  Exemplary embodiments of an attribute estimation program and an attribute information providing system according to the present invention will be described below in detail with reference to the accompanying drawings.

  In the following first embodiment, the outline and features of the attribute estimation device that executes the attribute estimation program according to the present invention, the configuration of the attribute estimation device, and the effects of the first embodiment will be described in order.

[Outline and features of attribute estimation device]
First, the outline and features of the attribute estimation apparatus according to the first embodiment will be described with reference to FIG. FIG. 1 is a system configuration diagram illustrating an overall configuration of a system including an attribute estimation apparatus according to the first embodiment. As shown in the figure, in this system, a terminal device 10 and a search server device 20 are connected to be communicable with each other via the Internet, and the search server device 20 and the attribute estimation device 30 are connected via a network. It is configured to be communicable with each other.

  In such a system, the terminal device 10 receives an input or selection of a search word from a user and transmits the search word to the search server 20, and the search server 20 is based on the search word received from the terminal device 10. Performing a WEB search and transmitting a search result (a list of URLs of WEB sites corresponding to the search term) to the terminal device 10, and the attribute estimation device 30 estimating the attribute of the user of the terminal device 10. In particular, the attribute estimation device 30 is characterized mainly in that the attribute of the user of the terminal device 10 can be accurately estimated.

  The main feature will be specifically described. The attribute estimation device 30 stores a search term input or selected by the user from the terminal device 10 and a user ID for uniquely identifying the user in association with each other. A search word log database (search word log DB) 32a is provided. Specifically, when a search term is input from the terminal device 10 to the search server 20 by the user, the search term is associated with the user ID and stored as “01, new graduate recruitment / nurse”.

  Further, the attribute estimation device 30 includes an attribute database (attribute DB) 32b that stores a predetermined attribute and a search term that is highly likely to be input or selected by a user having the attribute in association with each other. Specifically, predetermined attributes and search terms are stored in advance as “20s, new graduate recruitment / graduation ceremony / graduate school” or “female, nurse / divination”.

  In addition, the attribute estimation device 30 includes a user information database (user information DB) 32c that stores the estimated user attributes and user IDs in association with each other. Specifically, “01, 20s / female” is stored in association with the estimated user attribute and user ID.

  The terminal device 10 stores “01” as a user ID for uniquely identifying the user. Specifically, the user ID assigned by the attribute estimation device 30 to uniquely identify the user via the search server device 20 is temporarily written and stored using, for example, Cookie. is doing.

  In such a configuration, when a certain search word is input or selected in the terminal device 10 accessing the search server device 20 ((1) in FIG. 1), the search server device 20 is stored in the terminal device 10. The acquired user ID and the input search term are acquired ((2) in FIG. 1). To give a specific example, when the search term “new graduate recruitment, nurse” is input in the terminal device 10 with the user ID “01”, the search server device 20 is stored in the terminal device 10. The search term “new graduate recruitment, nurse” input with the ID “01” is acquired.

  Subsequently, the search server device 20 transmits the acquired user ID and search word to the attribute estimation device 20 ((3) in FIG. 1), and the attribute estimation device 30 receives the received user ID and search word. Are stored in the search term log DB 32a in association with each other ((4) in FIG. 1). Specifically, in the above example, the search server device 20 transmits the acquired user ID “01” and the search term “new graduate recruitment, nurse” to the attribute estimation device 20, and the attribute estimation device 30. Stores the received user ID “01” and the search term “new graduate recruitment, nurse” in the search term log DB 32a in association with each other.

  And the attribute estimation apparatus 30 estimates a user's attribute based on a match with the search word memorize | stored in search word log DB32a, and the search word memorize | stored in attribute DB32b ((5) of FIG. 1). For example, the attribute estimation unit 33a stores “new graduate recruitment, nurse” entered as a search word by the user with the user ID “01” in the user DB 32a, and “attributes, search” in the attribute DB 32b. When “20s, new graduate recruitment / graduation ceremony / graduate school” and “female, nurse / fortune telling” are stored as “word”, the search term of the attribute “20s” is “new graduate recruitment” entered by the user Since “Nurse” matches the search term of the attribute “female”, the attribute of the user ID “01” that has entered “new hiring, nurse” as the search term is set to “20s, female ".

  Thereafter, the attribute estimation device 30 stores the estimated user attribute and the user ID in association with each other in the user information DB 32c ((6) in FIG. 1). Specifically, in the above example, (01, 20s / female) is stored in the user information DB 32c in association with the estimated user attribute and user ID.

  As described above, according to the first embodiment, as in the main feature described above, a search word that is less likely to contain noise as a result of reflecting the user's intention, for example, a word that represents the same thing but has different expressions between men and women. As a result of being able to estimate attributes (age group, gender, residential area, etc.) from words used by a specific age group (for example, nurses and nurses) (for example, recruiting new graduates) It is possible to estimate well with the system.

[Configuration of Attribute Estimation Device (Example 1)]
Next, the configuration of the attribute estimation apparatus 30 shown in FIG. 1 will be described with reference to FIGS. 2 is a block diagram illustrating a configuration of the attribute estimation device 30, FIG. 3 is a diagram illustrating an example of a search term log DB, and FIG. 4 is a diagram illustrating an example of an attribute DB. FIG. 5 is a diagram illustrating an example of the user information DB. As shown in FIG. 2, the attribute estimation device 30 includes a communication control I / F unit 31, a storage unit 32, and a control unit 33.

  Among these, the communication control IF unit 14 is a means for controlling communication related to various information exchanged with the search server device 32. Specifically, the search term input from the terminal device 10 and the terminal device 10 The user ID assigned to the user is received from the search server device 20.

  The storage unit 32 is a storage unit (storage unit) that stores data and programs necessary for various processes performed by the control unit 33. In particular, the storage unit 32 is closely related to the present invention. A DB 32b and a user information DB 32c are provided. The search term log DB 32a corresponds to the “search term storage means” described in the claims. Similarly, the attribute DB 32b corresponds to the “attribute storage means”, and the user information DB 32c includes “user attribute”. Corresponds to "memory means".

  Among these, the search term log DB 32a is a means for storing a search term input or selected by the user from the terminal device 10 in association with a user ID for uniquely identifying the user. As illustrated in FIG. 3, the user ID and the search word are associated with each other and “01, new graduate recruitment / nurse” and the like are stored.

  The attribute DB 32b is a means for storing a predetermined attribute and a search term that is highly likely to be input or selected by a user having the attribute from the terminal device, specifically, as illustrated in FIG. As described above, a predetermined attribute and a search word are associated with each other, and “20s, new graduate recruitment / graduation ceremony / graduate school”, “female, nurse / divination”, and the like are stored.

  Further, the user information DB 32c is a means for storing a user attribute and a user ID estimated by the attribute estimation unit 33a described later in association with each other. Specifically, as illustrated in FIG. The person ID and the estimated attribute are associated with each other and stored as “01, female / 20s”.

  The control unit 33 has an internal memory for storing a control program such as an OS (Operating System), a program defining various processing procedures, and required data, and executes various processes using these. In particular, as closely related to the present invention, an attribute estimation unit 33a is provided. The attribute estimation unit 33a corresponds to “attribute estimation means” recited in the claims.

  The attribute estimation unit 33a is a means for estimating a user attribute based on a match between a search word stored in the search word log DB 32a and a search word stored in the attribute DB 32b. Specifically, “new graduate recruitment, nurse” entered as a search word by the user with the user ID “01” is stored in the user DB 32a (see FIG. 3), and “attribute, search word” is stored in the attribute DB 32b. When “20s, new graduate recruitment / graduation ceremony / graduate school” and “female, nurse, fortune telling” are stored (see FIG. 4), the search term “attributed to“ 20s ”is“ new graduate recruitment ”entered by the user. And “Nurse” matches the search term of the attribute “female”, the attribute estimation unit 33a has the user ID “01” that has entered “New graduate recruitment, nurse” as the search term. The user attribute is estimated as “20s, female”.

  The attribute estimation unit 33a stores the user attribute and the user ID estimated as described above in the user information DB 32c in association with each other. Note that the attribute estimation processing by the attribute estimation unit 33a is attribute estimation from the administrator via the timing at which the attribute estimation request is received from the search server device 20 or the operation unit (not shown in FIG. 2) of the attribute estimation device 30. It is executed at an arbitrary timing such as a timing when a request is input or every predetermined time interval.

[Processing by attribute estimation device]
Next, attribute estimation processing by the attribute estimation apparatus will be described with reference to FIG. FIG. 6 is a flowchart showing the flow of attribute estimation processing.

  As illustrated in FIG. 6, when the attribute estimation device 30 receives an attribute estimation request from the search server device 20 (Yes in step S601), the attribute estimation device 30 obtains a user ID and a search word corresponding to the user ID from the search word log DB 32a. In addition to reading, the combination of the search word and the attribute is read from the attribute DB 32b (step S602).

  Subsequently, the attribute estimation device 30 estimates the attribute of the user based on the match between the search word read from the search word log DB 32a and the search word read from the attribute DB 32b (step S603). For example, “new graduate recruitment and nurse” entered by the user with the user ID “01” as a search word is stored in the user DB 32a (see FIG. 3), and “attributes and search words” are stored in the attribute DB 32b as “20s. , “New graduate recruitment / graduation ceremony / graduate school” and “Women, nurses / fortune telling” are stored (see FIG. 4), the “new graduate recruitment” entered by the user matches the search term of the attribute “20s”. In addition, since “nurse” matches the search term of the attribute “female”, the attribute estimation unit 33a determines the attribute of the user with the user ID “01” who entered “new graduate recruitment, nurse” as the search term. Are estimated to be “female in their 20s”.

  Then, the attribute estimation apparatus 30 stores the estimated user attribute (for example, twenties, female) and the user ID (for example, 01) in association with each other in the user information DB 32c (step S604).

[Effect of Example 1]
As described above, according to the first embodiment, the search term input or selected by the user from the terminal device 10 is stored in association with the user ID for uniquely identifying the user, A search term that is likely to be input or selected from the terminal device 10 by a user having the attribute is stored in association with the search term stored in the search term log DB 32a and the search term stored in the attribute DB 32b. Since the attribute of the user is estimated based on the match and the estimated attribute of the user and the user ID are stored in association with each other, a search term that is less likely to contain noise as a result of reflecting the user's intention, For example, attributes (age group, gender, residential area) such as words that represent the same thing but have different expressions between men and women (for example, nurses and nurses) and words used by a specific age group (for example, new graduate recruitment) Etc.) It may result, it is possible to estimate better system attributes of the user of the terminal device.

  By the way, in the first embodiment, a case has been described in which a user's attribute is estimated using a search word stored in advance in the attribute DB 32b. However, the present invention is not limited to this and is stored in the search word log DB 32a. The search term used for attribute estimation may be used recursively in subsequent attribute estimation. In the first embodiment, a case where a single attribute is stored in the attribute DB 32b has been described. However, the present invention is not limited to this, and conflicting attributes are stored in the attribute DB 32b. Also good.

  Therefore, in the second embodiment, the search terms used for attribute estimation are used recursively in the subsequent attribute estimation using FIGS. 7 to 10, and the search terms are associated with each conflicting attribute. Will be described. In the following, the configuration of the attribute estimation apparatus, the flow of attribute estimation processing, and the effects of the second embodiment will be described in order. 7 is a flowchart illustrating the flow of attribute estimation processing according to the second embodiment, FIG. 8 is a diagram illustrating an example of a search term log DB according to the second embodiment, and FIG. 9 is related to the second embodiment. FIG. 10 is a diagram illustrating an example of a user information DB according to the second embodiment.

[Configuration of Attribute Estimation Device (Example 2)]
First, the configuration of the attribute estimation apparatus 30 according to the second embodiment will be described. Since the configuration is basically the same as that of the first embodiment, an attribute DB 32b and an attribute estimation unit that are different from the first embodiment are described below. Only 33a will be described. In the second embodiment, as shown in FIG. 8, the search term log DB 32a stores a plurality of search terms in association with each of a plurality of users. Also, as shown in FIG. In the information DB 323c, a plurality of attributes are associated with each other and stored.

  The attribute DB 32b associates and stores a search term for each conflicting attribute. Specifically, as shown in FIG. 9, search terms are stored for each conflicting attribute such as “male” and “female”, “20s” and “30s”.

  Further, the attribute DB 32b newly stores a search word and an attribute used for estimation by attribute estimation in association with each other. As a specific example, a predetermined user group is estimated as “male” by the attribute estimation process, and the majority of users included in the predetermined user group used the search term “PC”. In such a case, the attribute “male” and the search term “sea” are newly stored in the attribute DB 32b. The search word stored in the search word log DB 32a and used for attribute estimation is used recursively in subsequent attribute estimation.

  The attribute estimation unit 33a is a means for estimating user attributes. Specifically, the attribute of the user and the attribute of the search term are newly supplemented to the attribute DB 32b, and the attribute of the user is estimated recursively. Details of the processing by the attribute estimation unit 33a will be described later with reference to FIG.

[Processing by Attribute Estimation Device (Example 2)]
Next, attribute estimation processing by the attribute estimation device 30 will be described with reference to FIG. As shown in FIG. 7, when the attribute estimation device 30 receives an attribute estimation request from the outside (Yes in step S701), the attribute estimation device 30 can search the attribute DB 32b with a search word group A1 that can be estimated with high accuracy. The search term group B1 that can be estimated with high accuracy that the attribute is not α is read out and set in the work area (step S702). Specifically, from the attribute DB 32b shown in FIG. 9, it is estimated with high accuracy that the search term group A1 can be estimated with high accuracy that the attribute is “male” and the attribute is “female”. Each possible search term group B1 is read out and set in the work area.

  Subsequently, the attribute estimation device 30 sets i = 1 (step S703), and searches from the search word log DB 32a for a user group Ci searching for Ai and a user searching for Bi that conflicts with the attributes of Ai. Each group Dj is extracted (step S704). As a specific example, from the search word log DB 32a shown in FIG. 8, a user group searching for “police officer” is extracted as Ci, and also searching for “female police officer”. The user group is extracted as Dj. In this example, the user group Ci is estimated as the attribute “male”, and the user group Di is estimated as the attribute “female”.

  Then, the attribute estimation device 30 searches the search term log DB 32a for a search term group in which K% or more of the user group Ci performs a common search and L% or more of the user group Dj does not perform a search. Extract as group Ai + 1 (step S705). To give a specific example, K% or more (for example, 80% or more) of the user group Ci searching for “police officer” performs a common search, and also searches for “police officer”. The search term “sea” is used as a search term group Ai + 1 as a search term in which L% or more (for example, 80% or more) of the user group Dj who has not performed a search (ie, “female police officer”) has not performed a search. (See FIG. 8). In this example, the attribute “male” and the search term “sea” are newly stored in the attribute DB 32b.

  Subsequently, the attribute estimation device 30 searches the search term log 32a for a search term group in which K% or more of the user group Dj performs a search in common and L% or more of the user group Ci does not perform a search. Extracted as the word group Bi + 1 (step S706). To give a specific example, K% or more (for example, 80% or more) of users Dj who are searching for “female police officers” commonly search, and “female police officers” are also searching. The search term “fortune” is set as the search term group Bi + 1 as a search term in which L% or more (for example, 80% or more) of the user group Dj not (that is, searching for “police officer”) is not searching. Extract (see FIG. 8). In this example, the attribute “female” and the search term “fortune telling” are newly stored in the attribute DB 32b.

  Then, the attribute estimation apparatus 30 determines whether i is equal to or greater than j (step S707). If i is not equal to or greater than j (No in step S707), the process returns to step S704, and the user groups Ci and Dj are extracted again. Then, the processes in steps S705 to S707 are repeated. That is, in the above-described example, the user group Ci and the user group Di are newly extracted based on the search terms “sea” and “fortune telling” extracted in the process of step S704, A new search term is extracted from the search term log 32a by the processing of S705 and S706.

  On the other hand, if i is greater than or equal to j (Yes at Step S707), the attribute estimation device 30 sets the attribute of the estimated user group Ci to “α” for each process of Step S704 that is repeatedly executed, The estimation result that the attribute of the user group Di is “not α” is stored in the user information DB 32c (step S708). Specifically, as shown in FIG. 10, “02, male / 20's” “10, female” is stored.

[Effect of Example 2]
As described above, according to the second embodiment, the attribute DB 32a newly stores the search word and the attribute used for estimation in association with each other, and the attribute estimation unit 33a newly searches the search word log DB 32a. User attributes are estimated using words and attributes. By adding the search terms and attributes used for user attribute estimation, the coverage of the predetermined attributes is improved. It is possible to further improve the accuracy of the results.

  Further, according to the second embodiment, the attribute DB 32a stores a search term in association with each conflicting attribute, and the attribute estimation unit 33a is stored in the search term and attribute DB 32a stored in the search term log DB 32a. Since the user attribute is estimated based on the match with the search term for each conflicting attribute, the result of the estimation using conflicting attributes of the search term (for example, male, female, etc.) It is possible to obtain an estimation result with higher accuracy than in the case of estimation using only attributes.

  In the first and second embodiments described above, the case where only the attribute is acquired as the estimation result has been described. However, the present invention is not limited to this, and the estimation accuracy indicating the accuracy of the estimated attribute is calculated. You may do it. Therefore, in the following, as the third embodiment, a case where the estimation accuracy is calculated will be described. Note that this estimation accuracy calculation processing is executed following the processing in steps S705 and S706, for example, in the flowchart shown in FIG.

  For example, as illustrated in FIG. 11, the attribute estimation device 30 sets “an” as a probability that a user whose attribute is A inputs a search word n, and sets a probability that a user whose attribute is not A as input a search word n. bn ", the probability that a user whose attribute is A inputs the search word m is" am ", and the probability that a user who does not have the attribute A inputs the search word m is" bm ", and then the attribute is A A probability “anm” in which the user inputs both the search word n and the search word m, and a probability “bnm” in which a user whose attribute is not A input the search word n and the search word m are calculated, respectively, and the search word n The probability that the attribute of the user who has input both the search term m is A is calculated as “anm / (anm + bnm)”. That is, when the user whose attribute “A” is estimated inputs both the search word n and the search word m, the accuracy of the estimated attribute “A” is calculated as described above. Become.

  Then, the attribute estimation device 30 stores the estimation accuracy calculated as described above in association with the user ID in the user information DB 32c together with the attribute. Specifically, as shown in FIG. 12, in association with the user ID, the estimated gender, gender estimation accuracy, estimated age group, age group estimation accuracy, estimated residence area, The estimated accuracy of the residential area is stored in the user information DB 32c (see (1) in the figure). In addition, although the example which estimated sex, an age group, and a residence area was shown here as an attribute, these are only examples, and as shown in the same figure, other attributes (occupation, preference, etc.) are estimated. In addition, the user information may be stored in an expansion table.

  Thus, according to the third embodiment, as a result of calculating the estimation accuracy in association with the attribute and user ID, the accuracy of the estimation result of each user ID or attribute can be known, and the accuracy of the estimation result can be determined. It can be a guideline for further improvement.

  Incidentally, in the above-described embodiment, the attribute DB and search word storage processing for the attribute DB 32a is not specified, but the search word input or selected by the user from the terminal device 10 whose attribute is known in advance is stored in the attribute DB 32b. You may make it store.

  Therefore, as a fourth embodiment, a case where a user attribute (user attribute) is estimated using a search term from the terminal device 10 whose attribute is known in advance will be described with reference to FIG. FIG. 13 is an overall configuration diagram of a system including an attribute estimation device using a mobile phone network.

  As shown in FIG. 13, the terminal device 130 and the search server 131 are connected to be communicable with each other via the Internet, the search server 131 and the attribute estimation device 135 are connected, and the mobile phone 133 The search server 134 is connected to be communicable with each other via a mobile phone network, and the search server 134 and the attribute estimation device 135 are connected. Note that the mobile phone 133 is, for example, a personal computer, a workstation, a home game machine, an Internet TV, a PDA, or a mobile communication terminal such as a mobile phone or a PHS.

  Here, since the mobile phone 133 requires personal information to make a contract, the attributes of the user (user) are known in advance. When the user accesses the search server 134 from the mobile phone 133 and inputs a search term, the search server 134 assigns a user ID uniquely to the user of the mobile phone 133 and associates the user ID with the search term. Store in the log DB.

  Then, the attribute estimation device 135 stores the search term input or selected by the user from the mobile phone 133 whose attribute is known in advance in association with the predetermined attribute in the attribute DB, and is stored in the search term log DB. The attribute of the user (user) is estimated based on a match between the search term and the search term input or selected by the user whose attribute is stored in advance in the attribute DB. The search term log DB corresponds to “search term storage means” described in the claims, and similarly, the attribute DB corresponds to “attribute storage means”.

  For example, when the user of the mobile phone 133 who is “20 years old, male” inputs the search term “employment”, the attribute estimation device 135 uses “employment” as the search terms for “20 years old” and “male” in the attribute DB. ”And the attribute of the user (user) is estimated based on the match between the search word stored in the search word log DB and the search word input by the user (user). Then, as an estimation result, the attributes of the user (user) such as “20 years old, male, student” are estimated in more detail.

  As described above, according to the fourth embodiment, the attribute DB 32b stores the search term input or selected by the user from the mobile phone 133 whose attribute is known in advance in association with the predetermined attribute, and the attribute estimation device. 135 is based on a match between a search word stored in the search word log DB and a search word input or selected by a user (user) whose attribute stored in the attribute DB is known in advance. Since the attribute is estimated, for example, when a search word from a terminal device whose attribute is known is used as a result of estimating the attribute using a search word from a terminal device such as a mobile phone, the attribute is estimated in advance. It is possible to obtain an estimation result with higher accuracy than.

  By the way, in the above-described embodiment, the case where the user attribute (user attribute) is estimated using only the search term from the terminal device 10, the present invention is not necessarily limited to this, and the terminal device 10 is not limited thereto. The user attribute (user attribute) may be estimated by further using the URL information and the search term browsed from or entered and / or the IP address of the terminal device 10.

  Specifically, as shown in FIG. 14, the search term log DB 32a stores the date and time when the user (user) executed the search or the date and time when the URL was selected from the search result, and the access source IP address of the user (user). , A unique identifier of the user (user), a search term input by the user (user), and URL information when the user (user) selects a URL from the search result, “Data, IP, User_ID, Keyword, URL "is stored. For example, “2006/1/1, 192.168.1.1, 0001, entrance examination, http://www.xxx.yyy.com” is stored. Then, the attribute estimation apparatus 30 according to the fifth embodiment estimates the user's attribute using not only the search word but also the above-described URL information, search time, and the IP address of the terminal device 10.

  As described above, according to the fifth embodiment, the attribute estimation unit further estimates the user's attribute by using the URL information browsed from the terminal device by the user. As a result of using the search term, it is possible to obtain an estimation result with higher accuracy than in the case of estimation using only the search term.

  Further, according to the fifth embodiment, the attribute estimation unit estimates the user's attribute by further using the time when the search word is input or selected by the user from the terminal device and / or the IP address of the terminal device. As a result of further estimation using the time when the search word is input or selected and / or the IP address of the terminal device, it is possible to obtain an estimation result with higher accuracy than in the case of estimation using only the search word. .

  By the way, the present invention may provide the estimated attribute information to another device or system. Therefore, in the sixth embodiment, a system using attribute information estimated by the attribute estimation device will be described with reference to FIGS. 15 and 16. FIG. 15 is a diagram illustrating an overall configuration of a service example (information provision) using attribute information according to the sixth embodiment. FIG. 16 is a diagram illustrating a service example (advertisement provision) using attribute information according to the sixth embodiment. It is a figure which shows the whole structure.

[Service example of attribute estimation processing (information provision)]
As shown in FIG. 15, a terminal device 150 for inputting a search word by a user (user), a WWW server 151 for providing a WEB page according to the input search word, and a user (user) of the terminal device 150 ) Is provided so as to be able to communicate with each other via the Internet.

  The information providing server 152 includes a user information DB that stores user attributes and user IDs in association with each other. Further, the terminal device 150 holds the uniquely assigned user ID in the cookie file.

  Under such a configuration, when the user accesses the WWW server 151 from the terminal device 150 and transmits a browsing request for the WEB page ((1) in FIG. 15), the WWW server 151 determines the WWW server ID and the final value. A transfer URL including the URL to be accessed and the transaction code is returned to the terminal device 150 ((2) in FIG. 15).

  Subsequently, the terminal device 150 adds the user ID in the cookie file to the received transfer URL and accesses the information providing server 152 ((3) in FIG. 15). Then, the information providing server 152 holds the received transfer URL and instructs the transfer to the URL to be finally accessed ((4) in FIG. 15).

  Thereafter, the terminal device 150 accesses the instructed URL ((5) in FIG. 15). Then, the accessed web server (not shown) notifies the information providing server of its WWW server ID and transaction code ((6) in FIG. 15).

  Thereafter, the information providing server 152 identifies the user ID from the received WWW server ID and transaction code, extracts the attribute from the user information DB, and transmits the extracted attribute to the web server ((7) in FIG. 15). . Then, the web server that has received the attribute displays a WEB page such as content suitable for the attribute on the terminal device 150 ((8) in FIG. 15).

[Service example of attribute estimation processing (advertisement provision)]
As shown in FIG. 16, a terminal device 160 that browses a WEB page by a user (user), a WWW server 161 that provides a WEB page according to an input search word, and a user (user) of the terminal device 160 ) Is provided so as to be able to communicate with each other via the Internet.

  The advertisement providing server 162 includes a user information DB that stores user attributes and user IDs in association with each other. In addition, the terminal device 160 holds a uniquely assigned user ID in the cookie file.

  As shown in FIG. 16, when the user accesses the WWW server 151 from the terminal device 160 and transmits a web page browsing request ((1) in FIG. 16), the WWW server 161 accesses the advertisement providing server 162. Is transmitted to the terminal device 160 ((2) in FIG. 16).

  Subsequently, the terminal device 160 that has received the response transmits the user ID of the cookie file to the advertisement providing server ((3) in FIG. 16). Then, the advertisement providing server 162 extracts an attribute corresponding to the received user ID from the user information DB, and transmits an advertisement suitable for the extracted attribute to the terminal device 160 ((4) in FIG. 16).

[Effects of Example 6]
As described above, according to the sixth embodiment, the information stored in the user information DB is provided to other terminal devices, so that, for example, attribute information can be shared among a plurality of other sites such as a search engine. It is not necessary to estimate the attribute at each site, and it is possible to suppress capital investment when performing a service that requires attribute information.

  Further, according to the sixth embodiment, the information providing server 152 associates and stores a search term input or selected by the user from the terminal device 150 and a user ID for uniquely identifying the user, A predetermined attribute and a search term that is likely to be input or selected by the user having the attribute from the terminal device 150 are stored in association with each other and stored in the search term storage unit and the attribute storage unit. User attribute is estimated based on the match with the search term, the estimated user attribute and the user ID are stored in association with each other, and a request relating to the user attribute is received from the WWW server 151 In this case, the estimated user attribute is transmitted to the WWW server 151, and the WWW server 151 transmits a request related to the user attribute of the terminal device 150 to the information providing server 152, and the user attribute is Since the predetermined information is transmitted to the terminal device 150 based on the received user attributes received from the service server 152, even when the WWW server 151 and the information providing server 152 belong to different domains (for example, search service When the attribute estimation service is performed by different companies), the user ID is not known to the WWW server 151, and the service using the attribute information estimated by the information providing server 152 can be performed.

  Further, according to the sixth embodiment, the advertisement providing server 162 stores a search term input or selected by the user from the terminal device 160 in association with a user ID for uniquely identifying the user, A search term stored in the search term storage unit and a search term stored in the attribute storage unit are stored in association with a predetermined attribute and a search term that is likely to be input or selected by a user having the attribute. The user attribute is estimated based on the match, the estimated user attribute and the user ID are stored in association with each other, and the terminal device 160 accessing the WWW server 161 changes the user attribute to the user attribute. When such a request is received, predetermined information corresponding to the estimated user attribute is transmitted to the terminal device 160, and the WWW server 161 accepts access from the terminal device 160 and sends the access response. Therefore, when the WWW server 161 and the advertisement providing server 162 belong to the same domain (for example, when the search service and the advertisement service are performed by the same company), the cost can be reduced when the system is constructed without constructing a complicated system configuration. And the attribute information estimated by the advertisement providing server 162 can be used.
