[0012] (Embodiment) Hereinafter, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a system configuration diagram showing an example of the configuration of an information processing system SYS according to an embodiment of the present invention. The information processing system SYS of the present invention includes an information processing device 10, a social network service server 20, and a user terminal 30. The information processing device 10, the social network service server 20, and the user terminal 30 are connected via a network so as to be able to communicate with each other.

[0013] The information processing system SYS acquires post-related data by users, extracts user data linked to the post-related data, extracts one or more keywords from the post-related data, and generates correlation data indicating a correlation between the user data and the keywords. The information processing system SYS also acquires a keyword selected by the user from one or more keywords as a search term, and generates presentation information in which the search term and one or more user data related to the search term are associated with the degree of relevance to the search term.

[0014] The information processing system SYS also includes a user data extraction unit that acquires user post related data and extracts user data associated with the post related data, and extracts one or more keywords from the post related data to generate correlation data indicating the correlation between the user data and the keywords. The information processing system SYS also acquires a user selected from icons representing one or more user data as a search target, and generates presentation information that associates the search target with one or more keywords related to the search target and the degree of relevance to the search target.

[0015] Here, the post-related data refers to text data posted by a user to a social network service and channel data registered by a user in a social network service. A channel is information that indicates attributes of a community or the like. The presented information is a correlation diagram in which the degree of association between a search term and one or more users is represented by connecting lines connecting the search term to each icon representing one or more users, or a correlation diagram in which the degree of association between a search target and one or more keywords related to the search target is represented by connecting lines connecting the icon of the search target to each icon representing one or more keywords.

[0016] The information processing device 10 acquires post data posted by a user from the social network service server 20 via a network. The post data includes text data and image data posted by the user, channel data registered by the user, and user data of the user who posted the data. The information processing device 10 extracts keywords and user data from the posted data. Keywords are also called hot keywords or trend words, and are keywords that are frequently posted by a large number of users at a certain point in time. The information processing device 10 extracts user data who posted the extracted keywords from the posted data, and generates correlation data that associates the keywords with the user data.

[0017] The information processing device 10 also presents the extracted keywords to the user and allows the user to select a keyword to be used as a search term from the keywords. The information processing device 10 acquires the selected keyword as a search term, and generates user data corresponding to the search term as presentation information by referring to the correlation data. The information processing device 10 transmits the generated presentation information to the user terminal 30 via a network.

[0018] The social network service server 20 is a server device that operates a social network service. The social network service server 20 accepts and publishes posts from users. The social network service server 20 transmits post data to the information processing device 10 via an API and a network. The social network service may be a communication service that allows information sharing, chatting, and the like.

[0019] The user terminal 30 is a terminal device used by a user, such as a tablet, a smartphone, a PC, etc. The user terminal 30 is connected to the information processing device 10 and the social network service server 20 via a network.

[0020] Next, the configuration of the information processing device 10 will be described.

[0021] FIG. 2 is a block diagram showing an example of the configuration of the information processing device 10 according to the present embodiment. The information processing device 10 includes a communication unit 11, a storage unit 12, an input unit 13, an output unit 14, and a control unit 15. The communication unit 11 has a function of communicating with the social network service server 20 and the user terminal 30. The communication unit 11 outputs various information received from the social network service server 20 and the user terminal 30 to the control unit 15. In addition, the communication unit 11 transmits various information output from the control unit 15 to the social network service server 20 and the user terminal 30.

[0022] The memory unit 12 is configured with a storage medium, for example, a hard disk drive (HDD), a flash memory, an electrically erasable programmable read only memory (EEPROM), a random access read / write memory (RAM), a read only memory (ROM), or any combination of these storage media. The storage unit 12 may be, for example, a non-volatile memory.

[0023] The storage unit 12 stores various data. For example, the storage unit 12 stores post data 121, keyword data 122, correlation data 123, and user data . The post data 121 is the post data acquired from the social network service server 20 . Keyword data 122 is data on keywords extracted by control unit 15 from the posting data. The correlation data 123 is data in which a keyword, user data, channel data registered by a user, and the degree of relationship (correlation) between them are associated with each other. The user data 124 is data in which contact information such as a user's email address and telephone number, and user identification information are associated with each user.

[0024] The input unit 13 is an input device such as a mouse or a keyboard connected to the information processing device 10. The input unit 13 accepts an operation input input from the outside. The input unit 13 outputs an operation signal to the control unit 15 according to the operation input.

[0025] The output unit 14 is an output device such as a display device, etc. The output unit 14 outputs the presentation information output from the control unit 15 to the output device or another device such as the user terminal 30.

[0026] The control unit 15 has a function of controlling each unit of the information processing device 10. The control unit 15 includes a post data acquisition unit 151 , a keyword extraction unit 152 , a user extraction unit 153 , a correlation data generation unit 154 , a search term acquisition unit 155 , and a presentation information generation unit 156 .

[0027] The post data acquisition unit 151 acquires the post related data from the social network service server 20 via the communication unit 11 and the network. The post data acquisition unit 151 stores the acquired post related data as post data 121 in the storage unit 12.

[0028] The keyword extraction unit 152 reads out the posted data 121 from the storage unit 12, analyzes the posted data, and extracts one or more keywords. The keywords are ranked based on the number of times they appear, the number of times they are repeated (frequency), etc. The keyword extraction unit 152 stores keyword data representing the extracted keywords in the storage unit 12. Moreover, the keyword extraction unit 152 outputs keyword data representing the extracted keywords to the user extraction unit 153 .

[0029] When keyword data is input from keyword extraction unit 152, user extraction unit 153 extracts user data of users who have posted content including the keyword from the posting data stored in storage unit 12. The user data also includes information on the number of times (frequency) each user has posted the keyword as a degree of association with the keyword. User extraction unit 153 stores the extracted user data in storage unit 12. Furthermore, the user extraction unit 153 outputs the extracted user data to the correlation data generation unit 154 .

[0030] When the correlation data generating unit 154 receives user data from the user extracting unit 153, the correlation data generating unit 154 generates correlation data in which the user and the keyword are associated with each other. The correlation data includes the correspondence between the user and the keyword, a numerical value indicating the degree of association (degree of correlation) between the user and the keyword, and, for example, the number of times the keyword is posted by the user. The correlation data generating unit 154 also extracts registered channels for each user from the posting data, and generates correlation data in which the user and the registered channel are associated with each other. The correlation data generating unit 154 stores the generated correlation data in the storage unit 12.

[0031] The search term acquisition unit 155 reads out the keyword data 122 from the storage unit 12, and presents one or more read keywords to the user as search term candidates. The search term acquisition unit 155 acquires a keyword selected by the user from the presented search term candidates as a search term. The search term acquisition unit 155 outputs information representing the acquired search term to the presentation information generation unit 156.

[0032] The search term acquisition unit 155 may read out the user data 124 from the storage unit 12, and present the users represented by the one or more pieces of read out user data to the user as search target candidates. In this case, the search term acquisition unit 155 may output to the presentation information generation unit 156 the user data representing the search target selected by the user from the presented search target candidates.

[0033] When information representing a search term is input from the search term acquisition unit 155, the presentation information generation unit 156 reads out user data from the storage unit 12. The presentation information generation unit 156 extracts user data of a user associated with the search term from the read user data, and generates presentation information. The presentation information includes information representing a correlation between a keyword and a user, and a degree of correlation between the keyword and the user. In addition, the correlation data generation unit 154 extracts data on channels to which the user is subscribed from the posting data stored in the memory unit 12, and generates presentation information that associates the user, the channel, and the degree of association between the user and the channel. The presentation information generating unit 156 outputs the generated presentation information to the output unit 14.

[0034] When a user representing a search target is input from the search term acquisition unit 155, the presentation information generation unit 156 may read keyword data from the storage unit 12, extract keyword data associated with the search target from the read keyword data, and generate presentation information. The presentation information includes information representing a correlation between a keyword and a user, and a degree of correlation between the keyword and the user.

[0035] Next, the keywords, the relationship between the keywords and the user data and the degree of the relationship, and the relationship between the user data and the channel and the degree of the relationship will be described.

[0036] FIG. 3 is a diagram showing an example of keywords extracted by the information processing device 10 according to the present embodiment. The information processing device 10 extracts one or more keywords from the posting data stored in the storage unit 12. In the illustrated example, the information processing device 10 extracts keyword data representing multiple keywords such as "keyword A", "keyword B", "keyword C", "keyword D", "keyword E", "keyword F", "keyword G", etc. from the posting data. When the user selects one or more of these multiple keywords, the selected keyword is set as a search term.

[0037] As shown in the figure, multiple keywords may be presented in different display formats depending on the number of times they appear in the posted data, their frequency of appearance, etc., so that a keyword that appears frequently is presented in a display format that is more emphasized than other keywords, such as "keyword G."

[0038] FIG. 4 is a correlation diagram showing an example of the relationship and the degree of relationship between keywords and user data according to this embodiment. 3, for example, a correlation diagram showing the relationship and the degree of relationship between the keyword and the user data displayed when the user selects "keyword G" as a search term from among search term candidates is shown. The correlation diagram is generated by the information processing device 10 as presentation information. In the illustrated example, "AA", "BB", "CC", "DD", "EE", "FF", and "GG" are, for example, icons representing users. The keywords and the icons representing the users are connected by connecting lines. The connecting lines indicate that the keywords and the users are related to each other. The thickness of the connecting lines indicates the degree of relatedness between the keywords and the users. For example, a thicker connecting line indicates a higher degree of relatedness between the keywords and the users than the degree of relatedness represented by a thinner connecting line.

[0039] FIG. 5 is a correlation diagram showing an example of the relationship and the degree of relationship between user data and channels according to the present embodiment. FIG. 5 is displayed when the user selects the icon "AA" in FIG. 4. In the illustrated example, the degree of association between the user and the channel is shown. In the illustrated example, "AAA", "BBB", "CCC", and "DDD" represent channels to which the user "AA" is subscribed. The icon representing the user "AA" and the icon representing the channel are connected by a connecting line. The connecting line represents that the user and the channel are associated. The thickness of the connecting line represents the degree of association between the user and the channel. For example, the thicker the connecting line, the higher the degree of association between the user and the channel is represented compared to the degree of association represented by a thinner connecting line.

[0040] In this way, the information processing device 10 can check the relevance and degree of relevance between keywords and users, and the relevance and degree of relevance between users and channels based on the posting data by selecting a search term from search candidates, thereby enabling the user to obtain the search results desired.

[0041] Next, an example of information processing according to the present embodiment will be described.

[0042] FIG. 6 is a flowchart showing an example of information processing in the information processing device 10 according to the present embodiment. In step S101, the information processing device 10 acquires post data from the social network service server 20 via the communication unit 11 and the network. After that, the information processing device 10 executes the process of step S102.

[0043] In step S102, the information processing device 10 extracts keywords from the posted data. After that, the information processing device 10 executes the process of step S103.

[0044] In step S103, the information processing device 10 extracts user data of the user who posted the content including the keyword extracted in step S102 from the posted data. After that, the information processing device 10 executes the process of step S104.

[0045] In step S104, the information processing device 10 generates correlation data that associates users with keywords and indicates the degree of association between the keywords and the users. After that, the information processing device 10 executes the process of step S105.

[0046] In step S105, the information processing device 10 presents one or more keywords as search term candidates to the user, and acquires the search term candidate selected by the user as the search term. After that, the information processing device 10 executes the process of step S106.

[0047] In step S106, the information processing device 10 generates presentation information indicating the relevance and degree of relevance between the search term and the user. Then, the information processing device 10 ends the information processing related to Fig. 6. Note that in step S106, the information processing device 10 may execute the processing of step S102 by using the generated presentation information as post data.

[0048] As such, the information processing system SYS of this embodiment includes a post related data acquisition unit (post data acquisition unit 151) that acquires post related data posted by users, a user data extraction unit (user extraction unit 153) that extracts user data linked to the post related data, a keyword extraction unit 152 that extracts one or more keywords from the post related data, a correlation data generation unit 154 that generates correlation data indicating the correlation between the user data and the keywords, a search term acquisition unit 155 that acquires a keyword selected by the user from one or more keywords as a search term, and a presentation information generation unit 156 that generates presentation information that associates the search term and user data of one or more users related to the search term with the degree of relevance to the search term.

[0049] In this way, the user can select a search term from the presented keywords, improving user convenience. In addition, the user can check users related to the selected search term and the degree of relevance of the users, so that the user can obtain the search results he or she desires.

[0050] In the information processing system SYS, the post-related data is text data and image data posted by the user, and channel data subscribed to by the user.

[0051] In this way, search term candidates can be appropriately extracted.

[0052] In addition, in the above-mentioned information processing system SYS, the presented information is a correlation diagram in which the degree of association between a search term and one or more users is represented by connecting lines connecting the search term and each icon representing the one or more users.

[0053] In this way, the user can visually confirm the correspondence between the search term and the search results that he or she desires, thereby improving convenience for the user.

[0054] Moreover, the information processing system SYS according to this embodiment includes a post related data acquisition unit (post data acquisition unit 151) that acquires post related data posted by users, a user data extraction unit (user extraction unit 153) that extracts user data linked to the post related data, a keyword extraction unit 152 that extracts one or more keywords from the post related data, a correlation data generation unit 154 that generates correlation data indicating the correlation between the user data and the keywords, a search target acquisition unit (search term acquisition unit 155) that acquires a user selected from icons representing one or more of the user data as a search target, and a presentation information generation unit that generates presentation information that associates the search target and one or more keywords related to the search target with the degree of relevance to the search target.

[0055] In this way, it is possible to improve convenience for users because keywords and channels associated with each user can be checked. Also, since keywords and channels can be searched for from each user, the user can obtain the search results he or she desires.
