Modes for Carrying Out the Invention

[0009] Hereinafter, embodiments for implementing the information processing apparatus, information processing method, and information processing program according to the present application (hereinafter referred to as "embodiments") will be described in detail with reference to the drawings. Note that the information processing apparatus, information processing method, and information processing program according to the present application are not limited by these embodiments.

[0010] [Embodiment] [1. Information Processing] First, an example of the information processing according to the embodiment will be described with reference to FIG. 1. FIG. 1 is a diagram showing an example of the information processing according to the embodiment. Such an information processing method is executed, for example, by the information processing apparatus 1 shown in FIG. 1.

[0011] As shown in FIG. 1, the information processing apparatus 1 according to the embodiment is an information processing apparatus that provides various contents to the user terminal 50. For example, the information processing apparatus 1 provides contents related to news through a news site. Note that the information processing apparatus 1 is realized by, for example, a server device, a cloud system, or the like.

[0012] The user terminal 50 is a terminal device owned by the user U and is a terminal that displays the contents provided from the information processing apparatus 1 through data communication with the information processing apparatus 1. Examples of the user terminal 50 include a smartphone, a tablet terminal, a personal computer, a wearable terminal, and the like.

[0013] By the way, for example, among the news provided on a news site, in addition to the currently displayed news, some have a function of recommending other news such as "articles you may also want to read" below it.

[0014] Such recommended news only has a thumbnail displayed for each, and there is a problem that the click rate by the user U is low. Note that the invention of the present application is not limited to recommendations such as "articles you may also want to read" and can be appropriately applied to contents with thumbnails displayed.

[0015] In response to such problems, the information processing apparatus 1 according to the embodiment is configured to display, together with a thumbnail, a summary sentence of a landing page that transitions when the thumbnail is clicked.

[0016] Specifically, as shown in FIG. 1, the information processing apparatus 1 provides information regarding the top page of the news site to the user terminal 50 (step S1). Based on the information regarding the top page provided by the information processing apparatus 1, the top page of the news site will be displayed on the user terminal 50.

[0017] When the user U selects desired news from the top page displayed on the user terminal 50 (step S2), information regarding the news selected by the user U is provided to the information processing apparatus 1 (step S3).

[0018] Subsequently, the information processing apparatus 1 generates a news article based on the information acquired from the user terminal 50 (step S4). The news article here includes, in addition to the news selected by the user U, various comments posted for the news and information on the thumbnails of recommended news associated with the news.

[0019] Subsequently, the information processing apparatus 1 acquires information on the thumbnail to be displayed together with the news article and information on the landing page corresponding to the thumbnail, and generates a summary sentence summarizing the content of the landing page (step S5).

[0020] Specifically, when a natural language sentence is input, the information processing apparatus 1 uses a generation model that generates an answer to the input sentence in natural language to generate a summary sentence summarizing the content of the landing page. The generation model is, for example, a model such as GPT (Generative Pre-trained Transformer).

[0021] For example, the information processing apparatus 1 inputs a thumbnail, a landing page corresponding to the thumbnail, and an instruction sentence stating that the content of the landing page is to be summarized as a prompt into the generation model.

[0022] The generation model will generate a summary sentence summarizing the content of each landing page for each thumbnail in response to such a prompt. Subsequently, the information processing apparatus 1 provides display content to the user terminal 50 based on the generated summary sentence (step S6).

[0023] The display content is content that, in addition to the news article selected by the user U, displays a summary sentence summarizing the content of the landing page displayed when the thumbnail is selected, together with the thumbnail.

[0024] Here, with reference to FIG. 2, a specific example of the display content will be described. FIG. 2 is a diagram showing an example of the display content according to the embodiment. Note that in FIG. 2, the display content is schematically shown, and a part of the thumbnail and the summary sentence is extracted and shown.

[0025] As shown in FIG. 2, the display content includes first display content P1 and second display content P2. FIG. 2 illustrates a case where thumbnails A1 and A2 are displayed as the first display content P1. Thumbnails A1 and A2 are thumbnails of different landing pages.

[0026] For example, the information processing apparatus 1 generates a summary sentence summarizing the content of the landing page for the thumbnail A1 whose thumbnail title is an interrogative sentence. For example, the information processing apparatus 1 generates a summary sentence summarizing the answer to the interrogative sentence based on the content of the landing page for the thumbnail that is an interrogative sentence. Note that the interrogative sentence includes a description in the form of a quiz.

[0027] For example, as a prompt in such a case, the information processing apparatus 1 inputs an instruction prompt such as "Please generate a sentence summarizing the answer to the thumbnail title from the content of the landing page" to the generation model.

[0028] Also, as shown in FIG. 2, a first expansion button B1 is displayed on the thumbnail A1 of the first display content P1. When the first expansion button B1 is selected by the user U, the second display content P2 is displayed on the user terminal 50.

[0029] As shown in FIG. 2, a summary sentence C1 summarizing the content of the landing page of the thumbnail A1 is displayed below the thumbnail A1. Here, as shown in FIG. 2, the summary sentence C1 is a part of the summary sentence.

[0030] That is, by displaying a part of the summary sentence together with the thumbnail A1, it is expected to arouse the user U's interest in the continuation of the summary sentence or the landing page. Also, as shown in FIG. 2, a second expansion button B2 is displayed on the summary sentence C1. When the user U selects the second expansion button B2, for example, the corresponding landing page is displayed on the user terminal 50.

[0031] In this way, by displaying the summary sentence C1 for the second display content P2, it can be expected to increase the user U's interest in the thumbnail A1, so that the click-through rate for the thumbnail can be improved.

[0032] [2. Information Processing Apparatus] Next, with reference to FIG. 3, a configuration example of the information processing apparatus 1 according to the embodiment will be described. FIG. 3 is a block diagram showing a configuration example of the information processing apparatus 1 according to the embodiment. As shown in FIG. 3, the information processing apparatus 1 includes a communication unit 2, a storage unit 3, and a control unit 4. Note that the information processing apparatus 1 may have an input unit (e.g., a keyboard, a mouse, etc.) that receives various operations from an administrator or the like who uses the information processing apparatus 1, and a display unit (e.g., a liquid crystal display, etc.) for displaying various information.

[0033] The communication unit 2 is realized by, for example, a NIC (Network Interface Card) or the like. The communication unit 2 is connected to a communication network such as 4G (4th Generation) or 5G (5th Generation) either wired or wirelessly, and transmits and receives information to and from each of the user terminals 50 and the like via the communication network.

[0034] The storage unit 3 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a storage device such as a hard disk or an optical disk. The storage unit 3 has a content storage unit 31 and a generation model storage unit 32.

[0035] The content storage unit 31 stores information related to the content. In the present embodiment, the information related to the content is information related to news articles distributed on news sites.

[0036] FIG. 4 is a diagram showing an example of information stored in the content storage unit 31 according to the embodiment. As shown in FIG. 4, the content storage unit 31 stores information on items such as "Content ID", "Category", "Thumbnail", and "LP (Landing Page)" in association with each other.

[0037] In the "Content ID" field, an identifier for identifying each piece of content is stored. In the "Category" field, information regarding the category of the corresponding content is stored. In this embodiment, since the content is a news article, information regarding the category of the news article is stored in the "Category" field.

[0038] In the "Thumbnail" field, a thumbnail of the content identified by the corresponding Content ID is stored. The thumbnail includes a thumbnail image and a title to be displayed as the thumbnail.

[0039] In the "LP" field, information regarding the landing page of the content identified by the corresponding Content ID is stored. The information regarding the landing page may be information regarding the text to be displayed on the landing page, or may be information regarding the link destination of the landing page.

[0040] Returning to the description of FIG. 3, the generation model storage unit 32 will be described. The generation model storage unit 32 stores a generation model. The generation model is a model that is learned to generate an answer for an input natural language sentence. The generation model can be realized by GPT.

[0041] Next, the control unit 4 will be described. The control unit 4 is a controller, and is realized, for example, by various programs (corresponding to an example of an information processing program) stored in a storage device inside the information processing apparatus 1 being executed with the RAM as a work area by a CPU (Central Processing Unit), an MPU (Micro Processing Unit), or the like. Further, the control unit 4 is, for example, a controller and is realized by an integrated circuit such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0042] As shown in FIG. 3, the control unit 4 includes a reception unit 41, a first generation unit 42, an acquisition unit 43, a second generation unit 44, and a provision unit 45, and realizes or executes the functions and operations of information processing described below. Note that the internal configuration of the control unit 4 is not limited to the configuration shown in FIG. 3, and may be any other configuration as long as it can perform the information processing described later. Also, the connection relationship between the respective processing units included in the control unit 4 is not limited to the connection relationship shown in FIG. 3, and may be any other connection relationship.

[0043] The reception unit 41 receives various requests from the user terminal 50. For example, the request includes a request for acquiring various contents for a news site. For example, the reception unit 41 receives a request including a user ID and information regarding the request type.

[0044] The first generation unit 42 generates primary content based on the request received by the reception unit 41. For example, the primary content is the content before generating the above-described display content, and is the normal content provided on the news site.

[0045] For example, the first generation unit 42 generates primary content by, in response to the request, posting an advertisement for a news article selected by the user U, or selecting a news article to be posted as a recommendation from the content storage unit 31.

[0046] The acquisition unit 43 acquires information on a thumbnail included in the content to be provided to the user terminal 50 and a landing page corresponding to the thumbnail. In the present embodiment, the acquisition unit 43 acquires the primary content generated by the first generation unit 42, and acquires information on a thumbnail included in the primary content and a landing page corresponding to the thumbnail.

[0047] Note that the acquisition unit 43 may, for example, acquire content (primary content) generated by another device, and acquire information on a thumbnail included in the content and a landing page corresponding to the thumbnail. That is, the generator of the primary content and the generator of the display content may be different operators.

[0048] When a sentence is input, the second generation unit 44 generates a summary sentence that summarizes the information on the landing page acquired by the acquisition unit 43 using a generation model learned to generate an answer for the sentence.

[0049] First, the second generation unit 44 extracts a thumbnail to be the target of summary sentence generation from among the thumbnails displayed in the primary content. For example, the second generation unit 44 extracts a thumbnail whose title is an interrogative sentence as the target of summary sentence generation.

[0050] The second generation unit 44 extracts, for example, a thumbnail whose title contains "?". Note that the extraction of the thumbnail may be performed using the generation model stored in the generation model storage unit 32.

[0051] For example, in this case, the second generation unit 44 inputs the title of the thumbnail displayed in the primary content and a prompt including an extraction instruction to the generation model. The extraction instruction is, for example, "Please extract the title that is an interrogative sentence from the following titles".

[0052] Subsequently, the second generation unit 44 generates a summary sentence that summarizes the information on the landing page for the extracted thumbnail. The second generation unit 44 inputs the information on the landing page of the thumbnail to be the target of summary sentence generation and a prompt including a summary instruction to the generation model.

[0053] The summary instruction is, for example, "Please summarize the answer to the following title from the content of the landing page", etc. Note that the summary instruction may include, for example, words such as "Please summarize so that the user wants to click on the thumbnail", and information regarding the attributes of the destination user may also be input to the generation model together. In such a case, a summary instruction such as "Please summarize so that a user with such attributes wants to click on the thumbnail" will be input together.

[0054] Based on these prompts, the generation model will generate a summary text and output the generated summary text. Note that as shown in FIG. 2, when it is assumed that a part of the summary text is to be displayed, a specification may be made such that the summary text has a certain number of characters or more. Also, the second generation unit 44 may generate summary texts for all thumbnails.

[0055] Then, the second generation unit 44 generates display content in which the generated summary text is associated with the corresponding thumbnail. For example, as shown in FIG. 2, on the thumbnail for which the summary text is generated, a first expansion button B1 is displayed, and when the first expansion button B1 is selected, a part of the summary text is displayed. Note that the second generation unit 44 may generate display content in which a part of the summary text is displayed from the beginning regardless of whether the first expansion button B1 is operated.

[0056] The providing unit 45 provides the display content generated by the second generation unit 44 to the user terminal 50 via the communication unit 2. The providing unit 45 will provide the display content to the user terminal 50 that is the source of the request received by the receiving unit 41.

[0057] 〔3. Processing Flow〕 Next, with reference to FIG. 5, the processing procedure executed by the information processing apparatus 1 according to the embodiment will be described. FIG. 5 is a flowchart showing an example of the providing process according to the embodiment.

[0058] As shown in FIG. 5, first, the information processing apparatus 1 generates primary content (step S101). Note that the primary content may be generated by another medium or the like. Subsequently, the information processing apparatus 1 acquires a thumbnail displayed in the primary content and information on the landing page (step S102).

[0059] Subsequently, the information processing apparatus 1 extracts a thumbnail to be a target for generating a summary sentence from among the thumbnails displayed in the primary content (step S103). For example, the information processing apparatus 1 extracts a thumbnail whose title is an interrogative sentence.

[0060] Subsequently, the information processing apparatus 1 generates a summary sentence that summarizes the content of the landing page for the extracted thumbnail (step S104), provides display content in which the summary sentence is displayed together with the thumbnail (step S105), and ends the process.

[0061] 〔4. Modification Example〕 Incidentally, in the above-described embodiment, the case where a summary sentence is displayed for a thumbnail displayed on a news site has been described, but the present invention is not limited thereto. For example, the present invention may be applied to thumbnails of a shopping site or the like, and the present invention may also be applied to advertisements displayed on various websites.

[0062] Further, the summary target of the summary sentence is not limited to the content of the landing page (for example, the news itself), and may include user comments or the like displayed on the landing page.

[0063] 〔5. Effect〕 The information processing apparatus 1 according to the above-described embodiment includes an acquisition unit 43 that acquires information on a thumbnail included in content provided to the user terminal 50 and a landing page corresponding to the thumbnail, and a generation unit (second generation unit 44) that generates a summary sentence summarizing the content of the landing page acquired by the acquisition unit 43 using a generation model trained to generate an answer to the sentence when the sentence is input, and a provision unit 45 that provides display content for displaying the summary sentence generated by the second generation unit 44 together with the corresponding thumbnail.

[0064] In addition, the provision unit 45 provides display content for displaying a part of the summary sentence together with the thumbnail. Further, the second generation unit 44 generates a summary sentence for thumbnails whose titles are interrogative sentences.

[0065] In addition, the second generation unit 44 generates a summary sentence including an answer to the interrogative sentence. Further, the provision unit 45 provides display content for displaying the summary sentence together with the thumbnail when an extension button set on the thumbnail is selected. Further, the second generation unit 44 generates a summary sentence using GPT (Generative Pre-trained Transformer) as the generation model.

[0066] By any one or combination of the above-described processes, the information processing apparatus according to the present application can improve the click-through rate for thumbnails.

[0067] 〔6. Hardware Configuration〕 In addition, the information processing apparatus 1 according to the above-described embodiment is realized by a computer 1000 having a configuration as shown in FIG. 6, for example. FIG. 6 is a hardware configuration diagram showing an example of a computer that realizes the functions of the information processing apparatus 1 according to the embodiment. The computer 1000 includes a CPU 1100, a RAM 1200, a ROM 1300, an HDD 1400, a communication interface (I / F) 1500, an input / output interface (I / F) 1600, and a media interface (I / F) 1700.

[0068] The CPU 1100 operates based on programs stored in the ROM 1300 or the HDD 1400 and controls each part. The ROM 1300 stores a boot program executed by the CPU 1100 when the computer 1000 is started up, programs dependent on the hardware of the computer 1000, and the like.

[0069] The HDD 1400 stores programs executed by the CPU 1100, data used by such programs, and the like. The communication interface 1500 receives data from other devices via a network (communication network) N and sends it to the CPU 1100, and sends data generated by the CPU 1100 to other devices via the network N.

[0070] The CPU 1100 controls output devices such as displays and printers, and input devices such as keyboards and mice (in FIG. 6, the output devices and input devices are collectively referred to as "input / output devices") via the input / output interface 1600. The CPU 1100 acquires data from the input devices via the input / output interface 1600. Further, the CPU 1100 outputs the generated data to the output devices via the input / output interface 1600.

[0071] The media interface 1700 reads a program or data stored in the recording medium 1800 and provides it to the CPU 1100 via the RAM 1200. The CPU 1100 loads such a program from the recording medium 1800 onto the RAM 1200 via the media interface 1700 and executes the loaded program. The recording medium 1800 is, for example, an optical recording medium such as a DVD (Digital Versatile Disc) or a PD (Phase change rewritable Disk), a magneto-optical recording medium such as an MO (Magneto-Optical disk), a tape medium, a magnetic recording medium, or a semiconductor memory.

[0072] For example, when the computer 1000 functions as the information processing apparatus 1 according to the embodiment, the CPU 1100 of the computer 1000 realizes the functions of the control unit 4 by executing the program loaded on the RAM 1200. The CPU 1100 of the computer 1000 reads and executes these programs from the recording medium 1800. As another example, these programs may be acquired from other devices via the network N.

[0073] As described above, some of the embodiments of the present application have been described in detail with reference to the drawings. However, these are merely examples, and the present invention can be implemented in other forms with various modifications and improvements based on the knowledge of those skilled in the art, including the aspects described in the column of the disclosure of the invention.

[0074] 〔7. Others〕 In addition, among the respective processes described in the above embodiments and modification examples, all or part of the processes described as being automatically performed can also be manually performed, or all or part of the processes described as being manually performed can be automatically performed by a known method. Additionally, regarding the processing procedures, specific names, and information including various data and parameters shown in the above documents and drawings, they can be arbitrarily changed unless otherwise specified. For example, the various information shown in each figure is not limited to the illustrated information.

[0075] Moreover, each component of each illustrated device is conceptually functional and does not necessarily need to be physically configured as shown in the drawings. That is, the specific form of the distribution and integration of each device is not limited to that shown in the drawings, and all or part of it can be functionally or physically distributed and integrated in any unit according to various loads, usage situations, etc.

[0076] Also, the above-described embodiments and modification examples can be appropriately combined within a range that does not conflict with the processing content.

[0077] In addition, the "section (section, module, unit)" described above can be read as "means", "circuit", etc. For example, the generation section can be read as a generation means or a generation circuit.
