It may be any content that can be distributed to the device 100. That is, any information can be applied to the information distributed by the information distribution device 10 as long as the information is distributed based on the user's log.

[1-2. About history information]
Next, the history information will be described. The history information is an arbitrary log associated with the user, for example, a target log. For example, the history information may include a user history, which is a log showing the history of searches and browsing sites performed by the user on the Web, a log showing that a material request has been made for an arbitrary product, and the like. .. Further, in the history information, for example, whether or not various contents have been browsed, whether or not the contents have been selected such as being tapped, and a link from a predetermined web page to the web page on which the contents and contents are arranged are set. Information such as whether or not it may be included. In addition, the history information includes a log indicating whether or not the content was searched using a web search engine or the like, and whether or not information about the content was transmitted (tweet, etc.) by a short message service or a microblog. It may be.

Here, the history information includes a service on the Internet such as SNS (Social Networking Service), the fact that various information about the user is registered at an actual store, and the content of the registered information. For example, history information includes not only information such as name, age, gender, address, annual income, work place, work department, and work content, but also information such as music and movie titles that the user is interested in. Shall be. That is, the history information includes not only the history of user actions that can be acquired through the Internet, but also information input by the user through the Internet.

In addition, the history information includes various information related to the hardware used by the user to browse various contents. For example, the history information includes device information indicating the type of the terminal device 100, such as the IP (Internet Protocol) address assigned to the terminal device 100 used by the user to browse the contents, the model name and model number of the terminal device 100, and the like. , System information indicating an OS (Operating System) operating on the terminal device 100 and an application program, and the like are included.

[1-3. Information distribution device 10]
The information distribution device 10 is an information processing device realized by a server device, a cloud system, or the like. The information distribution device 10 is communicably connected to the terminal device 100 used by the user U01 and the terminal device 101 used by the user U03 via a network N (for example, the Internet or the like) (not shown).

The terminal device 100 is an information processing device used by the user U01, and is used for the user to browse information. To give a specific example, the terminal device 100 includes a smartphone, a tablet terminal, a mobile terminal such as a PDA (Personal Digital Assistant), a desktop PC (Personal Computer), a notebook PC, and the like.

Here, when the information is distributed to each user, the information presumed to be of interest to the user is selected based on the history information of the user to whom the information is distributed, and the selected information is distributed. Conceivable. However, the history information may include a history based on the user's personal hobbies and interests (hereinafter, may be referred to as personal history) and a history of the user's social behavior (hereinafter, may be referred to as social history). .) Is mixed. Therefore, when information to be distributed is selected simply based on the user's behavior history, information that the user is not personally interested in is presumed to be information that the user is personally interested in. There is a risk that it will end up.

Therefore, the information distribution device 10 executes the following information distribution processing. First, the information distribution device 10 executes a specific process for identifying a user belonging to a common social group. Subsequently, the information distribution device 10 executes a selection process for selecting information to be provided to other users belonging to a social group common to the specified user, based on the behavior history of the specified user. After that, the information distribution device 10 distributes the selected information to the user.

[1-4. About specific processing]
Hereinafter, the specific processing and the selection processing executed by the information distribution device 10 will be specifically described. First, the specific process executed by the information distribution device 10 will be described. First, the information distribution device 10 identifies a user who belongs to a common organization that actually exists and a user who has a predetermined human relationship as a user who belongs to a common social group. For example, the information distribution device 10 is a reality such as a user belonging to a group having a social relationship in the real world such as a common company, a common department, a common group, a family, or a circle as a common social group. Identify users belonging to a common organization that exists in as a common social group. Further, for example, the information distribution device 10 is used for social actions, ideas, and purposes of users having a predetermined blood relationship such as parents, brothers, sisters, relatives, and friends, lovers, spouses, partners, and the like. , Users having a predetermined human relationship, such as users having a predetermined commonality in tastes, etc., are specified as users belonging to a common social group.

Here, any method can be applied to the method for identifying the user to which the information distribution device 10 belongs to a common social group. For example, the information distribution device 10 may identify users belonging to a common social group based on the commonality of information related to the hardware used by each user. That is, the information distribution device 10 may identify users belonging to a common social group based on the name identification result of information related to the hardware used by each user.

For example, when accessing the Internet from the same company, the same department, the same home, etc., it is predicted that an IP address having a common whole or domain is assigned to the hardware. Therefore, the information distribution device 10 may identify users belonging to a common social group based on the commonality of IP addresses included in the action history. For example, the information distribution device 10 may specify a plurality of users who use hardware to which the same IP address is assigned as users belonging to the same home or the same company. Further, the information distribution device 10 may specify a plurality of users who use hardware to which IP addresses of the same domain are assigned as users belonging to the same company or the same department.

In addition, users belonging to the same company or users belonging to the same department may be provided with the same type of hardware or hardware in which the same version of OS or application is installed. Therefore, the information distribution device 10 collects type information indicating at least one of the type of hardware used by each user and the type of a program such as an OS or an application executed by the hardware, and the collected type information. Users who belong to a common social group may be identified based on the commonality of.

Further, the information distribution device 10 may specify users belonging to a common social group based on the commonality of type information indicating a combination of a hardware type and a software type. For example, the information distribution device 10 uses a predetermined message digest function to calculate a hash value of device information and system information included in an action history as a fingerprint (FP: Finger Print). Then, the information distribution device 10 may specify a user belonging to the same department based on the calculated name identification result of the fingerprint.

Further, the information distribution device 10 may identify users belonging to a common social group based on the commonality of at least one of the history of contents browsed by each user and the information registered in advance by the user. Good. For example, the information distribution device 10 selects users belonging to a common company or department based on the browsing history of business-oriented contents such as a schedule management web page, an in-house bulletin board system, a company SNS, and a registration-based information retrieval system. It may be specified.

Further, the information distribution device 10 may identify users belonging to a common social group based on information on work places and departments posted by each user on SNS and the like, information on circles and families, and the like. For example, the information distribution device 10 uses a predetermined API (Application Programming Interface) to collect information on work places and departments registered by each user, names, family information, etc. from various SNSs, and uses the collected information as information. Based on this, users who belong to a common social group may be identified.

Further, the information distribution device 10 may specify a user belonging to a common social group by appropriately combining the above-mentioned information, and identifies a user belonging to a common social group by using information other than the above-mentioned information. You may. For example, the information distribution device 10 has a common social address for each user because of common IP addresses, common fingerprints, common browsing history of business contents, common information registered in advance by each user, and the like. A score belonging to a group may be calculated, and a plurality of users whose calculated score value is higher than a predetermined threshold value may be specified as users belonging to a common social group.

That is, the information distribution device 10 does not group a plurality of users having a common gender or age, but has a plurality of users (for example, having a common purpose or interest) presumed to have a predetermined relationship in the real world. Users belonging to a group) are identified as users belonging to a common social group. It should be noted that the information distribution device 10 can use a plurality of users who are predicted to belong to a common social group with a certain degree of certainty without specifying users who belong to an absolutely common social group. It may be specified as a user belonging to the group.

[1-5. About selection process]
Next, the selection process executed by the information distribution device 10 will be described. For example, the information distribution device 10 extracts the behavior history of a user belonging to a predetermined social group by a specific process. Then, the information distribution device 10 selects information to be provided to other users belonging to a predetermined social group based on at least one of the commonality and the non-commonality of the extracted behavior history.

For example, among the behavior histories of a plurality of users belonging to a common social group, the common behavior history is the interest that each user has as a social group, that is, the purpose and interest of the social group (hereinafter collectively referred to as interest interest). It is predicted that it shows. On the other hand, among the behavior histories of a plurality of users belonging to a common social group, the behavior histories that are not common are expected to indicate the personal interests of each user. Therefore, the information distribution device 10 sets the fields of information that the social group is interested in and the fields of information that each user is personally interested in, based on the commonality or non-commonality of the behavior history of each user. Identify.

For example, if the behavior history of the first user includes a log indicating that the music-related website and the travel-related website are frequently visited, and belongs to the same department as the first user. It is assumed that the behavior history of the identified second user includes a log indicating that the movie-related website and the travel-related website are frequently visited. In such a case, the log common to both, that is, the log indicating that the travel-related website is frequently browsed, for example, searches for a comfort travel destination in the department to which the first user and the second user belong. It can show that it is. That is, it can be said that the log indicating that the travel-related website is frequently browsed is information indicating that the interest of the department to which the first user and the second user belong is related to travel.

On the other hand, among the behavior histories of the first user, the behavior history that is not common to the behavior history of the second user, that is, the log indicating that the first user has browsed the music-related website is for the music-related information. It can be said that this is information indicating that the user has a personal interest. In addition, among the behavior histories of the second user, the behavior history that is not common to the behavior history of the first user, that is, the log indicating that the second user has browsed the movie-related website is for the movie-related information. It can be said that the information indicates that the person has a personal interest.

Therefore, the information distribution device 10 is interested in a common social group to which each user belongs, based on at least one of commonality and non-commonality between the behavior history of the first user and the behavior history of the second user. The action history showing the personal interest of each user and the action history showing the personal interest of each user are extracted. Then, the information distribution device 10 selects the information to be provided to each user based on the extracted action history.

For example, the information distribution device 10 estimates the interests of the first user based on the non-commonality of the behavior history of the first user and the behavior history of the second user, and based on the estimated interests, Information to be provided to the first user may be selected. Then, the information distribution device 10 may distribute the selected information to the terminal device 100 used by the first user.

For example, the information distribution device 10 may distribute the selected information to the terminal device 100 used by the second user as information indicating the interest of the first user. For example, the information distribution device 10 displays the selected information as information indicating the interest of the first user, such as "The first user seems to be interested in this." It may be displayed on the terminal device 100 used by the user.

Further, the information distribution device 10 extracts a common behavior history from the behavior history of the first user and the behavior history of the second user, and uses the extracted behavior history to belong to a common society to which each user belongs. Select information that is presumed to be of interest to the target population. Then, the information distribution device 10 distributes the selected information to the first user and the second user. In the information distribution device 10, when the third user belongs to a common social group together with the first user and the second user, the social group is interested in the third user. Information that is presumed to be possessed may be delivered.

Further, the information distribution device 10 is an action history having commonality among the action history of the first user and the action history of the second user, and does not have commonality with the action history of the third user. Information to be provided to the third user may be selected based on the action history. Further, in the information distribution device 10, for example, even if there is no commonality between the behavior history of the first user and the behavior history of the second user and the behavior history of the third user, each user If they belong to a common social group, information selected based on the commonality of the behavior history of the first user and the behavior history of the second user may be distributed to the third user. Further, even if the behavior history of each user is not common, the information distribution device 10 can use the information selected based on the behavior history of the first user as long as each user belongs to a common social group. It may be delivered to a second user and a third user.

That is, if the information distribution device 10 selects information to be distributed based on the behavior history of each user belonging to a common social group, the information distribution device 10 can obtain information that is presumed to be of interest to the social group. You may choose, or you may choose information that is presumed to be of personal interest to each user belonging to that social group. Further, the information distribution device 10 may distribute the selected information to any user as long as it provides the selected information to the users belonging to the social group. For example, the information distribution device 10 is used not only for users who used the action history when selecting information, but also for users who did not use the action history when selecting information and users who do not have common behavior history with other users. , The selected information may be delivered.

Further, the information distribution device 10 identifies a plurality of users belonging to the first social group and a plurality of users belonging to the second social group, and the action history of each user belonging to the first social group. The interests of the first social group may be estimated based on the commonality of the above, and the information to be provided to the users belonging to the second social group may be selected based on the estimated interests. That is, the information distribution device 10 may provide information selected based on the behavior history indicating the interests of the social group to which each user belongs to the users belonging to other social groups.

Further, the information distribution device 10 may select information to be provided to each user based on the role of each user in the social group. For example, when the first user and the second user belong to a common social group such as a family, if the first user is a user who has a conversion such as a husband, the second user is personal. Information that is presumed to be interested in may be delivered to the first user. For example, the information distribution device 10 may notify the husband of information on a product or property that the wife is presumed to be personally interested in. Further, the information distribution device 10 may notify the manager of a certain department of the information of the comfort travel destination searched by the subordinates, and notifies the subordinates of the department of the information of the travel destinations that only the manager frequently accesses. You may.

Further, the information distribution device 10 may change the information to be distributed according to the user to whom the information is distributed. Specifically, when the first user selects the information provided to the first user, the information distribution device 10 is the same type of information as the distributed information but different in content. May be selected as information to be provided to a second user who belongs to a social group common to the first user. For example, when a child of a family selects an advertisement for a game, the information distribution device 10 may deliver an advertisement for the game and an advertisement with a link to a purchase page to the parents of the family. Good.

[1-6. An example of information distribution processing]
Next, an example of the information distribution process executed by the information distribution device 10 will be described with reference to FIG. In the following description, the information distribution device 10 includes real estate information related to real estate, travel information related to travel, cosmetic information related to cosmetics, food information related to food, music information related to music, movie information related to movies, etc. as information to be distributed. , Information C10 to be distributed shall be retained. Further, the information C10 is assumed to be an advertisement, for example.

First, the information distribution device 10 identifies a plurality of users (hereinafter, may be referred to as a group) belonging to a common social group from a plurality of users (step S1). For example, in the example shown in FIG. 1, four users U01 to U04 are specified as users belonging to the group G01. Subsequently, the information distribution device 10 calculates the commonality and non-commonality of the action histories of the users U01 to U04 of the group G01 (step S2).

For example, in the example shown in FIG. 1, a diagram conceptually showing the action history L01 of the user U01, the action history L02 of the user U02, the action history L03 of the user U03, and the action history L04 of the user U04 is described. Here, in the example shown in FIG. 1, it is assumed that a part of each action history L02 to L04 overlaps with each other, and the action history L01 does not overlap with other action histories L02 to L04.

Here, among the action histories L02 to L04, the range S01 having similar or overlapping contents is predicted to indicate the interest of the group G01 as a whole. Further, among the action histories L03, the range S02 that does not overlap with the other action histories L02 and L04 is predicted to indicate the personal interest of the user U03. Therefore, the information distribution device 10 selects information to be distributed to each user U01 to U04 based on the calculation results of the commonality and non-commonality of the action histories L01 to L04 of each user U01 to U04 (step S3).

Then, as shown in FIG. 1A, the information distribution device 10 selects the information C01 presumed to satisfy the interests of the group G01 based on the action history included in the range S01. For example, the information distribution device 10 selects real estate information, travel information, and the like as information C01 to be distributed based on the action history included in the range S01.

Further, as shown in FIG. 1B, the information distribution device 10 selects information C02 presumed to satisfy the personal interests of the user U03 based on the action history included in the range S02. For example, the information distribution device 10 selects cosmetic information, movie information, and the like as information C02 to be distributed based on the action history included in the range S02.

Then, the information distribution device 10 distributes the selected information C01 and C02 to the users U01 to U04 of the group G01 (step S4). For example, the information distribution device 10 uses the information C01 selected based on the action history included in the range S01 as the user U01 among the users U01 to U04 included in the group G01 whose action history does not overlap with the range S01. It is transmitted to the terminal device 100. That is, although the information distribution device 10 belongs to the group G01, the information that the users U02 to U04 have a common interest in the user U01 whose interest is different from that of the other users U02 to U04. That is, users U02 to U04 can notify information that is of social interest. The information distribution device 10 may distribute the information C01 to all the users U01 to U04 included in the group G01. For example, the information distribution device 10 may distribute the information C01 only to the users U02 to U04 whose action history includes the range S01. , Information C01 may be delivered.

Further, the information distribution device 10 distributes the information C02 selected based on the action history included in the range S02 to the terminal device 101 used by the user U03. As a result, the information distribution device 10 can distribute the information C02, which is presumed that the user U03 is personally interested, instead of the information that the user U03 is socially interested in. The information distribution device 10 may distribute the information C02, which is presumed to be personally interested by the user U03, to the users U01, U02, and U04 together with the fact that the user U03 is personally interested. Further, the information distribution device 10 specifies, for example, an action history having the largest range similar to or overlapping with the action history L03 of the user U03, and the user U03 is interested in the user corresponding to the specified action history. The estimated information C02 may be delivered.

Further, in the information distribution device 10, the users U02 and U03 are interested in the information selected based on the part that does not overlap with the range S01 among the common parts of the action history L02 of the user U02 and the action history U03 of the user U03. As the information to have, it may be distributed to the user U01 or the user U04. In this way, the information distribution device 10 may select information to be distributed based on the action history obtained by an arbitrary calculation mode.

[1-7. About calculation]
In the above-described example, the information distribution device 10 selects the information C01 and C02 to be distributed based on the calculation results of the commonality and non-commonality of the action histories L01 to L04. Here, the information distribution device 10 may select information to be distributed by an arbitrary calculation method. For example, the information distribution device 10 individually uses the action histories L01 to L04 of each user U01 to U04 to obtain a score indicating the strength of interest that each user U01 to U04 has for each field of information to be distributed. A field in which the score value is higher than a predetermined value may be specified as a field of information in which the group G01 is interested.

Further, such a score may be used not only for the delivery of advertisements but also for, for example, sending direct mails and selecting business destinations. For example, when the score of a certain field becomes higher than a predetermined threshold value, the information distribution device 10 may present it to various business sources such as a trading company so as to carry out business related to the field.

[2. Information distribution device configuration]
Next, the configuration of the information distribution device 10 according to the embodiment will be described with reference to FIG. FIG. 2 is a diagram showing an example of a functional configuration of the information distribution device according to the embodiment. As shown in FIG. 2, the information distribution device 10 includes a communication unit 20, a storage unit 30, and a control unit 40. The communication unit 20 is realized by, for example, a NIC (Network Interface Card) or the like. Then, the communication unit 20 is connected to a network N such as the Internet by wire or wirelessly, and transmits / receives information to / from the terminal devices 100 and 101.

[2-1. Database stored by the storage unit]
The storage unit 30 is realized by, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory (Flash Memory), or a storage device such as a hard disk or an optical disk. In addition, the storage unit 30 stores the distribution information database 31, the action history database 32, the group database 33, and the user database 34.

Various information to be distributed is registered in the distribution information database 31. For example, in the distribution information database 31, advertisements classified by category, such as real estate information, travel information, cosmetics information, food information, music information, movie information, etc., are registered as information to be distributed.

The action history of any user is registered in the action history database 32. For example, FIG. 3 is a diagram showing an example of information registered in the behavior history database according to the embodiment. As shown in FIG. 3, the action history database 32 contains information having items such as "log ID", "IP address", "device information", "system information", "user ID", and "action content". Is registered. In addition, the "action content" includes items such as "browsing URL (Uniform Resource Locator)", "selection information", and "registration information".

Here, the "log ID" is an identifier for identifying each action history. The "IP address" is an IP address assigned to the hardware used by the user. Further, the "device information" is information indicating the type of hardware used by the user. Further, "system information" is information indicating the type of program used by the user. Further, the "user ID" is an identifier for identifying a user who has performed an action indicated by each action history.

Further, the "action content" is information indicating the content of the action performed by the user indicated by the associated "user ID". For example, the "browsing URL" is a URL for accessing the content such as a web page browsed by the user. Further, the "selection information" is information indicating various contents such as a still image, a moving image, music, an advertisement, etc. selected by the user on the web page indicated by the associated "browsing URL". Further, the "registration information" is the content of the information input or registered by the user on the web page indicated by the associated "browsing URL".

For example, the action history indicated by the log ID "ID1" is the hardware indicated by the device information "device # 1" by the user indicated by the user ID "user # 1", and is a program indicated by the system information "system # 1". Indicates that the hardware on which the system operates is used, and the IP address "address # 1" is assigned to the hardware. Further, in the action history indicated by the log ID "ID1", the registration information "information # 1" is displayed in the browsing URL "URL # 1" by the user indicated by the user ID "user # 1" using the above-mentioned hardware. Indicates that it has been registered.

In addition to the information shown in FIG. 3, arbitrary information that can be acquired via the Internet may be registered in the action history database 32. Further, in the example shown in FIG. 3, as the information registered in the action history database 32, "ID1", "address # 1", "device # 1", "system # 1", "user # 1", and "URL". Although conceptual values such as "# 1" and "information # 1" have been described, in reality, for example, character strings such as various numerical values and model numbers are registered.

Information indicating users belonging to the same group is registered in the group database 33. For example, FIG. 4 is a diagram showing an example of information registered in the group database according to the embodiment. In the example shown in FIG. 4, information having items such as "group ID", "name identification information", "user ID", and "common interest score" is registered in the group database 33. Further, the "name identification information" includes items such as "IP address" and "FP". In addition, the "common interest score" includes items such as "real estate", "travel", and "cosmetics".

Here, the "group ID" is an identifier that identifies a group that is a common social group. Further, the "name identification information" is information used when determining whether or not the user belongs to the group indicated by the associated "group ID". Further, the "user ID" is an identifier that identifies a user belonging to the group indicated by the associated "group ID". Further, the "common interest score" is a score indicating the degree of interest that the group indicated by the associated "group ID" has in each field of the information to be distributed.

For example, in the example shown in FIG. 4, in the group database 33, the hardware whose IP address is "address # 1" is used for the group indicated by the group ID "group # 1", and the fingerprint of the hardware is used. Information indicating that the user whose print value is "FP # 1" belongs is registered. Further, this information indicates that the user indicated by the user IDs "user # 1" and "user # 2" belongs to the group indicated by the group ID "group # 1". In addition, this information has a score of "score # 1" for information in the real estate field and a score of "score # 2" for information in the travel field for the group indicated by the group ID "group # 1", and the cosmetics field. Indicates that the score for the information in is "Score # 3".

In addition to the common interest score shown in FIG. 4, a common interest score for any field may be registered in the group database 33. Further, a user ID that identifies the same user may be registered in the group database 33 in association with a plurality of group IDs. Further, in the example shown in FIG. 4, conceptual values such as "group # 1", "address # 1", "FP # 1", and "score # 1" are described as the information registered in the group database 33. However, in reality, for example, various numerical values and character strings are registered.

In the user database 34, the information of the user to whom the information is distributed is registered. For example, FIG. 5 is a diagram showing an example of information registered in the user database according to the embodiment. For example, information including items such as "user ID" and "interest score" is registered in the user database 34. Here, the "interest score" includes items such as "real estate", "travel", and "cosmetics".

Here, the "interest score" is a score indicating the degree of interest that the user has in each field indicated by the associated "user ID". For example, in the example shown in FIG. 5, the score for the information in the real estate field of the user indicated by the user ID "user # 1" is "score # 11", and the score for the information in the travel field is "score # 12". Information that the score for the information in the cosmetics field is "score # 13" is registered. In the example shown in FIG. 5, a conceptual value such as "score # 11" is described as the information registered in the user database 34, but in reality, for example, various numerical values and character strings are registered. Become.

[2-2. An example of the configuration of the control unit]
Returning to FIG. 2, the description will be continued. The control unit 40 is stored in a storage device inside the information distribution device 10 by, for example, a CPU (Central Processing Unit), an MPU (Micro Processing Unit), an ASIC (Application Specific Integrated Circuit), an FPGA (Field Programmable Gate Array), or the like. It is realized by executing various programs in the RAM as a work area.

As shown in FIG. 2, the control unit 40 has a collection unit 41, a specific unit 42, a selection unit 43, and a distribution unit 44, and realizes or executes a function or operation of information distribution processing described below. The internal configuration of the control unit 40 is not limited to the configuration shown in FIG. 2, and may be any other configuration as long as it performs information distribution processing described later. Further, the connection relationship of each processing unit included in the control unit 40 is not limited to the connection relationship shown in FIG. 2, and may be another connection relationship.

The collection unit 41 collects the action history of each user. For example, the collection unit 41 collects logs from various log servers and the like (not shown), and uses the collected logs to access source IP address, device information, system information, and user ID of the accessing user. , And an action history associated with the action content is generated. Then, the collecting unit 41 registers the generated action history in the action history database 32. It should be noted that, as for the process of collecting the action history by the collecting unit 41, a known technique is used, and the description of the specific content of the process will be omitted.

The identification unit 42 identifies users who belong to a common social group, such as a common organization or a group having a predetermined human relationship. For example, the identification unit 42 identifies users belonging to a common social group based on the commonality of information related to the hardware used by the user U01. Specifically, the specific unit 42 has at least the commonality of IP addresses assigned to the hardware used by the user, device information indicating the type of hardware, and system information indicating the type of program executed by the hardware. Identify users who belong to a common social group based on any one commonality.

For example, the specific unit 42 identifies each action history registered in the action history database 32 with an IP address, device information, and system information. More specifically, the specific unit 42 calculates the fingerprint value from the device information and the system information, and sets a group for each combination of the IP address and the fingerprint value. Subsequently, the identification unit 42 calculates a set of the IP address and the fingerprint value for each user, and determines that each user belongs to a group in which the calculated IP address and the fingerprint value match. Then, the specific unit 42 registers the group ID of each group, the set of the IP address and the fingerprint, and the user ID of the user belonging to the group in the group database 33.

In addition, the specific unit 42 determines whether the user belongs to each group based on the history of the content browsed by the user, that is, the commonality of the "browsing URL" included in the action history, the commonality of the "registration information", and the like. It may be determined whether or not. For example, the specific unit 42 refers to the “browsing URL” browsed by each user from the behavior history of the users determined to be included in the same group based on the combination of the IP address and the fingerprint value. Then, the specific unit 42 may determine the similarity of the referenced "browsing URL" and exclude users having low similarity to the "browsing URL" of other users from the group. In addition, the specific unit 42 may group users based on the similarity of the “browsing URL”. In addition, the identification unit 42 may specify the social group to which the user belongs based on the content of the information registered by the user, and group the users based on the identity of the specified social group. ..

In addition, the identification unit 42 may specify the group to which each user belongs by using the scoring technique. For example, the specific unit 42 extracts all the pairs of the IP address and the fingerprint value included in the action history for each user, and the set of the extracted IP address and the fingerprint value and the name identification information of each group. Calculate the score indicating the degree of similarity and agreement with. Then, the specific unit 42 may determine that the user belongs to a group in which the calculated score value is higher than a predetermined threshold value.

Further, when calculating the score, the specific unit 42 may modify the score based on the similarity of the browsing URL, the content of the selection information, the content of the registration information, and the like. When such a process is executed, one or a plurality of groups to which the user belongs can be appropriately identified even when the user is using a plurality of hardware.

Here, an example of the process executed by the specific unit 42 will be described with reference to FIG. FIG. 6 is a diagram showing an example of the specific processing according to the embodiment. In the example shown in FIG. 6, an example of the process of grouping the users U01 to U09 is described. Further, in the example shown in FIG. 6, an example of the IP address of the hardware used by each user U01 to U09 and the fingerprint value is described.

For example, users U01 to U04 are using hardware to which "IP address # 1" is assigned and whose fingerprint value is "FP # 1". In such a case, the users U01 to U04 are predicted to be users belonging to the same home, department, or the like, for example. Therefore, the specific unit 42 determines that the users U01 to U04 are users belonging to the group G01.

On the other hand, users U05 to U09 are using hardware to which the same "IP address # 2" is assigned. However, the hardware fingerprint value used by the users U05, U06, and U09 is "FP # 2", whereas the hardware fingerprint value used by the users U07, U08 is "FP # 3". Is. In such a case, the users U05 to U09 are users belonging to the same company, but the users U05, U06, U09 and the users U07, U08 are predicted to be users belonging to different departments.

Therefore, the specific unit 42 executes the following processing. First, the identification unit 42 determines that the users U05 to U09 to which the same IP address is assigned to the hardware to be used are users belonging to the group G02. Subsequently, the identification unit 42 determines that the users U05, U06, and U09 having the same IP address and fingerprint value set are users belonging to the group G03, and the users U07 and U08 are users belonging to the group G04. Is determined. In this way, the specific unit 42 may be divided into groups in consideration of the hierarchy of the groups.

Returning to FIG. 2, the explanation will be continued. The selection unit 43 selects information to be provided to other users who belong to a social group common to the user, based on the user's behavior history. Specifically, the selection unit 43 refers to other users belonging to the common social group based on at least one of the commonality and the non-commonality of the behavior history of the plurality of users belonging to the common social group. Select the information you want to provide.

Specifically, the selection unit 43 estimates the interests of the social group based on the commonality of a plurality of users belonging to the common social group, and belongs to the social group based on the estimated interests. Select the information you want to provide to other users. Further, the selection unit 43 estimates the interests of each user based on the non-commonality of the behavior history of each user, and selects the information to be provided to each user based on the estimated interests.

Further, the selection unit 43 is an action history that has commonality among the action histories of a plurality of users belonging to the social group, and has no commonality with the action history of other users belonging to the social group. Select information to provide to other users based on history. For example, the selection unit 43 extracts a common action history from the action histories of the users U01 to U04. Then, the selection unit 43 identifies an action history that is not common to the action history of the user U01 from the extracted action history, and selects information to be distributed to the user U01 based on the specified action history. By executing such a process, the selection unit 43 can target the information that the user U01 is personally interested in.

For example, FIG. 7 is a diagram showing an example of the selection process according to the embodiment. In the example shown in FIG. 7, an example of processing when the user U02 and the user U03 belong to the group G01 is described. For example, in the example shown in FIG. 7A, a part of the action history L02 of the user U02 and the action history L03 of the user U03 overlap. It is considered that such an overlapping portion of the action history indicates information that the user U02 and the user U03 are commonly interested in, that is, information that the user U02 is interested in as a group G01. Therefore, the selection unit 43 uses the overlapping portion of the action history L02 of the user U02 and the action history L03 of the user U03 to select the information C03 that the user U02 is interested in as the group G01.

Further, as shown in FIG. 7B, it is considered that the range of the action history L02 of the user U02 that does not overlap with the action history L03 of the user U03 indicates information that the user U02 is personally interested in. Be done. Therefore, the selection unit 43 selects the information C04 that the user U02 is personally interested in by using the portion of the action history L02 of the user U02 that does not overlap with the action history L03 of the user U03.

Further, as shown in FIG. 7C, when the action history L02 of the user U02 and the action history L03 of the user U03 do not overlap, the users U02 and U03 belong to a common social group. Despite this, it is predicted that the fields of information that are of mutual interest are unknown. Therefore, the selection unit 43 uses the action history L02 to select the information C05 that the user U02 is interested in, and uses the selected information C05 as information to notify the user U03. That is, the selection unit 43 notifies the other user in the same group of information that is presumed to be of interest to one user. In addition, the selection unit 43 calculates the degree of interest that each user has in each field based on the behavior history of each user, that is, the interest score first, and each is based on the calculated value of the interest score. Areas in which users are commonly interested or areas in which each user is personally interested may be specified.

Hereinafter, an example of the process executed by the selection unit 43 will be described. First, the selection unit 43 extracts the behavior history of each user, and calculates the degree of interest that each user has in each field of information, that is, the interest score, based on the extracted behavior history. Then, the selection unit 43 registers the calculated score in the user database 34.

Further, the selection unit 43 selects one group registered in the group database 33 and identifies a user belonging to the selected group. In addition, the selection unit 43 extracts the interest score associated with the user ID of the specified user. Then, the selection unit 43 calculates the value of the common interest score of the selected group based on the extracted value of the interest score, and registers the calculated value in the group database 33. For example, the selection unit 43 may calculate the sum of the values of the interest scores of each user for each type of information, and use the calculated sum values as the common interest scores.

Subsequently, the selection unit 43 identifies the group to which the user to whom the information is to be distributed belongs. For example, the selection unit 43 specifies the group indicated by the group ID "group # 1" as the group to which the user indicated by the user ID "user # 1" belongs. Then, for example, when the selection unit 43 targets the information that the specified group is interested in, the value of the common interest score in the field of information associated with the group ID "group # 1" is set. Identify areas above a predetermined threshold. Then, the selection unit 43 acquires the information of the specified field from the distribution information database 31.

On the other hand, for example, when the user to whom the information is to be distributed distributes the information that the user is personally interested in, the selection unit 43 extracts the value of the interest score associated with the user ID of the user from the user database 34. .. In addition, the selection unit 43 extracts the value of each common interest score of the group to which the user to whom the information is to be distributed belongs. Then, the selection unit 43 identifies a field of information in which the value of the interest score is higher than the predetermined threshold value and the value of the common interest score is lower than the predetermined threshold value, and the information of the specified field is distributed to the distribution information database 31. Get from.

The selection unit 43 may select information to be distributed based on the order of each user. For example, the selection unit 43 determines which user has the right to convert, which user is the leader of the group, and which user is the husband or wife, based on the registration information of each user belonging to the common group. , Identify the order and roles such as which user is the parent and which user is the child.

Then, the selection unit 43 selects the information to be distributed based on the order of the users to whom the information is distributed. For example, when the selection unit 43 identifies that the user to whom the information is delivered is the husband, the selection unit 43 selects based on the interest score of the user who belongs to the same group as the user and is identified as the wife. The information provided may be selected as the distribution target. Further, when the selection unit 43 identifies that the user to whom the information is distributed is the leader of the group, the value of the interest score of the user is higher than a predetermined threshold value, and the common interest score of the group is set. Information in a field whose value is lower than a predetermined threshold value may be selected as information to be distributed to other users belonging to the group.

The selection unit 43 estimates the interests of the first social group based on the commonality of the behavior history of each user belonging to the first social group, and the second selection unit 43 estimates the interests of the estimated interests. You may choose to provide information to users who belong to the social group of. For example, the selection unit 43 identifies a field in which the value of the common interest score associated with the group ID “group # 1” is higher than a predetermined threshold value, and the information of the specified field is referred to as the group ID “group # 2”. It may be selected as information to be delivered to users belonging to the group indicated by.

Further, when the user selects the information delivered to the user, the selection unit 43 provides information of the same type of the delivered information but different contents to another user. May be selected as. For example, when the selection unit 43 delivers information about an advertisement to a user and the user selects the information, the selection unit 43 purchases an advertisement target from another user belonging to a social group common to the user. You may select the suggested information.

For example, FIG. 8 is a diagram showing an example of information selected by the selection unit according to the embodiment. For example, in the selection unit 43, text such as "play a movie!" Is arranged as information to be distributed to children of a certain family, and when the text is selected, a promotional video of the game is played. Select information C06. Then, for example, when the information C06 is selected by the user (that is, a child of a certain family) and the promotional movie is played, the selection unit 43 provides the information C06 as information to be distributed to the parents of the family. Among them, select the information C07 in which the text such as "Play movie!" Is changed to the text such as "Buy now!" With a link to the purchase page of the game. That is, when a user browses a moving image related to an advertisement, the selection unit 43 purchases an advertisement target of the advertisement related to the viewed moving image to another user belonging to a social group common to the user. Select the information you propose to be delivered.

Returning to FIG. 2, the explanation will be continued. The distribution unit 44 distributes the information selected by the selection unit 43. For example, the distribution unit 44 identifies a user to whom the information is distributed, and notifies the selection unit 43 of the specified user. Then, the distribution unit 44 distributes the information selected by the selection unit 43 as the information to be distributed to the notified user to the specified user.
