This information providing system 1 has an information providing device 10 . The information providing device 10 is a computer device (server), and has a function of providing information that supports the creation and improvement of sentences that are easy for readers to understand. That is, the destinations to which the information providing apparatus 10 provides information are, for example, companies, public bodies, etc. (hereinafter also referred to as service providers). The information providing device 10 prepares or improves the text presented (output) by the service provider to the user of the service provided by the service provider so that it is easy for the reader to understand as described above. Provide information that will assist you in doing so. In the following description of the embodiments, a sentence to which information is provided by the information providing apparatus 10 is also called a target sentence. Specific examples of target sentences include privacy policies, terms of use, instructions, and articles for disseminating information related to provided services.

The information providing device 10 is connected via an information communication network 3 such as the Internet to an information processing device (computer device) on the text output side (service provider) that outputs such target text. Companies and public organizations that output target sentences often have a plurality of information processing apparatuses. As a result, the information processing device that outputs the target text may be different from the information processing device that is connected to the information providing device 10, but here, a plurality of information processing devices on the text output side are collectively referred to as a text output device. 30. In the example of FIG. 1, the information providing apparatus 10 is connected to only one text output side (service provider), but the information providing apparatus 10 can be connected to a plurality of text output sides. Information can be provided to a plurality of text output sides (service providers).

For example, assume that the terminal device 20 receives a text to be supported from the text output device 30 . Here, it is assumed that the text to be supported that the terminal device 20 receives from the text output device 30 is the same as the text to be supported that the text output device 30 receives information from the information providing device 10 . For this reason, in the following description, both the supported text received by the terminal device 20 from the text output device 30 and the supported text received by the text output device 30 from the information providing device 10 are referred to as target text. It is assumed that

When the terminal device 20 receives the target text from the text output device 30 and the user activates the support application, the terminal device 20 extracts the keyword to be extracted from the target text by the support application. Then, the terminal device 20 transmits the extracted keyword to the information providing device 10 in a form associated with the user identification information that identifies the user. Upon receiving the keyword, the information providing device 10 searches the storage device for support information that meets the search conditions including the keyword and the user's attributes, and returns the support information to the terminal device 20 . Here, a keyword is a term or phrase that is considered important in understanding the target sentence, and information on the keyword to be extracted from the target sentence is determined in advance and given to the terminal device 20 . Further, the support information is information that supports understanding of the target sentence, and includes, for example, sentences, diagrams, and photographs explaining the keyword, and information introducing articles related to the keyword. An article related to a keyword is, for example, a news article that became a topic related to the keyword. Examples of the information introducing the article include text data of the article itself and a URL (Uniform Resource Locator) specifying the site on the Internet where the article is published.

The terminal device 20 that has received the support information displays the support information on the screen of the display device 21 in a predetermined display mode. The displayed support information is useful for resolving the user's unclear points and concerns about the target text. can agree with the matters described in the subject document. In other words, the information providing system 1 can solve the situation in which the user agrees to the target sentences such as the terms of use and the privacy policy without understanding them.

The configuration of the information providing system 1 in the first embodiment will be described below. FIG. 3 is a block diagram showing a simplified configuration of the information providing device 10 and the terminal device 20. As shown in FIG.

27 and 28 as shown in FIG. The received information is transmitted to the information providing apparatus 10 as user's intention information. When transmitting the intention information, the intention information is associated with the user identification information and the sentence identification information.

Furthermore, the transmission unit 52 transmits to the information providing device 10 the user registration information entered by the user when starting to use the support application. That is, here, when the user uses the support application for the first time, the input form for user registration is displayed on the display device 21 . The user registration input form is a template that includes input fields for registering user information (registered name (for example, nickname), contact information such as e-mail address, etc.) in the information providing system 1 .

In addition, in the first embodiment, the user registration input form includes a questionnaire (hereinafter also referred to as a questionnaire at the time of registration) for surveying items of interest to the user. This registration questionnaire is provided from the information providing device 10, for example. The questionnaire at the time of registration includes a plurality of questions about whether or not there is an interest in news articles that are related to the target text and have become a hot topic. An appropriate number of questions may be set in consideration of the user's response load. In addition, the answer to the question of whether or not there is an interest may be in the form of a two-choice answer, such as whether or not there is (Yes or No), or the degree of interest may be divided into multiple levels. It is not limited, as it may be an answer format in which the degree is selected.

When the user inputs an instruction to the terminal device 20 to transmit the information input in the user registration input form including the questionnaire at the time of registration to the information providing device 10, the transmission unit 52 The received information is transmitted to the information providing device 10 .

The receiving unit 53 receives the support information transmitted from the information providing device 10. As described above, the support information is information that assists in understanding the target text. For example, the support information introduces text, diagrams, and photographs explaining the keyword extracted by the extraction unit 51, or articles related to the keyword. Contains information.

The receiving unit 53 also receives an update questionnaire sent from the information providing device 10 by, for example, push notification. The update questionnaire is a questionnaire for surveying items of interest to the user at predetermined timings (for example, once a month). For example, an update questionnaire is generated during the period between the timing of sending the update questionnaire and the timing before that, and whether or not the user is interested in the topic related to the content of the target sentence questions are included. The number of questions in the questionnaire for updating may be one or plural.

The presentation unit 54 displays the support information received by the reception unit 53 from the information providing device 10 on the display device 21 in a predetermined display mode. FIG. 4 is a diagram illustrating an example of a display mode of support information. In the example of FIG. 4, in the target sentence displayed on the display device 21, a mark 25 is displayed that clearly indicates the keyword associated with the received support information. When the mark 25 is indicated, the support information associated with the keyword corresponding to the indicated mark 25 is popped up. In addition, in the example of FIG. 4, the terminal device 20 is a smart phone or a tablet, and the display device 21 is equipped with a touch panel. Therefore, in the example of FIG. 4, the mark 25 displayed on the display device 21 is indicated by the finger of the user. Indicated by the cursor by manipulation. Thus, the method of indicating the mark 25 is not limited. Also, the method of clearly indicating the keyword associated with the received support information is not limited to the method of displaying a mark, and may be, for example, a method of using the color of characters representing the keyword or the background color of the characters. .

FIG. 5 is a diagram explaining another example of the display mode of the support information. In the example of FIG. 5, the screen of the display device 21 is provided with a column for displaying support information separately from the column in which the target sentence is described, and the support information is displayed in this column. A line or the like connecting the support information and a keyword related to the support information is also displayed.

When the presentation unit 54 displays a URL as support information, the terminal device 20 has a function of connecting to the site of the URL when the displayed URL is specified. This allows the user to easily refer to the URL site.

The investigation unit 55 of the computing device 22 investigates what the user is interested in. For example, the research unit 55 determines whether text data representing articles such as news acquired via the information communication network 3 includes a predetermined research keyword. Then, when the research unit 55 determines that the research keyword is included, the research unit 55 pops up a question asking whether the browsed article interests the user (Yes or No). Furthermore, when the answer to the question is input, the research unit 55 transmits interest information including the answer to the information providing device 10 . The interest information includes, for example, all or part of the text data (for example, title and headline) of the article that is the subject of the question corresponding to the answer, the date and time of the answer, and the user identification information associated with the answer. included. Note that the timing of transmitting the interest information may be every preset period, or may be when the interest information is accumulated and the accumulated number reaches a predetermined number.

Also, upon receiving the update questionnaire via the receiving unit 53, the investigation unit 55 displays on the display device 21 a notification indicating that the update questionnaire has been received. Then, when the user requests the display of the update questionnaire, the research unit 55 displays the update questionnaire and accepts responses to the update questionnaire. Further, the research unit 55 associates the user identification information with the information representing the answer to the update questionnaire, and transmits the information of the answer to the update questionnaire to the information providing device 10 .

The terminal device 20 is configured as described above. Next, the configuration of the information providing device 10 will be described.

The information providing device 10 includes an arithmetic device 11 and a storage device 12, as shown in FIG. The storage device 12 includes storage media for storing data and computer programs (programs) 48 . There are multiple types of storage devices such as magnetic disk devices and semiconductor memory devices, and there are multiple types of semiconductor memory devices such as RAM (Random Access Memory) and ROM (Read Only Memory). As such, there are many types. The type of storage device 12 included in the information providing device 10 is not limited to one. Computer devices are often equipped with multiple types of storage devices. Here, the type and number of storage devices 12 provided in the information providing device 10 are not limited, and the description thereof is omitted. Also, when the information providing apparatus 10 is provided with a plurality of types of storage devices, they are collectively referred to as a storage device 12 .

One of the programs stored in the storage device 12 is a program for causing the information providing device 10 to execute the process of providing information on the target sentence.

In addition, the storage device 12 stores text output side information and user information. The text output side information is information about the text output side (service provider) such as a company or public organization that outputs the target text to be supported. The text output side information includes service provider identification information that identifies the service provider, text identification information that identifies the text output by the service provider, and contact information for contacting the service provider. is The user information is information about the user who receives the support information for assisting the understanding of the target sentence, and is for each user based on the information entered in the user registration input form transmitted from the terminal device 20. generated. The user information includes, for example, user identification information, contact information, and attribute information. As described above, the user identification information is information that identifies the user. The contact information is information representing a contact to contact the user, such as an e-mail address. The contact information may include contact means information in a communication tool other than e-mail.

Attribute information is information that represents a user's attributes.

Here, we will explain the attributes of users. The information providing device 10 transmits support information corresponding to the user when returning the support information, which is information for supporting the understanding of the target sentence, to the terminal device 20 . A user's attribute is information referred to when determining the support information to be transmitted. be. As a specific example, if the target sentence is a sentence of a privacy policy, attributes based on the extent and degree of user interest in personal information can be considered. FIG. 6 is a table showing an example of attributes of the user. In the example of FIG. 6, "A" represents "countermeasures and guarantees when personal information is leaked." "B" represents "measures against leakage of personal information". "C" represents "other information related to leakage of personal information (for example, misuse of leaked personal information, etc.)".

Users are somewhat interested in "A (handling and guarantees in case personal information is leaked)" (degree of interest is "low"), but about "B" and "C" regarding personal information is of little interest. The attribute of the user in this case is attribute "1-1", referring to FIG. It is also assumed that the user has some interest in personal information "A" and "B" (the degree of interest is "small"), but little interest in "C". The attribute of the user in this case is attribute "1-2". Furthermore, it is assumed that the user has a strong interest in all of "A", "B", and "C" regarding personal information (the degree of interest is "high"). The attribute of the user in this case is attribute "3-3".

In the example shown in FIG. 6, the number of attributes is nine, but the number of attributes is not limited as long as it is plural. It may be appropriately set in consideration of the type and number of available information. In addition, when setting attributes, humans may decide, for example, using sample data of a large number of users, including the relationship between the breadth of interest and the degree of interest, using AI (Artificial Intelligence) clustering technology Attributes may be set.

The storage device 12 of the information providing device 10 further stores the user's usage history. The user's usage history is history information that indicates the usage status of each user. For example, sentence identification information that indicates the target sentence using this system and information on the date and time of use are associated with the user identification information. It is In addition, if the target text includes items that require consent, such as a privacy policy, the user's usage history will also include information on whether or not they have agreed to the target text. .

The storage device 12 further stores support information. As described above, the support information is information that is transmitted to the terminal device 20 and supports the understanding of the target sentence. The support information is stored in the storage device 12 in association with the corresponding keyword and attribute information, as shown in FIG. In addition, here, the support information may be appropriately updated according to changes in social conditions and public opinion. Moreover, it is considered that the content of the support information required by the user differs depending on the attributes of the user (that is, the range of interests that the user has and the degree of that interest). Considering this, the combination of the user's attribute and the content of the support information is determined.

Furthermore, the storage device 12 stores the above-described registration questionnaire (questionnaire conducted when a user is registered) to be transmitted to the terminal device 20 . This registration questionnaire may also be appropriately updated in accordance with changes in social conditions, public opinion, etc., in the same manner as described above.

In addition, the storage device 12 also stores the above-described renewal questionnaires to be sent to the terminal device 20 .

In addition, the storage device 12 stores attribute determination data. The attribute determination data is data that is referred to when determining a user's attribute from responses to a registration questionnaire or an update questionnaire. AI (Artificial Intelligence) technology may be used to determine the attribute of the user. In this case, for example, a model generated by machine-learning the relationship between information about the extent and degree of interest of the user and the attributes of the user is stored in the storage device 12 as attribute determination data.

Information such as text output side information, user information, and support information is stored not in the storage device 12 provided in the information providing device 10 but in an external storage device (database) to which the information providing device 10 can be connected. ) 14. In this case, the information providing device 10 is appropriately connected to the storage device 14 to read and write text output side information, user information and support information.

The computing device 11 is composed of a processor such as a CPU (Central Processing Unit). The computing device 11 can have various functions based on the program 48 by reading and executing the program 48 stored in the storage device 12 . Here, the computing device 11 includes, as functional units related to information provision, a receiving unit 41, a determining unit 42, a searching unit 43, a transmitting unit 44, an updating unit 45, a tallying unit 46, and a providing unit 47. have.

The receiving unit 41 receives information transmitted from the terminal device 20 . The information received by the receiving unit 41 from the terminal device 20 includes keywords extracted from the target text, positive opinions such as agreeing with the matters described in the target text, and negative opinions such as disagreeing. There is intention information that indicates whether The received intention information is stored in the storage device 12 in association with the user information, for example. Further, the information received by the receiving unit 41 includes user registration information, answers to update questionnaires, interest information, and the like.

The determination unit 42 determines the attribute of the user. For example, upon receiving an answer to a questionnaire at the time of registration via the receiving unit 41 , the determination unit 42 uses the answer to the questionnaire and attribute determination data in the storage device 12 to determine the attribute of the user. The attribute information of the user determined by this determination is stored in the storage device 12 as one of the information constituting the user information as described above.

In addition, in this embodiment, since it is assumed that the extent of user interest and the degree of interest change over time, the information providing device 10 has a function of updating user attribute information.

That is, the update unit 45 sends the above-described update questionnaire (questionnaire for investigating items of interest to the user) to the terminal device 20 at predetermined timings (for example, once a month) by, for example, push notification. Send (output). As for topics used for questions in the questionnaire for updating, information on the topic may be manually input to the information providing apparatus 10, or articles such as news containing preset extraction terms may be extracted by the information providing apparatus 10. and may be used for updating questionnaire questions.

When the determination unit 42 receives an answer to such an update questionnaire via the reception unit 41, for example, it reads attribute information of the user who answered the update questionnaire from the storage device 12. Then, the determination unit 42 re-determines the attribute of the user who answered the update questionnaire by using the attribute information, the question contents of the update questionnaire, and their answers. Then, the determination unit 42 updates the attribute information of the user information stored in the storage device 12 to the attributes based on the re-determination.

Furthermore, even when the interest information is received from the terminal device 20 via the reception unit 41, the determination unit 42 reads out the user attribute information related to the interest information from the storage device 12, and reads the attribute information and the attribute information. , and the interest information are used to re-determine the attributes of the user associated with the interest information. Then, the determination unit 42 updates the attribute information of the user information stored in the storage device 12 to the attributes based on the re-determination.

In addition, it is assumed that users will not respond to questionnaires for renewal and questions to investigate their interests because they find it troublesome. As a countermeasure against this, for example, each time a user answers a questionnaire for renewal or a question that investigates their interests, by giving points that can be exchanged for a gift, etc., the user is provided with an incentive to answer. It may be provided in the system 1. If it is considered unnecessary to update the user's attribute information based on the contents of the target text, etc., the function to update the user's attribute information in the information providing system 1 is May be omitted.

Upon receiving the keyword extracted from the target sentence from the terminal device 20 via the receiving unit 41, the searching unit 43 searches the storage device 12 for support information related to the keyword. Here, instead of searching by keyword alone, a combination of the keyword and user attribute information specified from the user information in the storage device 12 using the user identification information associated with the keyword is used. Support information is retrieved using the retrieval conditions. In other words, since it is assumed that the necessary support information differs depending on the user's attributes (the range of interests that the user has and the degree of their interest), the search for support information that takes into account the user's attributes is executed.

For example, suppose that the keyword is "third party" as shown in FIG. 7 and the user's attribute is "2-1". In this case, the keyword (term) explanation and the URL specifying the site where the online article related to the keyword is described are searched as the support information by the search condition of the combination of the keyword and the user's attribute. It is retrieved from the storage device 12 by the unit 43 .

The sending unit 44 sends back the support information searched by the searching unit 43 to the terminal device 20 that has output the keyword.

Based on the intention information received from the terminal device 20, the aggregation unit 46 aggregates the consent status in the target sentence. That is, for each target sentence, the counting unit 46 calculates the total number of users (terminal devices 20) who have received support information for the sentence, the number of people who have given consent (number of consenters), and the consent rate. In addition, the tallying unit 46 collects the number of people who did not agree (the number of people who did not agree), the rate of disagreement, and the number of people who did not express their intention of agreeing or not Calculate the number of abandoned people: the number of abandoned people) and the abandonment rate. Note that the agreement rate is the ratio of the number of people who agree with the total number of users (terminal devices 20) who have received support information regarding the same target sentence. The disapproval rate is the ratio of the number of disapproved users to the total number of users (terminal devices 20) who have received support information regarding the same target sentence. Furthermore, the abandonment rate is the ratio of the number of abandoners to the total number of users (terminal devices 20) who have received support information regarding the same target sentence. Note that the counting unit 46 may, for example, calculate at least the agreement rate, the disagreement rate, and the abandonment rate, and may not calculate the abandonment rate.

In addition, the aggregation unit 46 may aggregate the consent status for each target sentence and further for each attribute. Furthermore, the information on the results of aggregation by the aggregation unit 46 is stored in the storage device 12 in association with information such as the date and time of aggregation so that the information on the chronological change in the consent status, which is the aggregation result by the aggregation unit 46, can be acquired from the storage device 12. Stored.

The tallying unit 46 executes such tallying processing at preset time intervals (for example, starting at 2:00 am every Monday), and newly adds the tallying results stored in the storage device 12. Update the aggregation result by adding the calculated aggregation result. Note that the timing of executing the counting process may be set as appropriate. For example, the number of users of the information providing apparatus 10 is counted for each target sentence instead of for each set time interval, and the number of users is, for example, set The aggregation process may be executed each time the value is increased by 100. In addition, when the number of users per unit period in the information providing apparatus 10 varies greatly depending on the target sentence, the timing of executing the tallying process may be changed for each target sentence.

Regarding the aggregation result of the consent status by the aggregation unit 46 as described above, when the support information is transmitted to the terminal device 20, the aggregation result of the consent status for the target sentence corresponding to the support information is also transmitted by the transmission unit 44 to the terminal device 20. It may be sent to device 20 . In this case, the terminal device 20 also has a function of displaying information on the result of counting by the counting unit 46 using the support application. For example, in the terminal device 20, when a consent sentence, which is a target sentence, is displayed,

icons

27 and 28 for inputting information as to whether to agree or not are displayed as shown in FIG. , the information of the totalization result by the totalization unit 46 is displayed. Note that when a plurality of pieces of information can be displayed as the tallied result, an icon or the like that enables selection of information to be displayed may be displayed on the display device 21 of the terminal device 20 . By displaying the aggregate results in this way, when the user decides whether or not to agree with the target text (for example, the privacy policy), the information of the aggregate results displayed (that is, the intention status regarding consent of others ) can be referenced.

The providing unit 47 outputs (provides) the aggregate result of the aggregate processing by the totalizing unit 46 regarding the target sentences output by the sentence output side (text output device 30). The timing at which the provision unit 47 provides the aggregated result of the aggregation process by the aggregation unit 46 depends on the needs of the text output side (service provider), such as once a month. body) may be set. Note that, as described above, the aggregating unit 46 collects a plurality of data, such as the agreement rate and disagreement rate for each target sentence, the agreement rate and disagreement rate for each attribute of each target sentence, and their time-series data. Species tallies can be calculated. The type of totalized result provided by the providing unit 47 to the text output side (text output device 30) may be determined according to the needs of the text output side. In addition, depending on the needs of the document output side, depending on the type of aggregation results, for example, the consent rate and disagreement rate are provided once a month, and the time series data is provided once a year. The provision frequency of the aggregated results provided to the text output side by the provision unit 47 may be different. The setting information of the types of totalized results provided to the text output side by the provision unit 47 and the frequency of provision is included in the text output side information in the storage device 12 (storage device 14), for example.

Further, when providing the tally result of the tallying process by the tallying unit 46, the providing unit 47 provides the content of the information provided to the terminal device 20 as support information for each target sentence according to the needs of the sentence output side. Information to be notified may be output to the text output side (text output device 30).

Furthermore, the providing unit 47 may provide reference information introducing topical news articles or similar sentences related to the target sentence to the sentence output side (text output device 30). The reference information is, for example, information hit by the providing unit 47 from a site on the Internet that publishes news articles, etc., using predetermined search terms and phrases related to the target sentence. . Alternatively, the reference information provided by the providing unit 47 to the text output side (text output device 30) may be information manually saved in the information providing device 10, for example. The timing at which the providing unit 47 provides the reference information may be adjusted to the timing at which the aggregate result is provided, or may be set when the number of unprovided reference information reaches a predetermined number.
