(B2) The evaluation information acquired by the specified emotion category is classified.

  For example, in this embodiment, a plurality of buttons are provided that can be selected while viewing content such as “Like”, “Like”, “Nice”, “Looking”, “Cute”, etc. When a button is selected, the evaluation information registration processing unit 352 acquires a URL as data corresponding to each evaluation button as evaluation information. Then, the evaluation information registration processing unit 352 classifies the acquired evaluation information into the specified emotion category while specifying the emotion category corresponding to the acquired URL and showing the same evaluation as the evaluation button.

  Then, when the evaluation information registration processing unit 352 classifies the evaluation information into emotion categories as described above, the emotion category classified as evaluation information in the viewing management DB 333 in association with the viewing user ID and the viewing content ID. The emotion category information indicating is recorded.

[2.2.3] Recommendation Information Provision Processing Unit The recommendation information provision processing unit 353 performs a recommendation information provision process when a recommendation request for a recommendation target content is made by a recommendation request user.
(C1) a specific process for specifying a reference content and a specific emotion category,
(C2) a similar preference user detection process for detecting a similar preference user for each identified reference content;
(C3) In each specified reference content, similar preference content detection processing for detecting similar preference content for each detected similar preference user; and
(C5) The similar preference content having a predetermined condition is selected from the detected similar preference content, and each process of the providing process for providing the recommendation requesting user with information related to the selected similar preference content is executed.

(Specific processing)
The recommendation information provision processing unit 353 includes emotion category information to which the evaluation information registered by the recommendation requesting user belongs in each viewing content that has already been viewed by the recommendation requesting user (that is, the emotion in which the evaluation information is classified as described above). Category information), the viewing content is specified as the reference content, and the emotion category indicated by the corresponding emotion category information is specified as the specific emotion category.

  For example, when the evaluation information is stored for each content shown in FIG. 5 in the viewing management DB 333 and the recommendation requesting user is “user101”, the recommendation information provision processing unit 353 selects the reference content as the reference content. Each of “con001” to “con005” is specified, and emotion categories “nice (standard content con001)”, “cute (standard content con002)”, “cute (standard content con003)”, “ “Nice (reference content con004)” and “Nice (reference content con005)” are specified.

(Similar preference user detection processing)
The recommendation information provision processing unit 353 manages, for each identified reference content, another user different from the recommendation requesting user registered in association with the same emotion category information as the specific emotion category as a similar preference user. Detect from DB333.

  For example, when the evaluation information is stored in the viewing management DB 333 for each content shown in FIG. 5 and the recommendation requesting user is “user101”, the reference content is “con001” and the emotion category is “nice”. The recommendation information provision processing unit 353 detects three users “user102”, “user104”, and “user105” in which evaluation information “Nice” is registered for the content “con001” as similar preference users.

  Similarly, in the recommendation request user “user101”, the recommendation information provision processing unit 353 has an emotion category “cute” with respect to the reference content “con002”, and an emotion category “cute” with respect to the reference content “con003”, “ Similar preference users are detected for the emotion category “nice” for “con004” and the emotion category “nice” for the reference content “con005”.

(Similar preference content detection processing)
For each similar preference user detected in each specified reference content, the recommended information provision processing unit 353 is associated with the same emotion category that is different from the reference content and is the same as the specific emotion category. The registered content that the recommendation requesting user has not viewed is detected from the viewing management DB 333 as similar preference content.

  For example, evaluation information is stored for each content shown in FIG. 5 in the viewing management DB 333, the recommendation requesting user is “user101”, the reference content is “con001”, the emotion category is “nice”, and “user102” ”,“ User104 ”, and“ user105 ”are detected as similar preference users, the recommended information provision processing unit 353 is other than con001 and has similar preference users“ user102 ”,“ user104 ”, and“ user104 ”. “con002”, “con003”, “con004”, and “con005” registered as “nice” in the same emotion category in the user 105 are detected as similar preference contents.

  Similarly, the recommendation information provision processing unit 353 detects similar preference content for the other reference content and the emotion category corresponding thereto.

(Provision processing including selection processing)
The recommendation information provision processing unit 353 selects similar preference content having a predetermined condition from the detected similar preference content, and information on the selected similar preference content is referred to as a recommendation target content (hereinafter, “recommendation target content”). ) Is provided so that the recommendation requesting user can view the communication information to the communication terminal device 10 for viewing the similar preference content.

  In particular, the recommendation information provision processing unit 353 counts the number of users of similar preference users having the same specific emotion category for each similar preference content in the provision processing, and for each specific emotion category or for all specific emotion categories. , The similar preference content having the maximum count number or the upper count number determined in advance (for example, the top three), or the similar preference content having a predetermined value or more is similar preference content having a predetermined condition (that is, , Recommended content).

  Also, the recommendation information provision processing unit 353 relates to the recommendation target content such as the URL of each similar preference content selected as the recommendation target content, other information for viewing the content data of the similar preference content, or the content data itself. The information is acquired to generate recommendation information in a predetermined format such as an e-mail, and the recommendation information generated via the communication control unit 310 is provided to the communication terminal device 10 of the recommendation requesting user.

  Note that the recommendation information provision processing unit 353 may generate the recommendation information with the detected similar preference content as the recommendation target content without performing the selection process.

  For example, when “con002”, “con003”, “con004”, and “con005” are detected as similar contents in accordance with the example of FIG. 5, the recommended information provision processing unit 353 selects “con002”. The number of users is “3”, the number of users is “1” for “con003”, the number of users is “2” for “con004”, and the number of users is “1” for “con005”. It is recorded in the user number management DB 334 in association with the content ID of the content.

  In addition, the recommendation information provision processing unit 353 counts the number of counts in each specific emotion category or in all the specific emotion categories in the count results for all reference contents and emotion categories corresponding thereto recorded in the user number management DB 334. Is selected as the recommendation target content, and the recommended information in the selected recommendation target content is generated and provided.

  Further, the recommendation information provision processing unit 353 can select and display the URL of the content to be recommended in a specific emotion category as the recommendation information by specifying the recommendation requesting user, in the e-mail format or in the SNS's own web page. Information in a format posted at a predetermined location is generated, and the generated recommendation information is provided by e-mail or Web format.

(Example of recommendation information provision processing)
For example, as shown in FIG. 7, “photo of cherry blossoms”, “photo of cat”, “photo of sunflower”, and “article of birth of new smartphone (smartphone)” are stored in the content management DB 332 as contents. It is assumed that each content is viewed by “User A to User D” and evaluation information “Nice” or “Cute” is registered in the viewing management DB 333. In such a case, when a recommendation request for recommendation information is made by “user A”, the recommendation information provision processing unit 353 performs a specific process, a similar preference user detection process, a similar preference as follows. A providing process including a content detection process and a selection process is executed.

(1) Specific Processing When the recommended information provision processing unit 353 executes the specific processing with “User A” as the recommendation requesting user, the two contents of “cherry blossom photo” and “sunflower photo” are used as reference content 1 and reference content. In addition to specifying the content 2, the evaluation information of “nice” and “beautiful” is specified in the specific emotion category for each of the reference content 1 and the reference content 2.

(2) Similar preference user detection process for reference content 1 For “cherry blossom photo” of reference content 1, evaluation information “nice” is registered by “user B” and “user D”, and “user C” Since the evaluation information “cute” is registered by “”, the recommended information provision processing unit 353 registers “Nice”, which is the same specific emotion category, as “evaluation information for the same reference content” “User B” ”And“ user D ”are detected as similar preference users.

(3) Similar preference content detection processing for reference content 1 “Nice” evaluation information is registered by “user B” and “user D” for “cat photo” and “article of the birth of a new smartphone” Therefore, the recommended information provision processing unit 353 is a content that has already been viewed by a similar preference user, the same specific emotion category, and content different from the reference content, such as “cat photo” and “new model” "Smartphone birth article" is detected as similar preference content.

(4) Various Processes for Other Reference Content 2 The recommendation information provision processing unit 353 determines the recommendation target content for the reference content 2 based on the specific emotion category “nice” in the same manner. In the example of FIG. For the reference content “sunflower photos”, similar preference users are not detected, and therefore, similar preference content is also not detected.

(5) Selection processing In the reference content 1, for the similar preference content “cat photo”, “Nice” evaluation information is registered by both “User B” and “User D”, and “Birth of a new smartphone” Since the evaluation information of “nice” is registered only for “user D”, the recommended information provision processing unit 353 counts the number of users for “cat photo” as “2”, The number of users for the “new smartphone birth article” is counted as “1”.

  On the other hand, in the reference content 2, since there are no similar preference users and similar preference content, the recommendation information provision processing unit 353 does not count any content.

  Then, the recommendation information provision processing unit 353 specifies “a cat photo” having a high count as a recommendation target content for each specific emotion category or in all the specific emotion categories.

  Note that the recommendation information provision processing unit 353 does not count, but may specify both of the similar similar favorite contents specified as the recommendation target contents, or rank both contents according to the number of counts as the recommendation target contents. May be specified.

(6) Provision Processing The recommendation information provision processing unit 353 provides the “user A” with a URL that is information related to the specified recommendation target content so that the user can view the URL. Specifically, the recommended information provision processing unit 353 registers the personal user on the Web page when the “user A” receives the SNS service by the communication terminal device 10 or sets the email address of the “user A”. The recommended target content that has been transmitted is provided to the user “user A” of the recommendation request.

[3] Operation of Communication System [3.1] Evaluation Information Registration Process First, the evaluation information registration process of the communication system 1 will be described with reference to FIG. FIG. 8 is a flowchart showing the evaluation information registration process executed in the information providing system 1 of this embodiment.

  In this operation, it is assumed that the user has already registered the use of SNS, that is, the SNS user management DB 331 has recorded various information illustrated in FIG.

  Each user posts or reposts a comment indicating his / her evaluation together with a URL for viewing content such as an article, image or music that he / she likes, and the content management DB 332 includes, for example, FIG. It is assumed that various data necessary for each process of the operation shown in FIG.

  In addition, since the registration method for using the SNS and the method for posting the content are the same as those of the conventional SNS, the detailed description of the operation is also omitted. In this operation, it is assumed that the communication terminal apparatus 10 is waiting for an input to be performed on an operation unit (not shown) while displaying a login instruction to the SNS by a user on a display unit (not shown).

  First, when the communication terminal device 10 detects an input operation related to viewing of content and registration of evaluation information performed by the user via the operation unit (step Sa100), the communication terminal device 10 instructs the information providing server device 30 about the specific content. A viewing request is transmitted, and reception of data for viewing the specified content is awaited (step Sa101).

  At this time, the communication terminal device 10 transmits, for example, a request for viewing various contents posted or reposted by another user such as a friend to the information providing server device 30 while maintaining the login state.

  The method of specifying the viewing content by the user is arbitrary. For example, a list including the content IDs of the content posted by the friend or reposted as “Recent activity of friend” or the like is transmitted from the information providing server device 30 to the communication terminal. Provided to apparatus 10. Then, the communication terminal apparatus 10 causes the user to select content to be viewed (hereinafter also referred to as “viewing content”) from the provided list, and a content ID corresponding to the selected viewing content. May be added to the viewing request and transmitted.

  Next, in the information providing server device 30, when the SNS management unit 351 receives the viewing request transmitted from the communication terminal device 10 via the communication control unit 310 (step Sa200), the SNS management unit 351 designates the viewing request from the content management DB 332. Various types of data related to the viewing target content are read out, transmitted to the communication terminal device 10 through the communication control unit 310 so that the user can view the viewing target content, and reception of evaluation information is awaited (step Sa201).

  At this time, the SNS management unit 351 transmits data for enabling viewing of the viewing target content including the URL and other posting user and viewing user comments to the corresponding communication terminal device 10.

  Next, when the communication terminal device 10 receives the data for viewing the viewing target content transmitted by the information providing server device 30 (step Sa102), the comments of the posting user and other viewing users based on the received data Display, playback or display and playback of the corresponding viewing content including, and wait for input of evaluation information (step Sa103).

  Next, when the user detects a comment input or input of evaluation information such as selection of a predetermined evaluation button (step Sa104), the communication terminal apparatus 10 transmits the detected evaluation information to the information providing server apparatus 30. (Step Sa105), this operation is terminated.

  In the process of step Sa105, when the communication terminal apparatus 10 detects an input of a comment, it transmits evaluation information including a character string corresponding to the input comment, and detects selection of a predetermined evaluation button. In the case, evaluation information including information (for example, URL) indicating the evaluation button is transmitted.

  Further, the communication terminal device 10 may link with the information providing server device 30 after transmitting the evaluation information, confirm the transmitted evaluation information, or make a viewing request for other viewing content. When making a viewing request for other viewing content, the communication terminal apparatus 10 proceeds to the process of step Sa101.

  Furthermore, when the communication terminal device 10 detects an operation different from the input operation of the evaluation information in the process of step Sa104, the operation based on the input operation detected by ending this operation without executing the process of step Sa105. Is supposed to start.

  Next, in the information providing server device 30, when the SNS management unit 351 receives the evaluation information via the communication control unit 310 (step Sa202), the evaluation information registration processing unit 352 includes text data in the received evaluation information. It is determined whether it has been (step S203). However, when the SNS management unit 351 receives another request transmitted from the same communication terminal device 10, the SNS management unit 351 stops the subsequent processing and ends this operation.

  At this time, if the evaluation information registration processing unit 352 determines that the received evaluation information includes text data, the evaluation information registration processing unit 352 performs a predetermined process such as morphological analysis on the text data to extract a keyword. While (step Sa204), the extracted keyword is compared with a dictionary prepared in advance to determine the emotion category to which the keyword belongs (step Sa205), and the process proceeds to step Sa207.

  When the evaluation information registration processing unit 352 determines that the received evaluation information does not include text data, the evaluation information includes information corresponding to the evaluation button. The emotion category corresponding to the evaluation button is determined (step Sa206), and the process proceeds to step Sa207. For example, when the evaluation button corresponds to the evaluation “Nice”, the evaluation information registration processing unit 352 determines “Nice” as the emotion category.

  Next, the evaluation information registration processing unit 352 registers the evaluation information together with the viewing content and the viewing user in the viewing management DB 332 together with the emotion category information indicating the determined emotion category (step Sa207), and ends this operation. Let

  As described above, by executing the evaluation information registration process, in the information providing system 1 according to the present embodiment, the evaluation information by the viewing user who has viewed the content is recorded in the viewing management DB 333.

  Specifically, the recommended information provision processing unit 353 searches the viewing management DB 333 based on the user information of the login user, and the emotion category to which the registered evaluation information belongs in each viewing content that has already been viewed by the login user. While acquiring information, each of the viewing contents is specified as the reference content, and the emotion category indicated by the corresponding emotion category information is specified as the specific emotion category. In addition, the recommendation information provision process part 353 specifies a specific emotion category for every viewing content, when there exist several viewing content (namely, reference | standard content).

  Next, for each identified reference content, the recommended information provision processing unit 353 detects similar preference users based on the specific emotion category and the content viewing record of other users recorded in the viewing management DB 333 (step Sb202). .

  Next, for each reference content, the recommended information provision processing unit 353 detects similar preference content based on the specific emotion category, the detected similar preference user, and its evaluation information (step Sb203).

  Next, for each reference content, the recommended information provision processing unit 353 counts the number of similar preference users who are registered with evaluation information belonging to the specific emotion category for one detected similar preference content. Store in the management DB 334 (step Sb204).

  Next, the recommendation information provision processing unit 353 selects a recommendation target content based on the count number for each similar preference content stored in the user number management DB 334 and a predetermined condition (step Sb205), and the recommendation target content The recommendation information corresponding to is generated (step Sb206).

  Next, the recommendation information provision processing unit 353 provides the recommendation information generated to the communication terminal device 10 of the recommendation requesting user (Step Sb210), and ends this operation.

  Next, when receiving the recommendation information (step Sb102), the communication terminal device 10 displays the received recommendation information so as to be viewable to the user (step Sb103), and ends this operation. Note that the communication terminal device 10 displays or reproduces (that is, views) the recommendation target content recommended in accordance with a user operation based on the displayed recommendation information.

  As described above, in the information providing system 1 according to the present embodiment, similar preferences that are assumed to have the same sensibility as the recommendation requesting user by detecting other users evaluated with the same emotion for the same content. A user can be specified, and unviewed content evaluated by the same emotion as the emotion when the similar preference user evaluated the same content is detected from the content viewed by the similar preference user in the past. Therefore, it is possible to specify unviewed content that is assumed that the income-desiring user has the same feeling as the similar preference user.

  Therefore, the information providing system 1 can recommend and provide unviewed content that assumes the feelings of the recommendation requesting user by mediating a user having a preference similar to that of the recommendation requesting user.
