Mode for Carrying Out the Invention

[0012] (Configuration of the Embodiment) Hereinafter, the embodiment will be described with reference to the drawings. FIG. 1 is a block diagram showing an example of the overall configuration of the information processing system 1.

[0013] As shown in FIG. 1, the information processing system 1 includes a terminal device 10 and a server 20. The terminal device 10 is connected to the server 20 via a network such as a LAN, the Internet, or mobile communication. The terminal device 10 is used by a user such as an accounting person in an organization such as a company.

[0014] FIG. 2 is a block diagram showing an example of the internal configuration of the information processing system 1. FIG. 3 is a block diagram showing an example of the functional configuration of the information processing system 1.

[0015] As shown in FIGS. 2 and 3, the terminal device 10 is an information terminal such as a personal computer or a smartphone, for example. The terminal device 10 includes a terminal control unit 11, a terminal storage unit 12, a display unit 13, and an instruction input unit 14.

[0016] The terminal control unit 11 has a processing device such as a CPU, and realizes its functions by executing a program read from the terminal storage unit 12.

[0017] The terminal storage unit 12 has storage elements such as a ROM, a RAM, a HDD, and a SSD, and stores various types of information for controlling the terminal device 10 and various programs constituting the processing unit.

[0018] The display unit 13 is composed of an LCD, LED, OLED, etc., and is capable of displaying various types of information input from the terminal control unit 11.

[0019] The instruction input unit 14 has, for example, an input device such as a keyboard or mouse, and outputs various instruction inputs entered by the user to the terminal control unit 11.

[0020] The server 20 has a control unit 21 and a storage unit 22.

[0021] The control unit 21 has a processing unit such as a CPU and realizes its function by executing a program read from the storage unit 22.

[0022] The storage unit 22 has memory elements such as ROM, RAM, HDD, and SSD, and stores various programs that constitute the processing unit for controlling the server 20, as well as various information used by the programs. For example, the storage unit 22 stores various information such as document information S and transaction information T, as well as various programs such as the business processing unit B, document reception unit P1, estimation unit P2, confirmed information reception unit P3, transaction registration unit P4, duplicate detection unit P5, and warning unit P6.

[0023] The document information S includes a document image M, which is an image of the document; estimated information U, which is estimated by character recognition of the document image M; confirmed information F, which is confirmed by the user based on the estimated information U; and transaction registration information R, which indicates whether or not the transaction has been registered. Each of these is associated with the others.

[0024] Transaction information T includes information used by the business processing unit B, such as income / expense classification, settlement status (whether pending or completed), account information (source of funds), transaction date, trading partner, account title, tax classification (consumption tax), consumption tax rate, and amount.

[0025] The business processing unit B, while not particularly limited, provides users with accounting services such as accounting journal entries, ledger creation, quotation creation, and invoice creation based on transaction information T.

[0026] Figure 4 shows an example of the document reception screen G1.

[0027] The document reception unit P1 displays the document reception screen G1 on the display unit 13 in response to the instruction input received from the terminal control unit 11, and accepts the input of a document image M. The document reception screen G1 is provided with a document reception area L, a list display area D, and a duplicate check button C, as well as various filtering buttons to display the information desired by the user, such as receipts, invoices, unregistered, and registered transactions. The document reception area L can accept document images M by the user through drag-and-drop operations or file selection operations. The accepted document images M are sent to the server 20. The list display area D displays the accepted document images M in a list. Each document image M displayed in the list display area D is marked with a transaction tag Dt indicating transaction registration information R so that the user can confirm whether or not the transaction has been registered.

[0028] The estimation unit P2 performs character recognition on the document image M, which is an image of the document that was received as input, and obtains estimated information U, which is stored in the storage unit 22. The estimated information U includes both the estimated amount Um and the estimated issue date Ui.

[0029] More specifically, the estimation unit P2 uses a large-scale language model constructed using machine learning techniques to perform character recognition on the document image M and obtains the estimated amount Um and estimated issue date Ui from the text obtained. The estimated amount Um and estimated issue date Ui may be obtained not only from a large-scale language model, but also from regular expressions used to extract amounts and dates from text obtained through character recognition, or from other methods. If the estimation unit P2 fails to obtain the information, the estimated amount Um and estimated issue date Ui will be set to unset values ​​such as empty strings or Null.

[0030] Figure 5 shows an example of the confirmed information reception screen G2.

[0031] The confirmed information receiving unit P3 presents the estimated information U estimated by the estimation unit P2 to the user on the confirmed information receiving screen G2 displayed on the display unit 13, accepts the input of confirmed information F confirmed by the user based on the estimated information U, and stores it in the storage unit 22. The confirmed information F includes the confirmed amount Fm corresponding to the estimated amount Um and the confirmed issue date Fi corresponding to the estimated issue date Ui.

[0032] More specifically, when a user presses the document image M displayed on the document reception screen G1, the confirmed information reception unit P3 displays the confirmed information reception screen G2 on the display unit 13, reads the estimated amount Um and estimated issue date Ui associated with the document image M from the storage unit 22, and displays the estimated amount Um and estimated issue date Ui together with the document image M in an editable state. The user compares the estimated amount Um and estimated issue date Ui with the document image M to see if they are correctly estimated, and if they are incorrect, inputs corrections. When the user presses the save button X, if there are no corrections, the confirmed information reception unit P3 accepts the estimated amount Um as the confirmed amount Fm and the estimated issue date Ui as the confirmed issue date Fi, and stores them in the storage unit 22. On the other hand, if there are corrections, the confirmed information reception unit P3 accepts the corrected estimated amount Um as the confirmed amount Fm and the corrected estimated issue date Ui as the confirmed issue date Fi, and stores them in the storage unit 22.

[0033] Figure 6 shows an example of the transaction registration screen G3.

[0034] The transaction registration unit P4 registers the transaction information T shown in the supporting document information S in response to the instruction input received from the user. More specifically, when the user presses the text link "Register Transaction" displayed on the confirmed information reception screen G2, the transaction registration unit P4 displays the transaction registration screen G3 and accepts the input of transaction information T. When the user enters the transaction information T and presses the transaction registration button Y, the transaction registration unit P4 stores the transaction information T in the storage unit 22 so that it can be used by the business processing unit B, and also stores transaction registration information R indicating that the transaction has been registered. Based on the registered transaction information T, the business processing unit B can provide business services such as accounting services to the user.

[0035] Figure 7 shows an example of a warning display on the document reception screen G1.

[0036] The duplicate detection unit P5 starts processing when the user presses the duplicate check button C on the document reception screen G1. The duplicate detection unit P5 obtains the source document information Ss, which is the source of the duplicate detection process, and the destination document information Sd, which is the destination of the duplicate detection process, from the document information S that is the target of the duplicate detection process. Under predetermined conditions, it performs a brute-force determination process on each of the source document information Ss and destination document information Sd to detect duplicate source document information Ss and destination document information Sd, and stores the detection results in the storage unit 22.

[0037] To reduce processing load, the duplicate detection unit P5 uses the transaction registration information R to designate the unregistered document information S as the source document information Ss, and both the unregistered and registered document information S as the destination document information Sd. By including the registered document information S in the destination document information Sd, it is possible to detect duplicate document information S in cases such as when a transaction is registered based on the document information S, and then the deletion of the transaction registration is deleted, but the deletion of the document information S is not completed.

[0038] Furthermore, if a user provides an instruction to display only duplicates of the transaction-registered document information S, the transaction-registered document information S will be used for both the source document information Ss and the destination document information Sd.

[0039] Figure 8 is an explanatory diagram illustrating the predetermined conditions for performing duplicate detection processing.

[0040] As shown in Figure 8, the predetermined conditions are determined to be duplicates if any of the following (a) to (c) are met.

[0041] (a) When confirmed information F included in the source document information Ss is entered, and the confirmed information F included in the source document information Ss is common with at least one of the confirmed information F or estimated information U included in the referenced document information Sd. To give a more specific example, when both the confirmed amount Fm and the confirmed issue date Fi included in the source document information Ss are entered, and at least both the confirmed amount Fm and the confirmed issue date Fi, or both the estimated amount Um and the estimated issue date Ui included in the source document information Ss, are common with both the confirmed amount Fm and the confirmed issue date Fi included in the referenced document information Sd (No. 1-4 in Figure 8).

[0042] (b) When confirmed information F included in the source document information Ss is entered and estimated information U is obtained, and the estimated information U included in the source document information Ss is common with at least one of the confirmed information F or estimated information U included in the referenced document information Sd. To give a more specific example, when both confirmed amount Fm and confirmed issue date Fi are entered in the source document information Ss and both estimated amount Um and estimated issue date Ui are obtained, and both estimated amount Um and estimated issue date Ui included in the source document information Ss are common with at least one of the confirmed amount Fm and confirmed issue date Fi, or both estimated amount Um and estimated issue date Ui included in the referenced document information Sd (No. 1 in Figure 8).

[0043] (c) When the confirmed information F included in the source document information Ss is not entered and the estimated information U is obtained, and the estimated information U included in the source document information Ss is common with at least one of the confirmed information F or the estimated information U included in the referenced document information Sd. To give a more specific example, when both the confirmed amount Fm and the confirmed issue date Fi included in the source document information Ss are not entered and both the estimated amount Um and the estimated issue date Ui are obtained, and both the estimated amount Um and the estimated issue date Ui included in the source document information Ss are common with at least one of the confirmed amount Fm and confirmed issue date Fi, or the estimated amount Um and the estimated issue date Ui included in the referenced document information Sd (No. 5 in Figure 8).

[0044] In the specified conditions, "common" includes not only cases where the values ​​of the items being judged match, but also cases where the values ​​of the items being judged are substantially the same, such as when their normalized values ​​match. Furthermore, if the values ​​of the source document information Ss and / or the destination document information Sd being processed are empty strings, NULL, or other unset values, they will not be included in the judgment, and no duplicates will be detected.

[0045] Figure 7 shows an example of the duplicate display screen G4.

[0046] As shown in Figure 7, once the duplicate detection process is complete, the warning unit P6 displays the duplicate display screen G4 to warn the user of the duplicates detected by the duplicate detection unit P5. More specifically, when the duplicate detection unit P5 detects a duplicate, the warning unit P6 displays the document images M contained in the source document information Ss and the referenced document information Sd, which have been found to be duplicates of each other, on the duplicate display screen G4.

[0047] On the duplicate display screen G4, it is possible to display duplicates of document information S that have not been registered and document information S that have been registered, display only duplicates of document information S that have been registered, display only duplicates of document information S with the same issuer, or display duplicates of uploaded dates within a desired range, depending on the user's input.

[0048] The user can select a duplicate evidence image M from the list display area D on the duplicate display screen G4, press the delete button Z, and input a deletion instruction.

[0049] (operation) Next, I will explain the duplicate detection process. Figure 9 is a flowchart showing an example of the duplicate detection process.

[0050] As shown in Figure 9, the duplicate detection unit P5 acquires the unregistered document information S as the source document information Ss based on the transaction registration information R (S1). Subsequently, the duplicate detection unit P5 acquires the unregistered document information S and the registered document information S as the destination document information Sd (S2).

[0051] The duplicate detection unit P5 performs a brute-force determination process under predetermined conditions by nesting the referenced document information Sd inside the referenced document information Ss (S3, S4, S7, S8), and determines whether each of the referenced document information Ss and each of the referenced document information Sd are duplicates. If duplicate referenced document information Ss and referenced document information Sd are detected based on the determination result (S5: YES), the detection result is stored in the storage unit 22 (S6).

[0052] The warning unit P6 reads the detection results of the duplicate detection process from the storage unit 22 and displays a warning on the duplicate display screen G4 regarding the duplicate document information S (S7).

[0053] (Effects and Benefits) According to Information Processing System 1, the following effects are achieved.

[0054] Even if the estimated information U is incorrect due to a misrecognition of the document image M by the confirmed information receiving unit P3, the corrected confirmed information F by the user is input. The duplicate detection unit P5 can use the confirmed information F to more accurately detect duplicate documents.

[0055] Furthermore, the confirmed information receiving unit P3 can detect duplicate documents early on when the document information S for which confirmed information F has not been entered is read, using estimated information U.

[0056] For estimated information U, if at least one of the estimated amount Um or the confirmed issue date Fi is not set, it is excluded from the duplicate determination. For document information S that is handwritten or illegible and difficult to estimate by character recognition, there is a high probability that at least one of the estimated amount Um or the confirmed issue date Fi will be an unset value. By excluding such document information S from the duplicate determination, duplicate documents can be detected more accurately.

[0057] Furthermore, if at least one of the confirmed amount Fm or confirmed issue date Fi is not set, the document is excluded from the duplicate detection. If the user fails to enter confirmed information F, there is a high probability that at least one of the confirmed amount Fm or confirmed issue date Fi will be an unset value. In such cases, the document information S can be excluded from the duplicate detection, allowing for more accurate detection of duplicate documents.

[0058] The duplicate detection unit P5 can reduce the processing load in the duplicate detection process by excluding the document information S that has been registered as a transaction and accounted for by the business processing unit B, and by using the document information S that has not been registered as a transaction as the source document information Ss.

[0059] According to this embodiment, the information processing system 1 can more accurately detect duplicate evidence and prevent the import of duplicate evidence.

[0060] In this embodiment, the duplicate detection unit P5 was described in examples such as detecting duplicates between unregistered document information S and registered document information S, and detecting only duplicates between registered document information S, but it is not limited to these examples. The duplicate detection unit P5 may also detect duplicates between all document information S, or it may use document information S received within a predetermined period as the source document information Ss.

[0061] Furthermore, although the embodiment described an example in which the warning unit P6 warns the user that a duplicate has been detected by displaying it on the screen, the invention is not limited to this, and the warning may be given by voice or other means.

[0062] Furthermore, although (a) to (d) have been described as predetermined conditions for performing duplicate detection processing in this embodiment, the embodiment is not limited thereto, and other conditions may be added. For example, in this embodiment, an example has been described in which the estimated information U includes an estimated amount Um, which is the first estimated information U, and an estimated issue date Ui, which is the second estimated information U, and the confirmed information F includes a confirmed amount Fm, which is the first confirmed information F, and a confirmed date information, which is the second confirmed information F, but the embodiment is not limited thereto. The first estimated information U and the first confirmed information F may be information such as the billed amount, the received amount, or the contract amount, and the second estimated information U and the second confirmed information F may be information such as the billing date, the receipt date, or the contract date. In addition, each of the estimated information U and confirmed information F may also include a third estimated information U and a third confirmed information F that indicate other information such as the issuer.

[0063] In other words, the information processing system 1 includes an estimation unit P2 that performs character recognition on a document image M, which is an image of a document that has been received as input, and obtains estimated information U; a confirmed information receiving unit P3 that presents the estimated information U obtained by the estimation unit P2 to the user and accepts input of confirmed information F that the user has confirmed based on the estimated information U; and a duplicate detection unit P5 that detects the duplication between a source document information S, which is the source document information S, and a destination document information S, which is the destination document information Sd. The duplicate detection unit P5 detects when confirmed information F included in the source document information Ss has been input, and when confirmed information F included in the source document information Ss is common with at least one of the confirmed information F or estimated information U included in the destination document information Sd, the source document information The system detects duplication between the report Ss and the referenced document information Sd. If confirmed information F included in the referenced document information Ss is entered and estimated information U is obtained, and the estimated information U included in the referenced document information Ss is common with at least one of the confirmed information F or estimated information U included in the referenced document information Sd, the system detects duplication between the referenced document information Ss and the referenced document information Sd. If confirmed information F included in the referenced document information Ss is not entered but estimated information U is obtained, and the estimated information U included in the referenced document information Ss is common with at least one of the confirmed information F or estimated information U included in the referenced document information Sd, the system detects duplication between the referenced document information Ss and the referenced document information Sd.

[0064] Confirmed information F consists of first confirmed information F corresponding to first estimated information U and second confirmed information F corresponding to second estimated information U. First estimated information U is the estimated amount Um. Second estimated information U is the estimated issue date Ui. First confirmed information F is the confirmed amount Fm. Second confirmed information F is the confirmed issue date Fi.

[0065] The duplicate detection unit P5 detects a duplicate between the source document information Ss and the referenced document information Sd when both the first confirmed information F and the second confirmed information F included in the source document information Ss are input, and both the first confirmed information F and the second confirmed information F included in the source document information Ss are common with at least both the first confirmed information F and the second confirmed information F, or both the first estimated information U and the second estimated information U, included in the referenced document information Sd. Furthermore, when both the first confirmed information F and the second confirmed information F included in the source document information Ss are input, and both the first estimated information U and the second estimated information U are obtained, the duplicate detection unit P5 detects a duplicate between the source document information Ss and the referenced document information Sd. If the referenced document information Ss contains at least both of the first confirmed information F and the second confirmed information F, or both of the first estimated information U and the second estimated information U, and both of these are common to the referenced document information Sd, then a duplication of the referenced document information Ss and the referenced document information Sd is detected. If the referenced document information Ss does not contain both the first confirmed information F and the second confirmed information F, but both of the first estimated information U and the second estimated information U are obtained, and both of the referenced document information Ss contains at least both of the first confirmed information F and the second confirmed information F, or both of the first estimated information U and the second estimated information U, and both of these are common to the referenced document information Sd, then a duplication of the referenced document information Ss and the referenced document information Sd is detected.

[0066] The transaction registration unit P4 registers the transaction indicated in the document information S in response to the instruction input received from the user, and the duplicate detection unit P5 uses the document information S for which no transaction registration has been made as the source document information Ss, and uses both the document information S for which no transaction registration has been made and the document information S for which a transaction has been made as the destination document information Sd.

[0067] The duplicate detection unit P5 uses the source document information Ss as the reference document information S that was received within a predetermined period.

[0068] The warning unit P6 warns the user of the duplicates detected by the duplicate detection unit P5 through a screen display. When the duplicate detection unit P5 detects a duplicate, the warning unit P6 warns the user by displaying on the screen the document images M contained in the source document information Ss and the referenced document information Sd, which have been found to be duplicates of each other.

[0069] The information processing method involves the estimation unit P2 performing character recognition on the document image M, which is an image of the document that has been received as input, to obtain estimated information U; the confirmed information receiving unit P3 presenting the estimated information U obtained by the estimation unit P2 to the user, receiving input of confirmed information F confirmed by the user based on the estimated information U; the duplicate detection unit P5 detecting duplicates between the source document information Ss, which is the source document information S, and the destination document information Sd, which is the referenced document information S; and if confirmed information F included in the source document information Ss has been input, the duplicate detection unit P5 determines if the confirmed information F included in the source document information Ss is common with at least one of the estimated information U or confirmed information F included in the destination document information Sd, then the source document information Ss The system detects duplication between the referenced document information Sd and the referenced document information Sd. When confirmed information F included in the referenced document information Ss is entered and estimated information U is obtained, the system detects duplication between the referenced document information Ss and the referenced document information Sd if the estimated information U included in the referenced document information Ss is common with at least one of either confirmed information F or estimated information U included in the referenced document information Sd. When confirmed information F is not entered in the referenced document information Ss but estimated information U is obtained, the system detects duplication between the referenced document information Ss and the referenced document information Sd if the estimated information U included in the referenced document information Ss is common with at least one of either estimated information U or confirmed information F included in the referenced document information Sd.

[0070] The information processing program includes the code of an estimation unit P2 that performs character recognition on a document image M, which is an image of a document that has been received as input, to obtain estimated information U; the code of a confirmed information receiving unit P3 that presents the estimated information U obtained by the estimation unit P2 to the user and accepts input of confirmed information F that the user has confirmed based on the estimated information U; and the code of a duplicate detection unit P5 that detects the duplication between a source document information S, which is a referenced document information S, and a referenced document information S, which is a referenced document information Sd. When confirmed information F included in the source document information Ss is input, and the confirmed information F included in the source document information Ss is common with at least one of the estimated information U or confirmed information F included in the referenced document information Sd, the duplicate detection unit detects the duplication between the source document information Ss and the referenced document information Sd. The code of the duplicate detection unit P5 is executed by the computer when a duplicate is detected, and when confirmed information F contained in the source document information Ss is input and estimated information U is obtained, and the estimated information U contained in the source document information Ss is common with at least one of confirmed information F or estimated information U contained in the referenced document information Sd, a duplicate of the source document information Ss and the referenced document information Sd is detected, and when confirmed information F contained in the source document information Ss is not input but estimated information U is obtained, and the estimated information U contained in the source document information Ss is common with at least one of estimated information U or confirmed information F contained in the referenced document information Sd, a duplicate of the source document information Ss and the referenced document information Sd is detected.

[0071] As described above, embodiments of the present invention have been explained, but the embodiments are not limited thereto, and various changes and modifications are possible as long as they do not alter the essence of the present invention.

[0072] Furthermore, each step of each procedure in the embodiment may be executed in a different order, executed simultaneously, or executed in a different order each time, as long as it does not contradict its nature. In addition, all or part of each step of each procedure in the embodiment may be implemented by hardware or by program. [Explanation of symbols]
