Description

  The present invention relates to a communication terminal on a network such as the Internet or a mobile network, and a service knowledge sharing method for the communication terminal.

  Conventionally, the URL (Uniform Resource Locator) or title of a favorite web page on a website such as a shopping site or an artist's fan site so that the user can easily call it later using a bookmark management tool. , Save information such as comments. Since a Web page provides a certain content or function, information indicating the Web page is referred to as a “service” in this specification. Since bookmarks store services that a user is interested in and services that have been evaluated as useful, it can be said that bookmarks are personal service knowledge. Bookmarks are usually classified and organized hierarchically, and the vocabulary used for the classification is arbitrarily given by the user. Hereinafter, the classification name is referred to as a category name. In addition, information that hierarchically classifies services including category names is called a category. A certain category holds a service list including zero or more services belonging to it, and has zero or more subcategories that belong to lower levels, and constitutes a category hierarchy.

As a service for sharing such service knowledge among a plurality of users, there are online bookmark services such as BLINK (registered trademark) and WebMarky. The user can set a part (category unit) of his service knowledge or the whole to “public”. As a result, the other person can refer to the category, subcategory, and service of the part set to “public” in the bookmark.
However, in such hierarchical service knowledge, the vocabulary and hierarchical structure used for each user differ greatly. The conventional online bookmark service presents the service knowledge of the other person according to the vocabulary and the hierarchical structure of the other person, and there is a problem in usability in reference and organization.

In recent years, data is directly exchanged between terminals without using a server, such as peer-to-peer communication and distributed communication. For this reason, each communication terminal shares service knowledge by directly exchanging service knowledge held in its own terminal with other communication terminals. However, there is a problem that it is difficult for the user of each communication terminal to use the service knowledge of the other person with ease of use even if the service knowledge of the other person is completely different from the concept system managed by the own terminal. .
On the other hand, a technique for sharing hierarchical service knowledge among users using a common concept system has been proposed (for example, Patent Document 1).
JP 2001-297022 A (paragraphs 0029 and 0030) “BLINK” [online], [Search April 12, 2004], Internet <URL: http://www.blink.jp> “WebMarky” [online], [April 12, 2004 search], Internet <URL: http://www.webmarky.com/>

  However, in Patent Document 1, it is assumed that user service knowledge is centrally managed by a server, and all users use the same conceptual system managed by the server. Therefore, when it is assumed that service knowledge having a different concept system is managed for each communication terminal as described above, the above-described problem can be solved even by using the technique described in Patent Document 1. I can't do it.

In addition, even if the service knowledge held by the communication terminal is updated by another person, it is not automatically notified. Therefore, it is difficult to immediately use the service knowledge of the other person. Furthermore, in the past, only a means of controlling access to whether a specific level of service knowledge is disclosed to an unspecified person or privately provided is provided to a specific person such as a family member or a friend. A fine-grained access control means such as opening up a hierarchy has not been provided.
The present invention has been made in view of the above problems, and a communication terminal and a service that can share service knowledge of different conceptual systems managed for each user's communication terminal in an easy-to-use manner for each user. It is an object to provide a knowledge sharing method.

  In order to solve the above problem, the invention according to claim 1 is a service knowledge holding means for storing service knowledge including a category for classifying services hierarchically and a service included in the category, and the service.

The service knowledge synthesis means performs the synthesis process for synthesizing the service knowledge of the other person with the service knowledge stored in the service knowledge holding means, so that it matches the conceptual system of the own service knowledge managed by the own terminal. Thus, it is possible to perform a synthesis process of the service knowledge of the self and the service knowledge of others. Therefore, the user can refer to and organize the service knowledge of others with different concept systems in accordance with his / her concept system. Therefore, it is possible to easily share service knowledge with different conceptual systems managed for each user's communication terminal for each user.

  According to a second aspect of the present invention, in the communication terminal according to the first aspect, the synthesizing process performed by the service knowledge synthesizing unit is based on a result of comparison by the matching unit. When it is determined that the specific category has the same concept as the specific category of the self stored in the service knowledge holding means, the service included in the specific category of the other person is changed to the specific category of the self. Subcategories belonging to a lower layer of the specific category of the other party among the categories included in the service knowledge of the other person and stored in the service knowledge holding means as a service included in the specific category of the self It is a process which memorize | stores in the said service knowledge holding means as a subcategory.

  According to the present invention, in the combining process performed by the service knowledge combining means, a specific category of the other person included in the service knowledge of the other person is stored in the service knowledge holding means based on the comparison result by the matching means. If the concept is determined to be equal to the specific category of the user, the service knowledge holding means includes a list of services included in the specific category of the other person, and the service included in the specific category of the self. And storing a subcategory belonging to a lower layer of the specific category of the other person as a subcategory of the specific category of the self among the categories included in the service knowledge of the other person. Therefore, the communication terminal performs a synthesis process of the service knowledge of the other person and the service knowledge of the self in accordance with its own conceptual system. Door can be. For this reason, the user can use the service knowledge of others according to his or her own conceptual system with ease of use.

  According to a third aspect of the present invention, in the communication terminal according to the first or second aspect, the synthesizing process performed by the service knowledge synthesizing unit is included in the service knowledge of the other person based on a comparison result by the matching unit. When it is determined that the specific category of the person is a subordinate concept with respect to the specific category of the self stored in the service knowledge holding means, the specific category of the other person and the other person's Among the categories included in service knowledge, the subcategory belonging to a lower layer of the specific category of the other person is stored in the service knowledge holding means as a subcategory of the specific category of the self. .

  According to the present invention, in the combining process performed by the service knowledge combining means, a specific category of the other person included in the service knowledge of the other person is stored in the service knowledge holding means based on the comparison result by the matching means. A specific category of the other person and a category included in the service knowledge of the other person among the specific category of the other person and the specific category of the other person Since it is a process of storing the subcategory belonging to the lower layer of the category in the service knowledge holding means as a subcategory of the specific category of the self, the communication terminal can match the service knowledge of others with the self-concept system. Synthesizing with your service knowledge is possible. For this reason, the user can use the service knowledge of others according to his or her own conceptual system with ease of use.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
[1. Constitution]
FIG. 1 shows a configuration example of a system according to an embodiment of the present invention.
As shown in the figure, this system includes a communication terminal 1 that holds service knowledge of a user, a partner communication terminal 2 that holds service knowledge of a user's communication partner, and an ontology that holds ontology information related to a vocabulary conceptual system. The database device 3 is included, and each device is connected to the network by a wired network or a wireless network.

The communication terminal 1 and the partner communication terminal 2 may be a mobile phone, a PDA (Personal Digital Assistance), a notebook PC (Personal Computer), or a desktop PC. The communication terminal 1 and the partner communication terminal 2 hold service knowledge based on a user's original concept system. And the communication terminal 1 and the other party communication terminal 2 share service knowledge by mutually transmitting / receiving service knowledge.
In the figure, only one partner communication terminal 2 is shown as a communication partner device of the communication terminal 1, but there are actually a plurality of other devices. In the following explanation, “service knowledge”, “category”, “subcategory”, “service”, “service list”, and “category list” represent data when these are transmitted or stored. And

[1.1. Configuration of communication terminal]
Next, the configuration of the communication terminal 1 will be described. The communication terminal 1 includes a CPU (Central Processing Unit), a storage unit including a volatile memory and a nonvolatile memory, a communication interface for controlling communication, a display for displaying various screens, and operation buttons for giving various commands to the CPU. And has a computer hardware configuration. The storage unit of the communication terminal 1 stores software such as various programs and data. The functions shown in FIG. 2 are realized in the communication terminal 1 by the cooperation of these software and hardware.

  The communication unit 101 is a module for communicating with the counterpart communication terminal 2 and the ontology database device 3, and the communication method may be any method such as wired / wireless, packet, or line switching. The bus 102 is a communication path for each internal functional block. The control management unit 103 is configured to include a CPU, and controls execution of a procedure according to the flowchart shown below, and controls each functional block by using the timer 104 as an auxiliary. The input unit 105 includes an operation button, and transfers information corresponding to the operated operation button to each functional block. The output unit 106 includes a display, and displays various screens by receiving information from the service knowledge presentation unit 119.

The service knowledge holding unit 107 includes service knowledge stored in a nonvolatile memory. Service knowledge is information managed by the user's own vocabulary and conceptual system. The service knowledge includes a category for classifying services hierarchically and a service included in the category.
FIG. 3 shows an example of the data structure of service knowledge. As shown in the figure, the service knowledge includes a “category”, a “service list” that is a list of services included in the category, and a “subcategory” that is a category that belongs to a lower layer of the category. The data structure of the service knowledge shown in FIG. 3 is an example, and what is the service knowledge as long as it is information that represents the category name, the list of services belonging to the category, and the hierarchical relationship between the categories. A simple data structure may be used. For example, the information related to the hierarchical relationship between categories may be information about higher-level categories instead of information about subcategories.

FIG. 4 is a diagram conceptually showing hierarchical service knowledge. As shown in the figure, service knowledge is configured by hierarchically connecting categories holding a list of services. A view as illustrated in FIG. 4 is generated based on the service knowledge illustrated in FIG. 3 and is output to the output unit 106.
The service knowledge response unit 112 returns the service knowledge stored in the service knowledge holding unit 107 in response to a service knowledge request received from another communication terminal.

The communication partner management unit 110 manages a list of identification information of communication terminals to be notified of update information about service knowledge stored in the nonvolatile memory. The identification information here is a communication address such as an IP (Internet Protocol) address or a telephone number. The communication partner management unit 110 includes a service unit communication partner management function 1101 and a category unit communication partner management function 1102, and manages a notification partner of update information in service units or category units. Further, when the service knowledge response unit 112 responds to a service knowledge request from another communication terminal, the communication partner management unit 110 can notify update information to the other communication terminal in the future. In addition, identification information of other communication terminals is stored.
The update receiving unit 114 acquires update information from the counterpart communication terminal 2 via the communication unit 101.

Next, the functional blocks realized by the CPU executing the program will be mainly described below.
When the service knowledge stored in the service knowledge holding unit 107 is updated, the update notification unit 115 sends information about the updated service knowledge to the communication terminal managed as the communication partner by the communication partner management unit 110. Send update information.
The service knowledge acquisition unit 113 acquires the service knowledge that is disclosed by the counterpart communication terminal 2 from the counterpart communication terminal 2 via the communication unit 101. As an acquisition method, the service knowledge acquisition unit 113 periodically transmits a service knowledge request to the partner communication terminal 2 that is managed as a communication partner by the communication partner management unit 110. Get knowledge. Alternatively, when the service knowledge acquisition unit 113 detects an instruction to acquire service information from the input unit 105, the service knowledge acquisition unit 113 acquires the service knowledge request by transmitting it to the counterpart communication terminal 2.

  The matching unit 108 compares the concept of the category stored in the service knowledge holding unit 107 and the category included in the service knowledge acquired from the partner communication terminal 2. Specifically, the matching unit 108 selects one category from each of all categories stored in the service knowledge holding unit 107 and all categories of communication partners acquired from the partner communication terminal 2. To do. The matching unit 108 transmits the category names of the two selected categories to the ontology database device 3 that holds the vocabulary concept system. Based on the result returned from the ontology database device 3, the matching unit 108 determines whether the category of the communication partner received from the partner communication terminal 2 is conceptually equal to its own category or conceptually lower. to decide. Here, a case where the category of the other party is conceptually equal to the user's category or conceptually located at a lower level is called “match”. The matching unit 108 inspects the concept of the category by matching the combinations of all of its own categories and all of the categories of the communication partner.

Instead of inquiring the ontology database device 3, the matching unit 108 may store ontology information in the terminal 1 and determine the conceptual relationship between the two categories in the terminal 1.
The service knowledge synthesis unit 109 synthesizes the service knowledge of the partner acquired from the partner communication terminal 2 into the service knowledge stored in the service knowledge holding unit 107 based on the concept comparison result by the matching unit 108. Process.

  Specifically, the “synthesis process” refers to the following process. When the matching unit 108 determines that the specific category of the partner is equal in concept to the specific category of the partner, the service knowledge synthesis unit 109 selects the service included in the specific category of the partner as the specific category of the partner. The service is stored in the service knowledge holding unit 107 as a service included in the category. Further, the service knowledge synthesizing unit 109 sets the subcategory belonging to the lower layer of the specific category of the partner among the categories included in the acquired service knowledge of the partner as the subcategory of the specific category to the service knowledge holding unit 107. Remember.

  On the other hand, when the matching unit 108 determines that the specific category of the partner is a concept lower than the specific category, the service knowledge synthesis unit 109 acquires the specific category of the partner and the acquisition Of the categories included in the service knowledge of the partner, the subcategory of the specific category of the partner is stored in the service knowledge holding unit 107 as a subcategory of the specific category of the partner.

  Further, the service knowledge synthesizing unit 109 includes a multi-match corresponding synthesizing function 1091 and a non-match synthesizing function 1092. As described above, the matching unit 108 compares the concept of another category with each of its own categories stored in the service knowledge holding unit 107. The multiple match correspondence synthesis function 1091 performs a synthesis process for its own category based on each comparison result by the matching unit 108. Therefore, when the category of the other party matches a plurality of own categories stored in the service knowledge holding unit 107, the composition processing is performed on the own categories as many times as the number of matches.

  The non-matching composition function 1092 is that the specific category of the partner included in the service knowledge of the partner is not equal in concept to any of the own categories stored in the service knowledge holding unit 107, and is not a subordinate concept. In this case, that is, when there is no match, the category name of the specific category of the partner is changed to a new category name, and the specific category of the partner is stored in the service knowledge holding unit 107. Alternatively, the non-matching combination function 1092 may generate a new category and store the specific category of the other party in the service knowledge holding unit 107 as a subcategory of the new category.

Note that the above-described combining process is an example, and for example, the user can easily refer to his / her conceptual system as appropriate, for example, limiting the subcategory of the partner to be added as a subcategory of his / her category only to the next lower hierarchy. Can be adjusted as follows.
The disclosure state management unit 117 stores disclosure state management information in a nonvolatile memory. The disclosure state management information is information for managing whether to disclose service knowledge to a user or a group composed of a plurality of users in units of categories. That is, the open state management information is information indicating, for each category, whether or not to permit transmission of the category to the user communication terminal.

The access control unit 111 determines whether to respond to the partner communication terminal 2 that has transmitted the service knowledge request, based on the public state management information stored in the public state management unit 117.
The service knowledge editing unit 118 adds, deletes, and corrects service knowledge stored in the service knowledge holding unit 107. For example, the service knowledge editing unit 118 changes the name of a category or deletes a category or service based on information input from the user input unit 105.

  The service knowledge presentation unit 119 generates information for displaying a screen based on the service knowledge stored in the service knowledge holding unit 107 and outputs the information to the output unit 106. Thereby, service knowledge can be presented to the user in a tree format as shown in FIG. Further, immediately after receiving the update information from the counterpart communication terminal 2, the service knowledge presentation unit 119 outputs the category and service included in the update information to the output unit 106. Thereby, update information can be immediately presented to the user.

[1.2. Ontology database device]
The ontology database device 3 is a PC, workstation, server, or the like, and has a general computer hardware configuration. A database is provided in the hard disk of the ontology database device 3, and ontology information is stored in the database.

  The ontology database device 3 accepts two category names as parameters from the communication terminal 1 and whether the two category names are conceptually equal or whether a certain category name is conceptually lower than one category name. Or whether it is neither of them. Specifically, when the ontology database device 3 receives the category names “music” and “music”, the ontology database device 3 responds that the vocabulary of “music” and “music” is conceptually equal. Further, when the ontology database device 3 receives the category names “music” and “jazz”, it responds that “jazz” is a subordinate concept of “music”. Further, when the ontology database device 3 receives the categories “music” and “rock”, the ontology database device 3 responds that “rock” is a subordinate concept of “music”. The functions of the ontology database device 3 are realized by the CPU of the ontology database device 3 executing a program.

[2. Operation]
Next, the operation in the above configuration will be described. As a premise, the service knowledge holding unit 107 of the communication terminal 1 is assumed to store service knowledge having the contents shown in FIG. Further, it is assumed that the service knowledge holding unit 107 of the partner communication terminal 2 stores service knowledge having the contents shown in FIG.

[2.1. Service knowledge synthesis process]
FIG. 5 is a flowchart showing the procedure of the service knowledge synthesis process. A synthesizing process procedure for synthesizing service knowledge between the communication terminal 1 and the partner communication terminal 2 will be described with reference to FIG.
Here, the disclosure state management unit 117 of the partner communication terminal 2 discloses that all categories except the category “Diet” among the categories stored in the service knowledge holding unit 107 are disclosed to the communication terminal 1. Assume that public status management information is stored.
This procedure is performed when, for example, the user operates the button of the communication terminal 1 to instruct “service knowledge synthesis” while referring to the service knowledge displayed on the output unit 106 of the communication terminal 1. Is activated (step S101).

The user designates one or more communication addresses of communication terminals for which service knowledge should be requested from the input unit 105 as communication partners (step S102). Here, it is assumed that the partner communication terminal 2 is designated as the communication terminal that should request service knowledge.
The communication partner management unit 110 stores a list of communication addresses of communication partners input by the user (step S103). And the service knowledge acquisition part 113 of the communication terminal 1 transmits the service knowledge request | requirement for requesting service knowledge with respect to the other party communication terminal 2 (step S104).

The access control unit 111 of the counterpart communication terminal 2 extracts all categories disclosed to the requesting communication terminal 1 from the disclosure state management unit 117, and creates a category list that is a list of category names ( Step S105).
Here, since all categories except “Diet” are open to the requester, the category list to be created (hereinafter referred to as “Category List 2”) includes “Cooking”, “The Artist 1”, Includes 'fan site', 'bulletin board', 'shopping', 'accessories', 'cosmetology'.

The communication partner management unit 110 of the partner communication terminal 2 adds the communication address of the communication terminal 1 to the notification partner list and stores it (step S106).
Then, the service knowledge response unit 112 of the counterpart communication terminal 2 returns service knowledge including the category list 2 and the service list included in the category to the service knowledge acquisition unit 113 of the requesting communication terminal 1 (step S107). ).

  The service knowledge acquisition unit 113 receives the category list 2 from the counterpart communication terminal 2. The matching unit 108 of the communication terminal 1 acquires the category list 2 from the service knowledge acquisition unit 113, and further, from the service knowledge holding unit 107, its own category list “scuba”, “lock”, “artist 1”, “artist 2”. ',' Fashion ',' Bag / Shoes' (hereinafter referred to as "Category List 1") are acquired. Then, the category name included in the opponent category list 2 and the category name included in the user's category list 1 are selected one by one (step S109), and whether they are conceptually equal or conceptually subordinate. Is sent to the ontology database device 3 (step S110).

The ontology database device 3 accepts two category names as parameters, whether the two category names are conceptually equal, or whether the partner category name is conceptually lower than their own category name. It is determined whether or not there is a response, and the result is returned (step S111).
The service knowledge synthesizing unit 109 of the communication terminal 1 adds the service list included in the category of the partner that the matching unit 108 determines to be conceptually equal, and the subcategory that is a category in the lower layer to the corresponding own category. The information is stored in the service knowledge holding unit 107 (step S112; yes, step S113).

  Here, the ontology database device 3 determines that “artist 1” in category list 1 and “The Artist 1” in category list 2 are conceptually equal. Then, as shown in FIG. 6C, the service 14 included in “The Artist 1” of the category list 2, the “fan site” and the “bulletin board” which are subcategories of “The Artist 1”, and the services included in them. 5, 6, 7, 8, and 9 are also added to the category of “Artist 1” in the category list 1 together. Accordingly, the service 14 is added so as to be included in the category “artist 1”, and the categories “fan site” and “bulletin board” are added as subcategories of the category “artist 1”.

On the other hand, the service knowledge synthesizing unit 109 adds the category of the other party that the matching unit 108 has determined to be conceptually positioned as a subcategory of the corresponding own category, and stores the information in the service knowledge holding unit 107 ( Step S114; yes, Step S115).
Here, it is determined that “accessories” and “cosmetics” in the category list 2 are located in a lower layer of “fashion” in the category list 1, and are added as subcategories of “fashion” as shown in FIG. The
When a specific category of the other party in the category list 2 matches a plurality of categories, the multi-match compatible combining function 1091 performs a combining process on each of the plurality of categories. At this time, the communication terminal 1 may notify the partner communication terminal 2 that the specific category of the partner has several meanings in its conceptual system.

  As a modification, it is also possible to add only appropriate services to each of a plurality of matched categories by using metadata such as the titles and comments of each service. For example, if your category list 1 contains two category names, 'Artist 1' and 'Artist 3', and your opponent's category list 2 contains 'The Artist 1 & The Artist 3', The concept matches both my category names 'Artist 1' and 'Artist 3'. At this time, the service knowledge synthesis unit 109 adds only the service related to “The Artist 1” to the category of “Artist 1”, and selectively selects only the service related to “The Artist 3” to the category of “Artist 3”. Perform the synthesis process to be added to

  Further, the non-matching synthesis function 1092 of the service knowledge synthesis unit 109 creates a special category when the partner's category is not equal to the user's category and is not positioned at the lower level, that is, when it does not match. And synthesize it with your service knowledge. The category name of the special category can include the name of the other party, 'other', 'new category', and the like. Users can continue to use new categories and services added to the special category, change the category name to match their vocabulary, or delete the category if not needed. Good. These operations are performed by the service knowledge editing unit 118. In this way, the user can acquire a new concept (category) from another person.

Finally, when the matching unit 108 matches all combinations and completes the inspection (step S116; yes), the service knowledge presenting unit 119 generates a display screen based on the synthesized service knowledge, and FIG. It is presented to the user in a tree format as shown in c) (step S117).
Accordingly, the user can refer to the service knowledge of the other person based on his / her conceptual system, and can use the service knowledge of the other person with ease of use for the user.

[2.2. Service knowledge update notification procedure]
FIG. 7 is a flowchart showing a procedure for notifying update information when service knowledge is updated in the partner communication terminal 2. The update information notification procedure will be described with reference to FIG.
Here, by performing the service knowledge synthesis processing procedure described above, the category unit communication partner management function 1102 of the communication partner management unit 110 of the partner communication terminal 2 performs communication of the communication terminal 1 as a communication partner of the category “cosmetics”. Assume that addresses are managed. Here, it is assumed that communication partners are managed only in units of categories.

First, the service knowledge editing unit 118 adds a new service or category to the service knowledge holding unit 107 and adds an existing service or category based on a service knowledge editing command from the input unit 105 by the user (step S201). Deletion is performed (step S202). The service knowledge holding unit 107 stores the updated service knowledge (step S203).
When this update is performed, the update notification unit 115 creates update information including the changed category and service list (step S204).

  Then, the access control unit 111 extracts the communication address of the communication terminal included in the communication partner list from the communication partner management unit 110 (step S205). Based on the extracted communication address and the created update information, the access control unit 111 publishes the category to which the updated service belongs or the updated category to the communication terminal having the extracted communication address. It is determined whether or not (step S206).

  Here, for example, as shown in FIG. 6 (b), when the service 13 is added to the category “cosmetics” stored in the service knowledge holding unit 107 of the counterpart communication terminal 2, the service 13 belongs. Since the “cosmetics” category is open to the communication terminal 1 (step S207; yes), the update notification unit 115 of the partner communication terminal 2 indicates that the service 13 has been added to the “cosmetics” category. Update information is notified to the communication terminal 1 (step S208).

In the notification destination communication terminal 1, the update receiving unit 114 receives the update information (step S209), and the service knowledge editing unit 118 reflects the update information in the service knowledge holding unit 107 (step S210). The service knowledge holding unit 107 holds the updated service knowledge (step S211).
The service knowledge presentation unit 119 presents update information to the user (step S212). Here, the service knowledge presenting unit 119 presents that the service 13 has been added to the “cosmetics” category. When the user refers to service knowledge, the service knowledge presentation unit 119 presents the latest service knowledge.

  As described above, when the service knowledge of the partner communication terminal 2 is updated, the partner communication terminal 2 immediately notifies the communication terminal 1 of the update information, so that the user of the communication terminal 1 immediately knows the service knowledge of others. Can be used. This eliminates the need for the user to confirm whether or not the service knowledge published by others has been updated. Furthermore, the information managed by the communication partner management unit 110 enables fine-grained access control such as opening a certain category or service only to a specific person such as a family member or a friend. Even when personal interests and preferences are included, users can share services without resistance.

  As a modification, instead of notifying the communication terminal 1 of the update information by push from the partner communication terminal 2 that has updated the service knowledge as described above, the communication terminal 1 periodically inquires the partner communication terminal 2 about the update information. It may be. As another modification, even when a service is added to a certain communication terminal, if a communication terminal designated as a notification partner of update information sets the notification to be unnecessary, an update notification of a certain communication terminal The unit 115 can select not to notify in order to reduce traffic.

As described above, according to the present invention, the user can refer to the service knowledge of the other person based on the concept system having his / her vocabulary and hierarchical structure, so that the service knowledge of the other person is easy to use for the user. Can be used. In addition, when the same category or service is updated again in the communication terminal that has received notification of service knowledge, the communication terminal 1 can immediately receive notification. Furthermore, since access restrictions on categories can be set for specific users or groups, it is possible to finely control which knowledge is disclosed to whom, and promote service sharing among users.
In this way, dynamically updated personal service knowledge such as bookmarks can be shared among users while maintaining the personal conceptual system and the latest state.

  It can be used for synthesizing a conceptual system of hierarchical service knowledge such as bookmarks and sharing information in a distributed system.
