology.

[0017] The AI ​​module 100 has a natural language processing model with improved accuracy through machine learning using a large-scale data set called LLM (Large Language Models), and realizes a sentence generation function capable of generating natural sentences. The summary creation AI module 110 is adjusted to realize a summary creation function that creates a summary that summarizes the numerical trend and the factors of the trend when the numerical trend and the factors of the trend indicated by the numerical data group are input.

[0018] The trend determination AI module 120 is adjusted to realize not only a text generation function but also a trend analysis function that, when a group of numerical data is input, analyzes the trend of the numerical values ​​indicated by the group of numerical data. The factor determination AI module 130 is adjusted to realize not only a text generation function but also a factor analysis function that, when a group of numerical data and the trend of the numerical values ​​indicated by the group of numerical data are input, analyzes the parts of the group of numerical data that are the factors of the trend. These analysis functions are realized, for example, by performing learning based on a group of data related to a statistical analysis method (such as text explaining the statistical analysis method and sample data).

[0019] The user terminal 20 is a terminal used by a user, such as a smartphone, a tablet terminal, or a personal computer. The user terminal 20 executes display of images in the summary creation process and acceptance of operations by the user. The server device 10 executes a display process for displaying images on the user terminal 20 and an authentication process for authenticating the user of the user terminal 20.

[0020] The server device 10 performs, for example, processing such as generating and transmitting an HTML (Hyper Text Markup Language) file as display processing, and displays a web page showing a system screen on the user terminal 20. Note that an application program for using the summary creation system 1 may be installed in the user terminal 20, and the server device 10 may perform processing such as generating and transmitting display data in the application as display processing.

[0021] 2.

The at least one processor may be configured, for example, by a central processing unit (CPU), a micro processing unit (MPU), a graphics processing unit (GPU), one or more integrated circuits, one or more discrete circuits, or a combination of these (not shown).

[0023] The control unit 11 is a computer that realizes various functions related to the summary creation system 1 by reading out a predetermined program stored in the storage unit 12. That is, information processing by software stored in the storage unit 12 is specifically realized by the control unit 11, which is an example of hardware, and can be executed as each functional unit included in the control unit 11. Note that the control unit 11 is not limited to being single, and may be implemented with multiple control units 11 for each function. Also, a combination of these may be used.

[0024] (Storage unit 12) The storage unit 12 stores various information defined by the above description. This can be implemented, for example, as a storage device such as a solid state drive (SSD) or a hard disk drive (HDD) that stores various programs and the like related to the summary creation system 1 executed by the control unit 11, or as a memory such as a random access memory (RAM) that stores temporarily required information (arguments, arrays, etc.) related to the program's calculations. The storage unit 12 stores various programs, variables, etc. related to the summary creation system 1 executed by the control unit 11.

[0025] (Communications Department 13) The communication unit 13 is configured by a communication module. The communication module may be a wireless communication module conforming to standards such as IEEE802.11a / b / g / n / ac / ax, LTE, 5G, and 6G, or may be a wired communication module conforming to standards such as IEEE802.3. The communication unit 13 is configured to be capable of transmitting various electrical signals from the server device 10 to external components. The communication unit 13 is also configured to be capable of receiving various electrical signals from the external components to the server device 10. More preferably, the communication unit 13 has a network communication function, and may be implemented so that various information can be communicated between the server device 10 and an external device via the communication line 2.

[0026] Fig. 3 is a diagram showing an example of a hardware configuration of the user terminal 20. The user terminal 20 includes a control unit 21, a storage unit 22, a communication unit 23, an input unit 24, an output unit 25, and a bus 26. The bus 26 electrically connects the various units included in the user terminal 20. The control unit 21, the storage unit 22, and the communication unit 23 are similar hardware to the control unit 11, the storage unit 12, and the communication unit 13 shown in Fig. 2, although the specifications, model, etc. may be different.

[0027] (Input section 24) The input unit 24 has keys, buttons, a touch screen, a mouse, etc., and receives input from the user. The input unit 24 also has a microphone, and receives voice input from the user.

[0028] (Output section 25) The output unit 25 has a display, a speaker, and the like, and displays visual information generated in a manner that is visible to the user, such as screens, images, icons, text, and the like, on the display surface of the display, and outputs sounds including voice.

[0029] 3. Information Processing The summary creation process described above will be described below as an example of information processing according to the embodiment. In the following description, the server device 10 and the user terminal 20 are described as the subjects of each summary creation process, but the information processing is executed by a processor included in the control unit of each device.

[0030] Fig. 4 is an activity diagram showing an example of summary creation processing. The summary creation processing shown in Fig. 4 is started when a user of the user terminal 20 performs an operation to display a summary creation screen, which is a display screen for a summary creation service provided by the server device 10. First, the server device 10 generates screen data showing the summary creation screen at A11 and transmits the generated screen data to the user terminal 20. The user terminal 20 displays the summary creation screen shown by the transmitted screen data at A12.

[0031] Fig. 5 is a diagram showing an example of a displayed summary creation screen. In the example of Fig. 5, the server device 10 displays a summary creation screen C1 on the display surface of the user terminal 20. The summary creation screen C1 displays a character string saying "Please specify the financial data for which a summary is to be created", a target selection field D11, and a decision button B11. The financial data for which a summary is to be created is specified from the financial data stored in the financial database DB2 shown in Fig. 1 (hereinafter referred to as "stored financial data").

[0032] The target selection field D11 is an operation image for selecting financial data to be the subject of summary creation (hereinafter referred to as "target financial data") from the stored financial data. In the target selection field D11, "target company," "financial statement," "account item," "target period," "period unit," and "indicator type" are entered as information for selecting the target financial data. In "target company," a company or organization whose financial data will be analyzed is selected. In "financial statement," a balance sheet or profit and loss statement, etc., containing the financial data to be analyzed is selected.

[0033] In "Account item", the specific account item to be analyzed is selected. In "Target period", the period during which the economic activity indicated by the financial data to be analyzed took place is selected. In "Period unit", the unit of time for analyzing the financial data (monthly or yearly, etc.) is selected. In "Indicator type", the type of indicator of the financial data to be analyzed (current year value or year-on-year comparison, etc.) is selected. Selection in the target selection field D11 may be made by entering a string from the keyboard, or by displaying a pull-down list (a list based on the stored financial data) and allowing the user to make a selection.

[0034] In the example of FIG. 5, among the "accounts receivable" included in the "balance sheet" of "Company A," the "year-on-year change" of the "monthly" accounts receivable for "2021-2022 fiscal year" is selected as the target financial data. When the decision button B11 is operated, the financial data selected in the target selection field D11 is determined as the target financial data. The user terminal 20 accepts, at A21, the input to the target selection field D11 and the operation of the decision button B11 as a selection operation of the target financial data.

[0035] When selecting the target financial data, the user terminal 20 may display a list of the financial data selected in the target selection field D11 so that the selected financial data can be confirmed. Instead of allowing the user to select the target financial data in the target selection field D11, the user terminal 20 may display a list of stored financial data and allow the user to select the target financial data from the list. Next, the user terminal 20 accepts an instruction to create a financial summary at A22. A financial summary is a document summarizing the results of an analysis of the trends in the numerical values ​​indicated by the target financial data. When the target financial data is selected, the user terminal 20 displays an instruction screen for creating a financial summary.

[0036] 6 is a diagram showing an example of a financial summary creation instruction screen. The user terminal 20 displays a financial summary creation instruction screen C2 including a character string "Please instruct the creation of a financial summary", an outline of the target financial data D21, an input field E21 for instructions to create a financial summary, a back button B21, and a creation start button B22. The outline D21 of the target financial data shows information such as the "target company" selected in the target selection field D11 shown in FIG. 5.

[0037] The back button B21 is an operation image for returning to the previous screen (summary creation screen C1 shown in FIG. 5). When returning to the previous screen with the back button, the operations available on that screen can be performed again. For example, when operating the back button B21 to return to the summary creation screen C1, the target financial data can be reselected. In the summary creation system 1, similarly in the screens described below, the operation on the previous screen can be redone by returning to the screen with the back button.

[0038] The financial summary creation instruction input field E21 is an input field for entering instructions to create a financial summary. Instructions to create a financial summary are given by sentences that indicate instructions to the AI, known as prompts. In the example of Figure 6, the following prompt has been entered in the creation instruction input field E21: "The target financial data shows the year-on-year increase / decrease in monthly accounts receivable for Company A. The accounting period for this company is from December to November of the following year. Explain the trends in this data. Please do not explain the factors or reasons why such trends are observed."

[0039] The server device 10 may create a prompt based on information included in the summary D21 of the target financial data. In this case, the server device 10 creates a prompt by, for example, storing a template for a prompt in which unique information is embedded, and embedding the information included in the summary D21 as unique information. In this case, the creation instruction input field E21 does not need to be displayed.

[0040] When the creation start button B22 is operated, the user terminal 20 accepts the input prompt at A22 as an instruction to create a financial summary, and transmits financial creation instruction data indicating the selected target financial data and the text of the creation instruction to the server device 10. When the financial creation instruction data is transmitted, the server device 10 acquires the target financial data indicated by the financial creation instruction data at A23, and inputs the acquired target financial data to the trend determination AI module 120. In the following figures, the summary creation AI module 110 is referred to as the "first AI", the trend determination AI module 120 as the "second AI", and the factor determination AI module 130 as the "third AI".

[0041] Next, in A24, the server device 10 instructs the trend determination AI module 120 (second AI) to output the trend of the numerical values ​​indicated by the target financial data based on the creation instruction indicated by the financial creation instruction data. The trend determination AI module 120 generates and outputs a sentence indicating the numerical value trend based on the input target financial data.

[0042] In A25, the server device 10 acquires the text output from the trend determination AI module 120 as a financial summary of the target financial data. In this manner, the server device 10 generates a financial summary using the trend determination AI module 120. The server device 10 transmits the generated financial summary to the user terminal 20. In A26, the user terminal 20 displays the transmitted financial summary.

[0043] 7 is a diagram showing an example of a displayed financial summary. The user terminal 20 displays a financial summary display screen C3 including a character string "Financial summary has been created," an overview D21 of the target financial data, a financial summary F31, a back button B31, and a journal summary creation button B32. The back button B31 is an operation image for returning to the previous screen (the financial summary creation instruction screen C2 shown in FIG. 6).

[0044] Financial summary F31 shows, in text form, trend 1: "1. Monthly fluctuations: The increase or decrease in accounts receivable varies greatly from month to month. For example, there is a large increase from December in January, an even larger increase in February, and a fairly small increase in March." trend 2: "2. Magnitude: There are months in which the increase or decrease in accounts receivable exceeds 500 million yen (e.g. August, September, October, November)." trend 2: "3. Total compared to the same month of the previous year: The cumulative increase or decrease in accounts receivable from December to November of the following year is... This is the net fluctuation for the year, and shows that accounts receivable increased by this much over the course of 12 months." trend 3:

[0045] Financial summary F31 also shows trend 4, "4. High peak: The year-on-year changes in accounts receivable were the largest in February, August, October, and November, all exceeding 300 million yen," and trend 5, "5. Relative low: Conversely, the year-on-year changes in accounts receivable were relatively small in December, March, June, and July, falling well below 100 million yen." In this way, a financial summary is created from the target financial data.

[0046] After the financial summary is created, a process of creating a journal entry summary is performed. A journal entry summary is a document summarizing the results of an analysis of the journal entries that caused the trend in the numerical values ​​indicated by the financial summary. To proceed to creating a journal entry summary, the user operates the journal entry summary creation button B32. Then, the user terminal 20 first displays a journal entry summary creation screen for creating a journal entry summary.

[0047] 8 is a diagram showing an example of a displayed journal entry summary creation screen. The user terminal 20 displays a journal entry summary creation screen C4 including a character string "Please specify the journal entry data for which a summary is to be created," a target selection field D41, journal entry data D42, a back button B41, and a decision button B42. The journal entry data for which a summary is to be created is specified from the journal entry data stored in the journal entry database DB1 shown in FIG. 1 (hereinafter referred to as "stored journal entry data").

[0048] The target selection field D41 is an operation image for selecting the journal data for which a summary is to be created (hereinafter referred to as "target journal data") from the stored journal data. The target selection field D41 displays "target company," "client," "account item," and "target period" as information for selecting the target journal data. "Target company," "account item," and "target period" display the information selected when creating the financial summary. "Client" selects a company that does business with the target company.

[0049] The "business partner" may be selected by inputting a character string from the keyboard, or by displaying a pull-down list (a list based on stored journal data) and making a selection. In the example of FIG. 8, "Company D" is selected as the "business partner." When a "business partner" is selected, the user terminal 20 displays the journal data between the selected business partner and the target company. In the example of FIG. 8, journal data D42 of transactions between companies A and D is displayed.

[0050] The displayed journal data D42 may be used to create the journal summary, or the range to be used to create the journal summary may be selected. When the decision button B42 is operated, the journal data selected in the target selection field D41 is determined as the target journal data. The user terminal 20 accepts, in A31, the input to the target selection field D41 and the operation of the decision button B42 as the selection operation of the target journal data.

[0051] The method of selecting the target journal data is not limited to this, and for example, a list of stored journal data may be displayed and the target journal data may be selected from the list. Also, multiple business partners may be selected at the same time. When the target journal data is selected as described above, the user terminal 20 displays a screen instructing the creation of a journal summary. The creation of the journal summary is performed by the factor determination AI module 130.

[0052] 9 is a diagram showing an example of a journal summary creation instruction screen. The user terminal 20 displays a journal summary creation instruction screen C5 including a character string "Please instruct the creation of a journal summary.", an outline D51 of the input data to be input to the factor determination AI module 130, a journal summary creation instruction input field E51, a back button B51, and a creation start button B52. The back button B51 is an operation image for returning to the previous screen (the journal summary creation screen C4 shown in FIG. 8).

[0053] In the example of Fig. 9, the input data overview D51 shows the financial summary F31 of company A shown in Fig. 7 and the journal entry data D42 of companies A and D shown in Fig. 8. The journal entry summary creation instruction input field E51 is an input field for inputting instructions for creating a journal entry summary. In the creation instruction input field E51, a prompt representing an instruction for creating a journal entry summary is entered, as in the case of the financial summary.

[0054] In the example of Fig. 9, the prompt "Data 1 is a summary summarizing the trends of accounts receivable for Company A compared to the same month of the previous year for each month. Data 2 is a table summarizing journal entry data regarding transactions between Company A and Company D. Using these two data, explain the factors that caused the trends written in the financial summary from the journal entry data. However, do not explain trends that are not written in the financial summary or factors that cannot be determined from the journal entry data" is input in the creation instruction input field E51. Note that in this case, as in the example described in Fig. 6, the server device 10 may also create a prompt based on information included in the input data summary D51.

[0055] When the creation start button B52 is operated, the user terminal 20 accepts the input prompt as an instruction to create a journal summary in A32, and transmits journal entry creation instruction data indicating the created financial summary, the selected target journal entry data, and the creation instruction text to the server device 10. When the journal entry creation instruction data is transmitted, the server device 10 inputs the financial summary and the target journal entry data indicated by the journal entry creation instruction data to the factor determination AI module 130 (third AI) in A33.

[0056] Next, in A34, the server device 10 instructs the factor determination AI module 130 (third AI) to output the factors of the trend of the numerical values ​​indicated by the target journal data based on the creation instruction indicated by the journal creation instruction data. The factor determination AI module 130 generates and outputs a sentence indicating the factors of the numerical value trend based on the input financial summary and the target journal data.

[0057] The server device 10 acquires the text output from the factor determination AI module 130 as a journal entry summary of the target journal entry data in A35. The server device 10 generates a journal entry summary using the factor determination AI module 130 in this manner. The server device 10 transmits the generated journal entry summary to the user terminal 20. The user terminal 20 displays the transmitted journal entry summary in A36.

[0058] Fig. 10 is a diagram showing an example of a displayed journal entry summary. The user terminal 20 displays a journal entry summary display screen C6 including a character string "Journal entry summary has been created," an overview of input data D51 shown in Fig. 9, a journal entry summary F61, a back button B61, and a final summary creation button B62. The back button B61 is an operation image for returning to the previous screen (the journal entry summary creation instruction screen C5 shown in Fig. 9).

[0059] Journal entry summary F61 indicates factor 1 in the form of "1. Monthly fluctuations: The increase or decrease in accounts receivable varies greatly from month to month. This difference is due to various transactions, such as the difference in bad debt losses, the ToC department, and the ToB department. For example, in January, Company No. 1's accounts receivable increased from the ToC department compared to December, and in June it decreased significantly due to bad debt losses." and factor 2 in the form of "2. Magnitude: The large fluctuations in accounts receivable, especially in August, September, October, and November, are largely due to transactions with the ToC department. The items for these months have high absolute values."

[0060] In addition, journal entry summary F61 states in text that factor 3 is, "3. Total compared to the same month of the previous year: The cumulative change in accounts receivable from December to November can be explained by related transactions in the journal entry data," factor 4 is, "4. High peak: The large year-on-year fluctuations in accounts receivable in February, August, October, and November are likely due to high values ​​in these months, especially for transactions related to the toC division," and factor 5 is, "5. Relative low: The relatively small fluctuations in December, March, June, and July are seen in certain transactions such as those related to unearned revenue in the toB division."

[0061] Factors 1 to 5 for "Monthly Fluctuation," "Magnitude," "Total Compared to Same Month of Last Year," "High Peak," and "Relative Low" represent trends 1 to 5 included in financial summary F31 shown in Fig. 7, that is, factors that caused trends 1 to 5 in the same numerical values ​​for "Monthly Fluctuation," "Magnitude," "Total Compared to Same Month of Last Year," "High Peak," and "Relative Low." Fig. 10 shows a journal entry summary based on journal entry data with company D, but a journal entry summary based on journal entry data with company E will be explained with reference to Fig. 11.

[0062] 11 is a diagram showing another example of a displayed journal entry summary. Journal entry summary F61 for Company E indicates, in the form of text, factor 1, "1. Monthly fluctuation: This can be seen in the fluctuation in the debit amount for each month, with a large increase from December to January and an even larger increase in February. The variation in these figures across different rows for different companies or departments reflects the large changes from month to month." and factor 2, "2. Magnitude: High figures for certain months, such as August to November, indicate periods of high activity. We can see that the debit amounts for these months are over 500 million."

[0063] In addition, journal entry summary F61 indicates factor 3 in the form of, "3. Total compared to the same month last year: The cumulative change can be inferred from the total debit amounts, which matches the total year-on-year change shown in the financial summary," and factor 4 in the form of, "4. High peak: From the journal entry data for February, August, October, and November, we can see that these are the months with the largest year-on-year changes in accounts receivable. These can be observed from the corresponding debit amounts."

[0064] Furthermore, the journal entry summary F61 indicates factor 5 in the form of a sentence: "5. Relatively low value: Similarly, in the journal entry data, the values ​​for December, March, June, and July are low. The values ​​for these months are well below 100 million, which is consistent with the observation of the relatively low level in the financial summary." In this manner, the journal entry summary is created from the financial summary and the target journal entry data. In this embodiment, it is assumed that the journal entry summary is created based on the journal entry data for companies F, G, and H in addition to companies D and E.

[0065] After the journal summary is created, a process of creating a final summary is performed. The final summary is a document summarizing the trends of the values ​​indicated by the financial summary and the factors behind the trends of the values ​​indicated by the journal summary. If the user wishes to proceed to creating a final summary, the user operates the Create Final Summary button B62. Then, the user terminal 20 first displays a final summary creation screen for creating a final summary. The creation of the final summary is performed by the summary creation AI module 110.

[0066] 12 is a diagram showing an example of a final summary creation instruction screen. The user terminal 20 displays a final summary creation instruction screen C7 including a character string "Please instruct the creation of a final summary," an outline D71 of input data to be input to the summary creation AI module 110, a final summary creation instruction input field E71, a back button B71, and a creation start button B72. The back button B71 is an operation image for returning to the previous screen (the journal entry summary display screen C6 shown in FIG. 10 or FIG. 11).

[0067] In the example of Fig. 12, the input data overview D71 shows the financial summary F31 of company A shown in Fig. 7 and the journal entry summary F61 shown in Fig. 10 and Fig. 11. The final summary creation instruction input field E71 is an input field for inputting instructions for creating a final summary. A prompt representing an instruction for creating a final summary is entered in the creation instruction input field E71, as in the case of the financial summary and the journal entry summary.

[0068] In the example of FIG. 12, a prompt is entered in the creation instruction input field E71, stating, "Data 1 is a financial summary summarizing the trend of the increase / decrease in Company A's "accounts receivable" from December 2021 to November 2022 compared to the same month of the previous year. Data 2 is a journal entry summary summarizing the trend of Company A's journal entry data. Journal entry data with the debit account item being accounts receivable was extracted for trading partner companies D, E, F, G, and H, and a journal entry summary for each was created. Using data 1 and 2, explain the factors of the trends described in Company A's accounts receivable summary data based on the journal entry summary data. If the factors cannot be determined from the journal entry summary data, state that you do not know. ". In this case, as in the example described in FIG. 6, the server device 10 may create a prompt based on the information included in the input data summary D51.

[0069] When the creation start button B72 is operated, in A41, the user terminal 20 accepts the creation instruction entered in the creation instruction input field E71 as an instruction to create a final summary, and transmits final creation instruction data indicating the created financial summary, the created journal entry summary, and the text of the creation instruction to the server device 10. When the final creation instruction data is transmitted, in A42, the server device 10 inputs the financial summary and journal entry summary indicated by the final creation instruction data to the summary creation AI module 110 (first AI).

[0070] Next, in A43, the server device 10 instructs the summary creation AI module 110 (first AI) to output a final summary that combines the financial summary and the journal entry summary based on the creation instruction indicated by the final instruction data. The summary creation AI module 110 generates and outputs the final summary based on the input financial summary and journal entry summary.

[0071] In A44, the server device 10 acquires the text output from the summary creation AI module 110 as a final summary of the target financial data and the target journal entry data. In this manner, the server device 10 generates a final summary using the summary creation AI module 110. The server device 10 transmits the generated final summary to the user terminal 20. In A45, the user terminal 20 displays the transmitted final summary.

[0072] Fig. 13 is a diagram showing an example of a displayed final summary. The final summary display screen C8 shown in Fig. 13 displays the character string "Final summary has been created", the outline of the input data D71 shown in Fig. 12, the final summary F81, a back button B81, and a save button B82. The back button B81 is an operation image for returning to the previous screen (the final summary creation instruction screen C7 shown in Fig. 12).

[0073] Final summary F81 presents summary 1, "1. Monthly fluctuations: The accounting entries of several companies show large variations between successive months. The toC and toB divisions contribute to these fluctuations. Not all companies have data for each month, and there may be some companies that do not contribute much to the overall fluctuations."; and summary 2, "2. Magnitude: The high figures seen from August to November, for example, are reflected in the accounting entries of some companies, but not all companies. In addition, there are some companies that show relatively low values ​​without explaining their magnitude."

[0074] In addition, Final Summary F81 states in the text Summary 3 that "3. Year-on-year change total: The cumulative increase or decrease can be tracked through various subaccounts and business partners, but not all companies' accounting data can fully explain this figure. Transactions other than those provided in the accounting data must contribute to the total fluctuation." and Factor 4 that "4. High peaks: The high year-on-year changes in February, August, October, and November are consistent with the accounting data of some companies. Other customers or factors not included in the data provided may be influencing these peaks."

[0075] In addition, Final Summary F81 indicates factor 5 in the following text: "5. Relative Lows: The low values ​​for December, March, June, and July can be traced back to specific accounts and subaccounts in some company data. However, not all company data provide information for these months, so other factors may have contributed to these relative lows."

[0076] The final summary F81 can be modified by a user operation. The user checks the displayed final summary F81, modifies it if necessary, and then operates the save button B82. When the save button B82 is operated, the server device 10 stores the final summary F81. At that time, the server device 10 may store the target financial data, financial summary, target journal data, journal summary, and each prompt used when generating the final summary F81 in association with each other. In this way, the results of the analysis of the numerical data group and the data that became the material for the analysis are stored.

[0077] As described above, the server device 10 executes an acquisition step of acquiring stored journal data as the first numerical data group and acquiring stored financial data as the second numerical data group. The second numerical data group is a data group including numerical values ​​derived from the first numerical data group. For example, the stored financial data includes numerical values ​​of sales and accounts receivable, etc., derived from the stored journal data. A23 and A33 shown in FIG. 4, i.e., A23 in which the server device 10 acquires the target financial data as an example of the second numerical data group and A33 in which the server device 10 acquires the target journal data as the first numerical data group, are examples of an acquisition step.

[0078] The server device 10 executes a generating step of making the first artificial intelligence module generate text indicating the trend of the numbers indicated by the second numerical data group and the factors of the trend indicated by the first numerical data group, based on the first numerical data group and the second numerical data group acquired in the acquiring step. The summary creating AI module 110 is an example of a first artificial intelligence module, and the final summary F81 is an example of text indicating the trend of the numbers and the factors of the trend. A42 and A43, in which the server device 10 makes the summary creating AI module 110 generate the final summary, are examples of the generating step.

[0079] The first artificial intelligence module is an artificial intelligence module that performs learning based on a data group (e.g., LLM) including natural language, and outputs a sentence according to input information. The server device 10 executes a display step of performing a display process for displaying the sentence generated in the generation step on a display means. A44 in which the server device 10 displays the final summary F81 on the user terminal 20 is an example of the display step. According to this embodiment, the displayed final summary not only makes it possible to grasp the trend of the numerical values ​​indicated by the second numerical data group, but also makes it possible to grasp the factors behind the trend.

[0080] The server device 10 also executes a first determination step of making a trend determination on the trend of the numerical values ​​indicated by the second numerical data group, based on the second numerical data group acquired in the acquisition step. In the embodiment, the server device 10 inputs the second numerical data group to a second artificial intelligence module in A25 shown in FIG. 4, and the output by the second artificial intelligence module is the result of the trend determination. The trend determination AI module 120 is an example of a second artificial intelligence module. A23 to A25 shown in FIG. 4 are steps of acquiring a financial summary as a result of the trend determination, and are an example of the first determination step.

[0081] The second artificial intelligence module is an artificial intelligence module that can perform learning based on a data group including natural language and output a sentence showing the result of analyzing the trend of an inputted numerical value, like the trend determination AI module 120. According to this embodiment, the trend determination result can be made easier for people to understand than when the trend determination result is not in a sentence.

[0082] The server device 10 also executes a second determination step of performing factor determination on the factors of the determined numerical value trend based on the acquired first numerical data group. In the embodiment, the server device 10 inputs the trend determination result and the first numerical data group to the third artificial intelligence module in A35 shown in FIG. 4, and the output by the third artificial intelligence module is the result of the factor determination. The factor determination AI module 130 is an example of the third artificial intelligence module. A33 to A35 shown in FIG. 4 are steps of obtaining a journal entry summary as a result of the factor determination, and are an example of the second determination step.

[0083] The third artificial intelligence module is an artificial intelligence module that can perform learning based on a data group including natural language and output a sentence that analyzes the factors of the trend of the input numerical value, like the factor determination AI module 130. According to this embodiment, the result of the factor determination can be made easier for people to understand than when the result of the factor determination is not in the form of a sentence.

[0084] Furthermore, the server device 10 generates a final summary by inputting the trend judgment result and the factor judgment result to the first artificial intelligence module. In the embodiment, the server device 10 inputs the financial summary, which is the trend judgment result, and the journal entry summary, which is the factor judgment result, to the summary creation AI module 110, which is an example of the first artificial intelligence module, at A42. According to this aspect, it is possible to eliminate the need for judgment functions such as trend judgment and factor judgment in the first artificial intelligence module.

[0085] <Modification: Display of financial summary and journal entry summary> In the embodiment, the server device 10 only displays the final summary on the display screen C8 of the final summary shown in Fig. 13, but may display, for example, materials for judging whether the text of the final summary is appropriate or not. Such judgment materials include, for example, the financial summary and the journal summary used to generate the final summary.

[0086] In this case, the server device 10 executes a display step of performing a process for displaying either or both of the trend judgment result and the factor judgment result corresponding to the sentence (final summary) generated in the generation step as a display process. The server device 10 displays a display screen of the final summary that accepts an operation for executing such a display process.

[0087] Fig. 14 is a diagram showing an example of a display screen of the displayed final summary. In the display screen C9 of the final summary shown in Fig. 14, a financial summary display button B91 and a journal entry summary display button B92 are additionally displayed in addition to what is displayed on the display screen C8 shown in Fig. 13. When the financial summary display button B91 is operated, the server device 10 reads and displays the financial summary shown in data 1 of the input data summary D71, that is, the financial summary F31 used when generating the final summary F81.

[0088] Fig. 15 is a diagram showing an example of a displayed financial summary. On the final summary display screen C9 shown in Fig. 15, the financial summary F31 shown in Fig. 7 is displayed instead of the final summary F81, and a final summary display button B93 is displayed instead of the financial summary display button B91. When the final summary display button B93 is operated, the server device 10 displays the final summary F81 alongside the financial summary F31, allowing the two summaries to be compared.

[0089] When the journal entry summary display button B92 is operated on the display screen C9, the server device 10 reads out and displays the journal entry summary represented in data 2 of the input data summary D71, i.e., the journal entry summary F61 used when generating the final summary F81.

[0090] Fig. 16 is a diagram showing an example of a displayed journal summary. In the final summary display screen C9 shown in Fig. 16, the journal summary F61 shown in Fig. 10 and Fig. 11 is displayed instead of the final summary F81, and the final summary display button B93 is displayed instead of the journal summary display button B92. Note that since the journal summary F61 is generated only for transactions with five companies, if it does not fit on the screen, the journal summary F61 for each transaction can be displayed by scrolling.

[0091] When the display final summary button B93 is operated, the server device 10 displays the final summary F81 alongside the journal summary F61, allowing the two summaries to be compared. According to the above embodiment, the user can visually compare the final summary F81 with the financial summary F31 or the journal summary F61, making it easier to find grounds for examining the text of the final summary.

[0092] The server device 10 may also perform, as a display process, a process for displaying either or both of the result of the trend judgment and the result of the factor judgment corresponding to a portion of the displayed final summary designated by the user. The operation method by the user and the information displayed in this case will be described with reference to Figs. 17 and 18.

[0093] Fig. 17 is a diagram showing another example of the display screen of the displayed final summary. In the display screen C9 of the final summary shown in Fig. 17, a selection image G91 for selecting the portion of the description related to "3. Year-on-year comparison total" is displayed in the display screen C9 shown in Fig. 14. The portion selected by the selection image G91 is an example of "a portion of the text of the final summary designated by the user."

[0094] When the financial summary display button B91 is operated in this state, the server device 10 extracts a portion related to the selected portion from the financial summary shown in data 1 of the input data summary D71, i.e., the financial summary F31 used in generating the final summary F81. The server device 10 also extracts a portion corresponding to the selected portion from the journal entry summary shown in data 2 of the input data summary D71, i.e., the journal entry summary F61 used in generating the final summary F81. The server device 10 causes the user terminal 20 to display the extracted portions of the financial summary F31 and the journal entry summary F61 thus extracted.

[0095] Fig. 18 is a diagram showing an example of a displayed extracted portion. In the display screen C9 of the final summary shown in Fig. 18, a character string "A summary corresponding to the final summary has been displayed", a selected portion H91 selected in the final summary F81, an extracted portion H92 described for "3. Total compared to the same month of the previous year" in the financial summary F31 shown in Fig. 7, and an extracted portion H93 described for "3. Total compared to the same month of the previous year" in the journal entry summary F61 of each company and other companies shown in Figs. 10 and 11 are displayed. The extracted portion H93 in the journal entry summary F61 is scrolled to display the extracted portion H93 in the transaction with each company.

[0096] The server device 10 may display the selected portion H91 and the extracted portions H92, H93 of the final summary together as in the example of Fig. 18, but is not limited to this and may display them in order by switching pages. Regardless of the display mode, the final summary F81, financial summary F31, and journal entry summary F61 can be compared for the portion selected by the user. According to this mode, compared to the case where the entire judgment result is always displayed, text that is narrowed down to the portion to be compared is displayed, making it easier to compare the text of the final summary with the judgment result.

[0097] <Modification: Display of financial data and journal entry data> In the above example, the server device 10 displays the financial summary or the journal summary to examine the text of the final summary, but the present invention is not limited to this and may display the numerical data on which the summaries are based. In this case, the server device 10 performs a process for displaying the numerical data corresponding to the portion of the text of the displayed final summary designated by the user as a display process. The operation method by the user and the information displayed in this case will be described with reference to Figs. 19 and 20.

[0098] Fig. 19 is a diagram showing another example of a display screen of the displayed final summary. In the display screen C10 of the final summary shown in Fig. 19, the input data outline D71 shown in Fig. 12, the final summary F81 shown in Fig. 13, a back button B81, a save button B82, a display summary button B101, and a display data button B102 are displayed. In the display screen C10, a selection image G101 for selecting the entry for "3. Year-on-year comparison total" is displayed.

[0099] When the summary display button B101 is operated in this state, the server device 10 displays the parts related to the selected part from the financial summary F31 and journal entry summary F61 used in generating the final summary F81, as in the example of Fig. 18. Furthermore, when the data display button B102 is operated, the server device 10 extracts the parts corresponding to the selected part from the financial data and journal entry data used in generating the final summary F81. The server device 10 displays the extracted parts of the financial data and the extracted parts of the journal entry data thus extracted on the user terminal 20.

[0100] Fig. 20 is a diagram showing an example of a displayed extracted portion. In the display screen C10 of the final summary shown in Fig. 20, a character string "The data corresponding to the final summary has been displayed", a selected portion H101 of the final summary F81, a financial portion D101 corresponding to the portion H101 of the financial data, a journal entry portion D102 corresponding to the portion H101 of the journal entry data, a back button B111, a save button B112, a financial summary display button B113, and a journal entry summary display button B114 are displayed.

[0101] Since the journal entry locations D102 are extracted only for transactions with five companies, the journal entry locations D102 for each transaction can be displayed by scrolling. When the financial summary display button B113 is operated, the server device 10 displays the financial summary generated based on the financial location D101 (extracted location H92 of the financial summary shown in FIG. 18). When the journal entry summary display button B114 is operated, the server device 10 displays the journal entry summary generated based on the journal entry location D102 (extracted location H93 of the journal entry summary shown in FIG. 18).

[0102] 20, when examining the text of the final summary, the data on which the text is based can be viewed, making it possible to find more specific grounds than when examining the financial summary and journal entry summary. Also, since it is possible to switch between displaying the financial summary and journal entry summary corresponding to a selected portion of the final summary and displaying the financial data and journal entry data corresponding to the same portion, the text of the final summary can be examined from more diverse perspectives than when this switching is not possible.

[0103] <Modification: Reassessment of factors> The stored journal data includes multiple types of journal data, such as journal data showing transactions with company D and journal data showing transactions with company E. In this way, the first numerical data group may include multiple types of numerical data groups. Here, when the text of the final summary generated in the generation step does not satisfy a predetermined condition, the server device 10 may perform factor determination using a numerical data group of a different type from the first numerical data group used to generate the text as the first numerical data group.

[0104] For example, when the degree of certainty of the sentences indicated by the final summary is less than a threshold, the server device 10 determines that the sentences in the final summary do not satisfy the predetermined condition. The degree of certainty of a sentence is expressed, for example, by the ratio of the number of sentences that are not definitive, such as "may," "should," and "possible," to the number of sentences included in the final summary, and the smaller this ratio, the higher the degree of certainty. Note that the predetermined condition is not limited to this. For example, the server device 10 may determine that the predetermined condition is not satisfied when the amount of sentences in the final summary is less than a threshold.

[0105] Also, whether or not the final summary satisfies a predetermined condition may be determined by a human. In this case, the server device 10 displays, for example, a re-determination button on the display screen C8 of the final summary shown in Fig. 13, which indicates that the text of the final summary does not satisfy the predetermined condition and therefore the factor determination is to be performed again. When the re-determination button is operated, the server device 10 determines that the text of the final summary has been determined by a human to not satisfy the predetermined condition, and performs the factor determination again.

[0106] If the final summary F81 does not satisfy the predetermined conditions with the journal data of companies D, E, F, G, and H, the server device 10 further acquires journal data of company I, performs factor determination again, and regenerates the final summary, for example. Also, if the final summary does not satisfy the predetermined conditions even after acquiring the journal data of company I, the server device 10 further acquires journal data of company J, performs factor determination again, and regenerates the final summary. In this way, the server device 10 may repeatedly perform factor determination and regenerate the final summary until the final summary satisfies the predetermined conditions.

[0107] In the above example, the server device 10 acquires additional journal data while leaving the acquired journal data unchanged. However, this is not limited to the above, and for example, the server device 10 may discard a portion of the acquired journal data and acquire new journal data. The server device 10 may also discard a portion of the acquired journal data and perform factor determination again without acquiring new journal data. The journal data to be acquired again may also be determined by a person. According to such an embodiment, the accuracy of factor determination can be improved compared to the case where factor re-determination is not performed.

[0108] <Variation: Feedback on corrections> As described above, the final summary may be revised by the user. In that case, the server device 10 may execute a revision acquisition step of acquiring revisions to the text of the displayed final summary, and may execute a learning step of making the first artificial intelligence module learn the revisions acquired in the revision acquisition step.

[0109] The first artificial intelligence module is, for example, the summary creation AI module 110. As described above, the summary creation AI module 110 is adjusted to realize a summary creation function that, when a financial summary and a journal summary are input, creates a final summary text that summarizes the trends of the numerical values ​​of the target financial data and the factors of the trends. The server device 10 adds a pair of the input financial summary and journal summary and the corrected final summary to the teacher data, and causes the summary creation AI module 110 to learn. By feeding back the correction results to the AI ​​in this way, the generated text can be closer to a text created by a person than when this feedback is not provided.

[0110] Similarly, in the learning step, the server device 10 may cause the second artificial intelligence module to learn the correction content acquired in the correction acquisition step. The second artificial intelligence module is, for example, the trend determination AI module 120. As described above, the trend determination AI module 120 is adjusted to realize a trend analysis function that analyzes the trend of the numerical values ​​indicated by the target financial data when the target financial data is input.

[0111] The server device 10 adds a pair of the input target financial data and the corrected final summary to the teacher data and causes the trend determination AI module 120 to perform learning. If the corrected portion of the final summary is also included in the financial summary used to generate the final summary, by feeding back this correction, the financial summary output by the trend determination AI module 120, i.e., the generated trend determination result, can be made closer to the result of a human determination than if this feedback is not provided.

[0112] In addition, in the learning step, the server device 10 may cause the third artificial intelligence module to learn the correction content acquired in the correction acquisition step. The third artificial intelligence module is, for example, the factor determination AI module 130. As described above, the factor determination AI module 130 is adjusted to realize a factor analysis function that analyzes the factors of the trend of the numerical values ​​indicated by the target journal entry data when the target journal entry data is input.

[0113] The server device 10 adds a pair of the input target journal data and the corrected final summary to the teacher data and causes the factor determination AI module 130 to learn. If the corrected portion of the final summary is also included in the journal summary used to generate the final summary, by feeding back this correction to the AI, the journal summary output by the factor determination AI module 130, i.e., the generated result of the factor determination, can be made closer to the result of a human determination than when this feedback is not provided.

[0114] It should be noted that the corrections fed back to the AI ​​module 100 are not limited to corrections to the final summary. Corrections to the financial summary may be made available, and the corrections to the financial summary may be fed back to the trend determination AI module 120. Also, corrections to the journal entry summary may be made available, and the corrections to the journal entry summary may be fed back to the factor determination AI module 130. In either case, the results of trend determination or factor determination can be made closer to the results of determination by a human, compared to when feedback is not provided.

[0115] <Variation: Configuration of artificial intelligence module> The artificial intelligence modules (summary creation AI module 110, trend determination AI module 120, and factor determination AI module 130) may be internal or external components of the server device 10, or may be internal or external components of the summary creation system 1. Furthermore, the function realized by one artificial intelligence module may be distributed and realized by two or more artificial intelligence modules, or the function realized by two or more artificial intelligence modules may be integrated and realized by one artificial intelligence module.

[0116] For example, the summary creation AI module 110 may be adjusted to realize a trend analysis function and a factor analysis function in addition to the text generation function and summary creation function described above. In this case, the server device 10 can generate text output by the summary creation AI module 110 as a final summary showing the trend of the values ​​indicated by the target financial data and the factors of the trend indicated by the target journal entry data simply by inputting the target financial data and the target journal entry data acquired in the acquisition step to the summary creation AI module 110.

[0117] The server device 10 may generate a final summary using only the summary creation AI module 110 and the trend determination AI module 120 (in this case, the summary creation AI module 110 performs factor determination), or may generate a final summary using only the summary creation AI module 110 and the factor determination AI module 130 (in this case, the summary creation AI module 110 performs trend determination). In this way, the range of functions realized by the AI ​​module 100 may be determined as necessary.

[0118] <Modification: Trend Judgment / Factor Judgment> In the embodiment, the server device 10 performed trend determination and factor determination using an AI module 100 (trend determination AI module 120 and factor determination AI module 130) that was adjusted to realize a sentence generation function, but this is not limited to the above, and trend determination and factor determination may also be performed using an AI module 100 that does not realize a sentence generation function.

[0119] Furthermore, the server device 10 may use an algorithm for determining a trend in a predetermined procedure based on the target financial data, or an algorithm for determining factors in a predetermined procedure based on the trend determination results and the target journal entry data, thereby performing trend determination and factor determination without using the AI ​​module 100. In either case, if the summary creation AI module 110 has performed learning using the trend determination results and factor determination results for each case, it can generate a final summary based on those determination results.

[0120] <Modification: First Numeric Data Group and Second Numeric Data Group> The first and second numerical data groups are not limited to financial data and accounting data. For example, the server device 10 may acquire, in A33, detailed expenditure data such as receipt data in a household accounting application, mail order purchase data, and credit card usage details data as the first numerical data group, and acquire, in A23, monthly expenditure data in which the numerical values ​​indicated by the first numerical data group are summarized by item (fixed cost, variable cost, etc.) as the second numerical data group.

[0121] In this case, the second numerical data group, which is monthly expenditure data, is a data group including numerical values ​​derived from the first numerical data group, which is detailed expenditure data. The period for which the expenditure data is compiled is not limited to one month, but may be any predetermined period such as one day, one week, one quarter, or one half year. The server device 10 then executes the summary creation process shown in Fig. 4, performs trend judgment on the tendency of the numerical values ​​indicated by the monthly expenditure data based on the acquired monthly expenditure data, and generates an expenditure trend summary instead of a financial summary in A25.

[0122] The server device 10 also performs a factor determination on the factors of the determined numerical trend based on the acquired detailed expenditure data, and generates an expenditure detail summary instead of a journal entry summary in A35. The server device 10 then causes the first artificial intelligence module to generate a final summary, which is a text indicating the numerical trend indicated by the monthly expenditure data and the factors of the trend indicated by the detailed expenditure data in A42 and A43, and performs a display process for displaying the generated text on a display means in A44. In this case, too, the displayed final summary allows the user to grasp not only the numerical trend indicated by the second numerical data group, but also the factors of the trend.

[0123] Alternatively, for example, meteorological data such as daily precipitation and temperature may be the first numerical data group, and meteorological information (e.g., monthly precipitation and monthly average temperature) that is a compilation of meteorological data for a predetermined period may be the second numerical data group. Furthermore, traffic data such as daily traffic volume at each observation point and the number of accidents in each region may be the first numerical data group, and traffic information that summarizes the number of accidents in a predetermined period by region (e.g., monthly number of accidents by region) may be the second numerical data group. In short, any data group may be used as long as the second numerical data group is a data group that includes numerical values ​​derived from the first numerical data group.

[0124] <Examples of variations: composition variations> The configuration (overall configuration, hardware configuration, functional configuration, etc.) shown in FIG. 1 etc. is an example, and other configurations may be used as long as there is no inconvenience in implementation. For example, the server device 10 may be distributed across two or more devices, and may be provided in the form of SaaS (Software as a Service) or a cloud computing system. Furthermore, the information processing executed by the server device 10 may be executed collectively by the user terminal 20. In short, as long as the necessary information processing is executed in the entire summary creation system 1, the devices that execute the information processing may have any configuration.

[0125] The output destination of information or data (hereinafter referred to as "information, etc.") may be another device, a display, a memory unit (including a built-in memory unit and an external memory unit), etc. Acquisition of information, etc. includes acquiring information, etc. generated by the device itself, in addition to acquiring information, etc. transmitted from another device. Tables, etc. (tables, databases, etc.) that associate parameters are not limited to the tables, etc. shown in the figures, and the number of parameters may be reduced or increased. Furthermore, information, etc. corresponding to parameters may be obtained by a formula, a conditional formula, etc., without using a table, etc.

[0126] The above-mentioned aspects of the embodiment are information processing devices such as the server device 10 and the user terminal 20, and information processing systems such as the summary creation system 1 including the server device 10 and the user terminal 20, but may also be information processing methods.
