Description

[Technical Field]

[0001] The present disclosure relates to a program, an information processing device, and a method. [Background technology]

[0002] In services that provide electronic books, there are techniques for improving the accuracy of book searches to make it easier for users to find the information they are looking for. For example, there is a technology that "includes a category database formed by storing categories created by artificial means in association with category keywords belonging to the categories, a keyword input means that allows a user to input any keyword, a search of the category database to find categories associated with the category keyword corresponding to the keyword input by the user using the keyword input means, and displays the categories found by the search on the display device" (Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2010-049372 Summary of the Invention [Problem to be solved by the invention]

[0004] While the above technologies can search for e-books that fit a category, theme, etc., based on a search term, they have a problem in that it is difficult for users to find information on a specific topic they want to know about related to the search term. For example, information on a topic requires more specific description, so simply assigning a category to an e-book does not tell users whether the information is actually specific or where in the e-book it is. As a result, the above technology has the problem that users cannot easily find information on a topic. The purpose of the present disclosure is to allow users to easily access information easily. [Means for solving the problem]

[0005] The technology disclosed herein is a program for operating a computer, wherein a memory unit of the computer stores issue information including an issue and a portion of a book related to the issue, and the program causes a processor of the computer to execute the steps of accepting input of an issue to be searched for from a user, identifying a portion related to the accepted issue based on the accepted issue and the issue information, and presenting the accepted issue and the portion related to the issue to the user. [Effects of the Invention]

[0006] The techniques of the present disclosure can provide users with easy access to information related to a topic. [Brief explanation of the drawings]

[0051] The identifying unit 134 identifies a portion related to the received issue based on the received issue and issue information.

[0052] Specifically, the identification unit 134 first searches the issue ID of the received issue from the issue information DB 123. For example, the identification unit 134 uses the received issue as a search keyword and searches for the issue ID of an issue that includes the search keyword. The identification unit 134 may perform the search using a trained model that has been trained to output issues that match the search keyword when the search keyword is input. Alternatively, the identification unit 134 may convert the search keyword and the issue stored in the issue information DB 123 into feature vectors, calculate the distance between the feature vectors, and determine the issue IDs of issues whose distance is shorter than a predetermined threshold as search results.

[0053] Next, the identification unit 134 identifies the portion related to the issue by referring to the issue portion DB 121. Specifically, the identification unit 134 references the issue portion DB 121 to extract the book ID corresponding to the searched issue ID and the section in the book where the portion related to the issue is described. The identification unit 134 extracts the extracted book ID and the section where the portion related to the issue is described from the book data of the book corresponding to the book ID by referring to the book information DB 122. The identification unit 134 also extracts information about the book corresponding to the book ID. The book information includes, for example, the book title, cover image, publisher, etc.

[0054] The identification unit 134 may also identify a portion related to the received issue based on transition information including the issue, the issue information, and books or portions within the books that other users have viewed after the portion related to the issue was identified. Specifically, the identification unit 134 refers to the user information DB 124 to acquire transition information of searched issues that match the issue of the other users. The identification unit 134 then identifies the portion related to the issue based on the portion related to the issue in the issue portion DB 121 and the transition information of the other users. For example, the identification unit 134 may identify both the portion related to the issue identified from the issue portion DB 121 and the portion related to the issue identified from the transition information of the other users as the portion related to the issue. For example, the identification unit 134 may also identify the portion most frequently described in the transition information of the other users as the portion related to the issue. The identification unit 134 may also refer to the user information DB 124 and, if the portion is the same as an issue previously searched by the user, identify the portion related to the issue based on the transition information of the user.

[0055] Furthermore, the identifying unit 134 refers to the user information DB 124 to identify an issue related to the retrieved issue ID.

[0056] Furthermore, upon receiving the selected related issue from the user terminal 20, the identification unit 134 identifies the portion related to the selected related issue. Specifically, the identification unit 134 refers to the issue portion DB 121 to extract the book ID corresponding to the related issue and the portion in the book where the portion related to the related issue is described. The identification unit 134 extracts the portion related to the related issue from the book data of the book corresponding to the book ID by referring to the book information DB 122 for the extracted book ID and the portion where the portion related to the issue is described. Furthermore, the identification unit 134 extracts information about the book corresponding to the book ID.

[0057] The presentation unit 135 presents the accepted points of contention and parts related to the points of contention to the user.

[0113] In this modification, the input unit 133 receives input of a search word as a topic to be searched for from the user.

[0114] In this modification, the identification unit 134 searches for an issue based on the search word and the issue information. Specifically, the identification unit 134 first searches for an issue that includes the received search word from the issue information DB 123. The identification unit 134 sets the search results as candidates for the issue.

[0115] In this modification, the presentation unit 135 presents candidate issues to the user. Specifically, the presentation unit 135 presents the candidate issues to the user by transmitting them to the user terminal 20. In this way, the information processing device 10 receives from the user a selection of an issue that the user wishes to search for from the candidate issues.

[0116] In this modification, when the identification unit 134 receives a candidate for the selected issue from the user terminal 20, it identifies a part related to the selected issue.

[0117] The process in the second modification is executed, for example, after step S805 in the above embodiment.

[0118] 13 is a diagram showing an example of a screen that presents potential points of discussion. As shown in FIG. 13, a screen 1300 includes a text box 1001, a button 1002, and a presentation section 1301.

[0119] The presentation unit 1301 presents candidate points of discussion. The presentation unit 1301 is configured to accept selection of candidate points of discussion. When a candidate point of discussion is clicked, tapped, or the like by a user operation, the user terminal 20 transmits the selected candidate point of discussion to the information processing device 10.

[0120] When the candidate points of contention are transmitted to the information processing device 10, the identifying unit 134 identifies the parts related to the points of contention.

[0121] According to the second modification, the user can easily access information about the issue by specifying the issue that the user wants to search for from among candidate issues based on search words.

[0122] The presentation unit 135 may display candidate points of contention based on the user's attributes. For example, the storage unit 120 also stores attributes of the points of contention. Attributes of the points of contention include, for example, the major categories of legal points of contention and economic points of contention, the medium categories of civil law, criminal law, administrative law, intellectual property law, and the like, and the small categories of civil law and criminal law. The presentation unit 135 changes the display mode of the candidate points of contention according to the user's attributes. For example, if the user's attribute is the legal department, the presentation unit 135 preferentially displays candidate legal points of contention.

[0123] Alternatively, candidate points of discussion may be displayed for the search word entered in the text box 1001. In this case, the user terminal 20 executes a process for determining whether a search word has been entered in the text box 1001, and transmits the search word to the information processing device 10 at the timing when the search word is entered. Then, when the information processing device 10 receives the candidate points of discussion, the user terminal 20 displays a presentation unit 1301 immediately below the text box 1001. In this case, the user can specify the point of discussion they want to search for before clicking the button 1002, etc., and the user can more easily access information about the points of discussion.

[0124] (Other variations) The information processing device 10 may also be configured to automatically update the user information DB 124 by storing information about books, parts of books, and the like that the user has viewed after searching for a topic in the user information DB 124.

[0125] The information processing device 10 may also be configured to accept an evaluation of a portion of a book related to a point of discussion from a user. For example, the information processing device 10 accepts an evaluation of the completeness of the description of the point of discussion. The information processing device 10 calculates the completeness of the description of the point of discussion in the book based on the accumulated completeness evaluations. Then, when there are multiple portions related to the point of discussion, the presentation unit 135 presents the portion with the highest completeness to the user. This allows the user to easily access information related to the point of discussion.

[0126] The information processing device 10 may also extract trending issues using the history of searched issues. The information processing device 10 presents the extracted trending issues to publishers, authors, etc. This allows the publishers, authors, etc. to know that there is a need for the currently sought-after issues.

[0127] Furthermore, the information processing device 10 may use the history of searched issues to extract a ranking of the number of times books have been viewed for each issue. The information processing device 10 presents the user with a ranking of the number of times books have been viewed for each issue. When the user clicks on a book listed in this ranking, the information processing device 10 allows the user to view the book. This allows the user to easily access information related to the issues without having to search.

[0128] The information processing device 10 may also be configured to display recently searched topics according to the user's attributes. For example, the information processing device 10 may display to the user a message such as "These topics have been searched recently," thereby presenting a plurality of recently searched topics according to the user's attributes. For example, the information processing device 10 may present topics that have been searched for within a specified period of time by users with the same attributes as the user's attributes stored in the user information DB 124. When the user clicks on a topic, the information processing device 10 presents the user with a ranking of the number of times books on the topic have been viewed. When the user clicks on a book listed in this ranking, the information processing device 10 allows the user to view the book. This allows the user to easily access information related to the topic without having to search for it.

[0129] The information processing device 10 may also be configured to present categories of issues to the user, and identify portions related to the issues by the user selecting a category. The categories may be, for example, broad categories such as legal issues and economic issues, medium categories such as civil law, criminal law, administrative law, and intellectual property law, and narrow categories such as civil law and criminal law. The information processing device 10 first displays a broad category, and when a user selects one, it then displays a medium category, and finally accepts the user's selection of an issue. The identification unit 134 may then identify portions related to the arguments for the selected issue. This allows users to easily access information about the issues without having to perform tedious manual input.
