The user relationship information 1030 is information indicating a human relationship centered on the user, and here, information on the user having an intimate relationship is handled. A user who has an intimate relationship is an additional information registered user who has a high chance of judging that the additional information viewed by the user who has viewed the additional information is important. It is a user who added a lot. The user ID 1031 having an intimate relationship can be set by the user himself or automatically by the user management function 131 using data obtained from another system.

  The additional information association management function 132 manages association between additional information and related content. In this embodiment, since the additional information is distributed between the related contents, the additional information association management function 132 also manages the association between the additional information after distribution and the related contents. The additional information association management function 132 stores the additional information association management file 212 as additional information association management data in the storage device, and stores the additional information file 213 as additional information data in the storage device.

  FIG. 3 shows an example of the additional information association management file of the additional information server. The additional information association management file 212 is a content to which additional information is added, that is, an additional information target content URL 2000 that is an original content URL, a content type 2010, and an additional information disclosure condition 2020 that specifies conditions for publishing additional information. And an additional information registration user ID 2030 and an additional information ID 2040 that is identification information of the additional information. The content URL such as the additional information target content URL 2000 may be other identification information that can identify the original content.

The additional information file 213 includes an additional information ID 2040, additional information content 3010, additional information target content URL (original content URL) 2000, and additional information disclosure condition 2020. The additional information disclosure condition 2020 indicates the case of a large number of unspecified users, but when additional information is disclosed to a specific user, it is specified by a user ID or user attribute information.

The related content search function 133 searches for new related content as a new association destination for existing additional information. The following method is used as an example of the search method.
(1) Search for related content using the logical structure of the original content.
(2) Search for content that includes the keyword included in the URL of the original content and the same keyword or a keyword treated as a synonym in the URL.
(3) Analyzing sentences in the original content and searching for content having similar contents.

  When the additional information disclosure condition 2020 is specified by a user ID, the mail transmission function 134 indicates that the specified user ID is not registered in the user information file 211 shown in FIG. The presence / absence of additional information or the content thereof is notified using e-mail. The content of the notified e-mail includes, as an example, the content of additional information, the content URL corresponding to additional information, and the information of the additional information registered user.

  The content server 104 includes means for executing a content distribution function 140 that distributes content such as documents to user terminals via the Internet 105 in response to a request from the additional information server 103. The content distribution function 140 holds a content file 221. FIG. 5 shows an example of a content file. The content file 221 includes content location information 4000, a content file name 4010, a content type 4020, a content size 4030, and a content content 4040. Hereinafter, the content location information 4000 and the content file name 4010 are collectively referred to as a content URL 4050 as content identification information.

  FIG. 6 shows a method for requesting content from a content requesting user terminal. In order to acquire the content, the user transmits a user ID 1001, receives authentication from the additional information server 103, and logs in. The user who has performed the login work transmits content request information from the content requesting user terminal 102 to the additional information server 103. The content request information includes a user ID 1001 and a requested content URL 4050.

  The content information transmission / reception function 130 of the additional information server 103 transmits the content URL 4050 transmitted from the content requesting user terminal 102 to the content server 104. The content server 104 searches and extracts the received content URL 4050 from the files included in the content file 221, and transmits the content 4060 having URL information that matches the content URL 4050 to the content information transmission / reception function 130 of the additional information server 103. A reply is made (S602).

  Next, the content information transmission / reception function 130 of the additional information server 103 transmits the user ID 1001 to the user management function 131. The user management function 131 returns the user attribute information and related information (1010 to 1030) corresponding to the user ID 1001 from the user information file 211 to the content information transmission / reception function 130 (S604).

  The content information transmission / reception function 130 of the additional information server 103 transmits the user ID 1001, the content URL 4050, the user attribute information and the relationship information received in step S604 to the additional information association management function 132. The additional information association management function 132 selects and extracts the additional information ID 2040 to be disclosed to the user according to a flow described later, and transmits the extracted additional information ID 2040 to the content information transmission / reception function 130 of the additional information server 103 (S606). ).

  The additional information ID 2040 extracted in step S606 is transmitted to the additional information association management function 132, the corresponding additional information is searched and extracted from the additional information file 213, and returned to the content information transmission / reception function 130 of the additional information server 103. (S608). The content information transmission / reception function 130 of the additional information server 103 transmits the content 4060 extracted in step S602 and the additional information 3010 extracted in step S608 to the content requesting user terminal 102 and publishes them (S610).

  With reference to FIG. 7, how to use the data of each file when the additional information is disclosed will be described. The information used for selecting the additional information includes the additional information disclosure condition 2020 and the additional information target content URL 2000 described in the additional information association management file 212, the user ID 1001 of the user who requests the content, and the information disclosure condition matrix 350. It is. FIG. 8 shows an example of a matrix of information disclosure conditions for additional information. The information disclosure condition matrix 350 includes a relationship 5100 between the additional information and the assigned content, an additional information disclosure condition 5200, and an additional information disclosure status 5300. Using these pieces of information, the additional information association management function 132 searches for additional information IDs to be disclosed. Information that is searched for additional information from the additional information file 213 using the searched additional information ID and transmits the extracted additional information to the user, or additional information NG indicating that there is no information to be disclosed as a result of the search 370 is sent to the user.

  FIG. 9 shows a method in which the additional information association management function 132 selects additional information to be disclosed. Information necessary for selection includes a content URL 4050 of the content file 221, a user ID 1001 of the user information file 211, user attribute information and related information (1010 to 1030). First, the additional information association management file 212 is searched using the content URL 4050, and the disclosure condition of the additional information in which the content URL 4050 and the additional information target content URL 2000 match is searched and extracted. (S702). If there is anything corresponding to the condition of having a matching URL, the selected additional information disclosure condition 2020 is searched (S704).

  If the disclosure condition is an unspecified user, the content type 2010 in the additional information association management file 212 is examined (S706). If the content type 2010 is an original content or related content with similar content, the content is disclosed. In the case of other related contents, it is determined based on the user relationship information 1030 in the user information file 211 whether or not the registered user of the additional information and the content requesting user are in an intimate relationship (S708). If it is a user who has a special relationship, it will be made public, otherwise it will be made private.

  If the publishing condition is a specific user, it is determined whether or not the user ID of the content requesting user is specified in the publishing condition (S710), and if specified, it is disclosed, and if not, it is not disclosed. If the disclosure condition is the user, it is determined whether or not the user ID of the content requesting user is equal to the user ID of the additional information registration user (S712).

  FIG. 10 shows a method for registering additional information from the additional information registration user terminal. The user who has performed the login work transmits additional information registration information from the additional information registration user terminal 101 to the content information transmission / reception function 130 of the additional information server 103 (S802). The additional information registration information includes the content 3010 of the additional information, the additional information target content URL 2000 to which the additional information is added, and the additional information disclosure condition 2020.

  The additional information content 3010 transmitted to the content information transmission / reception function 130, the additional information target content URL 2000, and the additional information disclosure condition 2020 are transmitted to the additional information association management function 132. The additional information association management function 132 refers to the additional information file 213 to newly pay out the additional information ID 2040, adds the additional information ID 2040, the additional information content 3010, the additional information target content URL 2000, and the additional information disclosure condition 2020. Are stored in the additional information file 213 in association with each other (S804).

  Next, the content information transmission / reception function 130 checks the additional information disclosure condition 2020 transmitted from the additional information association management function 132 (S806). When the additional information disclosure condition 2020 is designated as a specific user, the user ID of the disclosure destination included in the additional information disclosure condition 2020 is transmitted to the user management function 131. It is checked whether or not the user ID specified as the disclosure destination is registered in the user information file 211. The check result is returned to the content information transmission / reception function 130. If the user ID is unregistered, the disclosure destination user ID and the additional information target content URL 2000 are transmitted to the mail transmission function 134. The mail transmission function 134 notifies the disclosure destination user ID of additional information using electronic mail (S808).

  When the disclosure condition is a specific user and the user to be disclosed is not an unregistered user, a search is performed for related content that is an expansion destination of additional information association. An example of a related content search method will be described below. When the original content has a logical file structure, the additional information target content URL 2000 is transmitted to the related content search function 133. The related content search function 133 is newly added as a related content that is related to the logical structure of the original content, for example, content that is in a higher-order or parallel relationship with the original content, and is used as an expansion destination of additional information correspondence. The related content URL 2100 is transmitted to the content information transmitting / receiving function 130 (S810).

  In addition, the following method is also conceivable as another method for searching related content. The content information transmission / reception function 130 transmits the additional information target content URL 2000 and the additional information ID 2040 to the related content search function 133. The related content search function 133 extracts the content 4060 from the content server 104 using the transmitted additional information target content URL 2000, and performs semantic analysis of the content content (S812). The additional information association management function 132 includes the contents of the content obtained by the semantic analysis and the contents of the content to which the additional information file 213 of the additional information association management function 132 has been added in the past. Make an inquiry. The URL of related content having contents similar to the content of the additional information target content URL 2000 is searched and extracted, and transmitted to the content information transmission / reception function 130 (S814).

  The URL 2100 of the related content discovered through steps S810 to S814, the original content 2000, the additional information ID 2040, and the additional information disclosure condition 2020 are stored in the additional information association management file 212 of the additional information association related function 132. . These pieces of information are newly associated and stored in the additional information association management file 212 (S816). At this time, the additional information assigned to the original content is associated with the found related content, and the additional information given to the found related content is changed according to the additional information disclosure condition. Is associated with.

  The search for related content described in steps S810 to S814 and the association of additional information in step S816 will be described with reference to FIG. Additional information is given to the URL 1 in the additional information file 213 by the user A, and the related content is searched. An example of URL1 information is shown in the content file 221a. One method of finding content having contents similar to URL1 is a method of finding using the logical structure shown in step S810 of FIG. Here, as an example, URL2 in the upper directory of URL1 is extracted. The information of URL2 is a content file 221b.

  Further, in the case of the method of finding content having related contents shown in steps S812 and S814 in FIG. 5, whether the same keyword is included in the content URL 4050 from the content file 221a (similarity determination example 1), A content to which either of the conditions indicated by the content content 4040 is similar (similarity determination example 2) is extracted. In this way, one of the extracted contents is set as URL3 as content related to URL1. In this way, when URL2 and URL3 associated with URL1 are added to the additional information association management file 212, new association is performed.

  As an example of the content distribution system, let us consider giving additional information to news published on the Internet. The correspondence between additional information and content when news similar in content is published on various news sites on the Internet will be described below.

  FIG. 12 shows a change in the correspondence between the content included in the news sites 710 and 720 published on the Internet and the additional information given to the content. The news site 710 on the Internet includes news 712, news 713, and news 714, and the news site 720 includes news 722. It is assumed that the contents of the news 712 and the news 722 are related. Here, consider a case where the user 701 gives the additional information 702 to the news 712 and sets the disclosure condition of the additional information as an unspecified number. When the additional information 702 and the content are newly associated with each other, the language analysis of the text included in the news 712 is performed, and the language analysis of the news 722 that is a candidate for newly adding the additional information is performed. If it is determined that the contents of the two news are similar, the news 722 can be extracted as content related to the news 712. As a result, the additional information 702 is newly associated with the news 722 as indicated by an arrow 731 in FIG.

  In addition, as a related content extraction method, a case where a logical file structure in which news 712 is stored, for example, a directory structure is used is considered. Here, a case where content existing in a higher directory of original content is handled as related content will be described. By this method, news 713 and news 714 that are included in the news site 710 and are in a directory higher than the news 712 are extracted as contents related to the news 712.

  As an example of a content distribution system, a system for adding additional information to a banner advertisement is conceivable. A system for adding additional information to a banner advertisement is a system in which a user assigns additional information to a banner advertisement displayed in content on the Internet, and causes other users to display the banner advertisement. It is a system that can be viewed at the same time. Further, the additional information given to the banner advertisement is associated not only with the banner advertisement to which the additional information is initially given, but also with the associated banner advertisement so as to be associated with the system and disclosed to the user.

  FIG. 15 shows a method for disclosing additional information for a banner advertisement. Assume that the user 1100 gives additional information 1111 to the displayed banner advertisement 1110. Next, when the user 1101 logs in from the user terminal 1104 and requests content, a banner advertisement 1110 included in the content is requested to the advertisement server 1103 via the additional information server 1102. The additional information server 1102 searches the banner advertisement 1110 for additional information from the additional information management server included in the server, and extracts the additional information 1111. A banner advertisement 1110 is distributed from the advertisement server 1103 to the additional information server 1102. The additional information server 1102 distributes the banner advertisement 1110 and the additional information 1111 to the user terminal 1104 of the user 1101. The user 1101 can browse the additional information 1111 given by the user 1100.

  FIG. 16 shows a method of publishing additional information for a banner advertisement in preference to publicly available additional information. The additional information published to the user himself / herself was inquired of the additional information server, and the additional information that the user himself / herself was made public and the public method of browsing preferentially from the banner advertisement corresponding to this additional information were described. FIG. Consider a case where the user 1200 gives additional information 1211 to the displayed banner advertisement 1210 and designates the user 1201 as a public user. The user 1201 makes a request for browsing additional information designated as a public user to the additional information server 1202 from the user terminal 1204. The additional information server 1202 searches for additional information designated by the user 1201 as a public user, and as a result of the search, additional information 1211 given to the banner advertisement 1210 is extracted. The additional information server 1202 requests the banner advertisement 1210 from the advertisement server 1203, and the advertisement server 1203 delivers the banner advertisement 1210 to the additional information server 1202 in response to the request. The additional information server 1202 delivers the additional information 1211 and the banner advertisement 1210 together to the user terminal 1204 of the user 1201 for display.

  As an example of the content distribution system, FIG. 17 shows a method of disclosing additional information using user attribute information. Consider a case where the user 1300 assigns the additional information 1303 to the content 1304, and designates the condition for specifying the disclosure condition 1310 of the additional information 1303 as “unspecified majority” and “resident in Tokyo”. Further, it is assumed that the content 1304 is content related to “Tokyo Hospital”. At this time, the attribute information of the user who browses the additional information, in this case, the address information of the user, can be used to restrict the disclosure destination of the additional information given by the user 1300. For example, a user 1301 living in Tokyo can browse content 1304 written about hospitals in Tokyo and additional information 1303 assigned thereto. On the other hand, for example, the user 1302 living in Hokkaido cannot view the additional information 1303 because it does not meet the disclosure conditions. In this manner, additional information using attribute information can be disclosed.
