Can also be stored as metadata association structure data. According to this configuration, the user information management means (26) for storing user information (features, profiles) for each user of the client terminal as metadata association structure data is provided, so that a navigation route for each user is set. Therefore, the navigation route can be dynamically changed according to history information such as user preferences and purchase history.
[0013]
Also, the metadata server (30) stores the metadata-related information and the metadata association structure data separately (without associating), and the metadata editing means (25a) The association structure between the metadata may be dynamically edited by combining (associating) with the association structure data of the metadata.
[0014]
The content management server (20) further includes a display information generation means (23) for generating display information to be displayed on the client terminal, and a style sheet database (style sheet database for storing the style sheet for generating the display information in a predetermined format). 231), the style sheet includes a content display area (1101), a display area (1102) of an association structure between metadata for the content, a search keyword input area (1103), and a search result display area (1104) may be included. A WWW browser can display a screen divided into several screens (frames). By dividing each display / input area into, for example, this frame and displaying it, even when displaying information that does not fit in one area, the display contents can be switched individually, improving usability. .
[0015]
Further, the client terminal (10), the content management server (20), the metadata server (30), and the content server (40) may be connected to each other via an information communication network. For example, the content management server (20), the metadata server, and the content server (40) can be mounted on a single integrated server device. However, as in this application example, information such as the Internet or an intranet is used. You may make it connect in the state spaced apart spatially via a communication network.

[0025]
(First embodiment)
FIG. 1 is a diagram showing an arrangement relationship on the information communication network constituting the content management system according to the present embodiment. FIG. 2 is a block diagram schematically showing the configuration of a system that implements the content management system according to the present embodiment.
[0026]
As shown in FIG. 2, the content management system 1 according to the present embodiment relates to a content management server 20 that responds to a communication request from the client terminal 10 and metadata control according to a request from the content management server 20. A metadata server 30 that transmits and receives information and a content server 40 that transmits and receives information related to control of content data in response to requests from the content management server 20 and the metadata server 30 are also included. Below, each component of the content management system 1 is demonstrated in detail.
[0027]
(Content management server 20)
The content management server 20 includes a communication unit 21 that establishes communication between the content management server 20 and the browser 11 on the client terminal 10, a management unit 22 that controls data processing procedures on the content management server 20, and a style. Display information generating means 23 for generating display information to be displayed on the browser 11 using a sheet database (style sheet DB) 231, metadata searching means 24 for searching the metadata server 30 for metadata, and metadata It includes metadata editing means 25 that performs editing processing of metadata acquired from the server 30. The function of each component of the content management server 20 will be further described later.
[0028]
(Metadata server 30)
The metadata server 30 includes a metadata management unit 31 that controls a metadata database (metadata DB) 311 that holds metadata.
[0029]
(Content server 40)
The content server 40 includes content management means 41 that controls a content database (content DB) 411 that holds content data.
[0030]
The content management system 1 according to the present embodiment is configured as described above. Next, details of functions of each component of the content management server 20 will be described with reference to FIGS. 2 to 12 and an operation of the content management system 1 will be described. First, an operation for displaying metadata and content data on the client terminal 10 will be described using the flowchart of FIG.
[0031]
(Communication means 21, step S101)
In response to a connection request from the browser 11, which is a user interface (screen) on the client terminal 10, the communication means 21 uses a communication protocol such as TCP / IP (Transmission Control Protocol / Internet Protocol) or HTTP (Hyper Text Transfer Protocol). Based on this, a session is established (step S101). Here, the browser 11 can be realized by using Web browser software such as Internet Explorer (trademark of Microsoft Corporation) equipped with a Web browser function.
[0032]
(Management means 22)
The management means 22 controls the exchange of data between each means such as passing session information to the display information generating means 23.
[0033]
(Display information generating means 23, steps S102 to S104)
The display information generation unit 23 receives session information through the management unit 22, and calls a style sheet corresponding to the session information from the style sheet DB 231 (step S102). Next, according to the session information, the metadata and the content data are called through the metadata management means 31 and the content management means 41, and these data are arranged in the style sheet (step S103). The style sheet thus arranged is displayed on the browser through the management means 22 and the communication means 21 (step S104).
[0034]
The style sheet can be realized by a conventionally known description method such as XSL (eXtensible Style (Stylesheet) Language).
[0035]
Here, a display example of the stylus sheet is shown in FIG. FIG. 4 is an example of a display form of the browser 11 on the client terminal 10. In this example, in order to display information resources such as HTML document data, text data, and image data acquired through the content management means 41, content data is set at the position of the content data display window 1101 on the style sheet, and metadata management is performed. In order to display the metadata acquired through the means 31, the metadata is set at the position of the explanation route window 1102 on the style sheet.
[0036]
FIG. 5 shows an example of metadata set in the explanation route window 1102. In this example, the navigation route is formed in the order of “basic knowledge about products” → “introduction of each product” → “price of each product” → “notes on contract”. Note that the display of metadata can be visualized and expressed by a graphical user interface (GUI) such as a button.
[0037]
The user of this system displays the content data associated with the metadata on the content data display window 1101 by designating the metadata displayed on the explanation root window 1102 using an input device such as a mouse. To do. By repeating this operation, for example, the display of content data is sequentially switched by designating metadata according to the display order of metadata displayed on the explanation route window 1102 by the user. By using such a usage method, the metadata displayed on the explanation route window 1102 can function as navigation that plays a facilitating role for explaining the content.
[0038]
By the way, when the user requests the display of contents different from the navigation order and items displayed on the explanation route window 1102, it is used by a method other than selecting an item displayed on the explanation route window 1102 such as a search. Need to find content. However, if the contents found by such means are not made to correspond to the items on the explanation route window 1102, the inconvenience of having to search again when the system is used next time arises.
[0039]
Next, an operation for adding metadata and content data to the above-described navigation function and dynamically changing navigation items through interaction with the user will be described with reference to the flowchart of FIG.
[0040]
(Metadata search means 24, steps S201 to S203)
When the user requests an item not included in the navigation items displayed on the explanation route window 1102, the user inputs the explanation item to be requested to the search window 1103 on the browser of the client terminal in FIG. 4 (step S201). The metadata search unit 24 receives the request item, and searches the metadata DB for an item corresponding to the request item through the metadata management unit 31 (step S202). Then, the search result is displayed in the search result display window 1104 of FIG. 4 (step S203).
[0041]
FIG. 6 shows a display screen of the search result display window 1104. FIG. 6A shows the search result of the search result based on the search keyword “example”. As the search result, “use case list”, “individual user case”, “business use” are shown. "Examples of employees" and "Introduction of cases by age" are listed. FIG. 6B shows an inquiry screen for associating search results, which can be selected with a “Yes” or “No” button for an inquiry as to whether or not to perform an association. .
[0042]
(Metadata editing means 25, steps S204 to S206)
As shown in FIG. 6A, an item to be added to the navigation item is selected for the search result displayed in the search result display window 1104. As shown in FIG. 6B, the metadata editing means 25 transmits inquiry information for user selection. That is, the user is inquired whether to associate the item selected from the search results displayed in the search result display window 1104 with the content currently displayed in the content data display window 1101 (step S204). In response to this, the user transmits response information for the inquiry information. Specifically, the “Yes” and “No” buttons shown in FIG. 6B are selected by an input means such as a mouse or a keyboard. When the user selects to associate (“Yes” is selected) (step S205), the metadata editing means 25 displays the content metadata currently displayed in the content data display window 1101 and the search result. A link is made to the metadata of the item selected from (Step S206).
[0043]
This operation will be described in more detail with reference to the description examples of FIGS. 8 to 10 and FIG. The link processing between metadata performed in this embodiment uses, for example, XTM (XML Topic Maps: ISO13250: http: //www.topicmaps.org/xtm/1.0/) which is an XML application standard. Can be realized. This standard is a description language for defining metadata called "topics" and relationships (relationships) between metadata, and provides a model and grammar for the structural representation of information resources.
[0044]
FIG. 8 is an example of metadata description referred to as the above-mentioned topic. (A) is a description example of a topic “kabushiki” representing “stock”, (b) is a topic “gaiyou” representing “stock overview”, and (c) is a description example of a topic “tesuuryou” representing “stock fee”. . Each topic is metadata including information such as a topic identifier 6001, a topic name 6002, and storage 6003 in an information resource entity. FIG. 9 and FIG. 10 show the association between metadata, and details will be described later. FIG. 11 schematically shows the configuration of metadata. In FIG. 11, the entire topic of FIG. 8A and the like is represented by reference numeral 7001, and the topic indicating the information resource entity surrounded by the occurrence tag of FIG. 8A is represented by reference numeral 7002.
[0045]
The association between metadata in XTM can be realized by a description enclosed by association tags shown in FIG. In this description method, the association type is denoted by reference numeral 6004, the type format of the topic located at the upper level is denoted by reference numeral 6005, the topic body is denoted by reference numeral 6006, the type format of the topic located at the lower level is denoted by reference numeral 6007, and It can be described / implemented as reference numeral 6008.
[0046]
That is, the topic “kabushiki” in FIG. 8A is positioned above the topic “gaiyou” in FIG. 8B, and the topic “gaiyou” in FIG. 8B is the topic “kabushiki” in FIG. ”Can be described as a relationship model between two-way topics. In this embodiment, this relation model is implemented as a navigation model. That is, by connecting the relationships between topics, a route 7007 connecting topics 7003 to 7006 from all topics can be implemented as a navigation route as shown in FIG.
[0047]
In such a related model, a topic searched and acquired by a user is incorporated into an existing navigation route. That is, to incorporate the topic “tesuuryou” of FIG. 8C into the related model of FIG. 9 can be easily realized by inserting the topic element into the contents of the association tag as shown in FIG. In this example, the topic identifier shown in FIG. 8C is inserted at the position “S” in the figure.
[0048]
In other words, this is synonymous with the fact that a new association of the route 7010 in FIG. 12 can be realized, and the navigation route 7007 can be immediately changed from 7003 → 7004 → 7011 → 7012 → 7005 → 7006 in response to a request from the user. It becomes possible. The change of the content of the association tag can be realized by DOM (Document Object Model: http://www.w3.org/DOM/DOMTR#doml) which is a conventionally known method.
[0049]
(Effects of the first embodiment)
As described above, according to the present embodiment, the communication means 21, the management means 22, the display information generation means 23, the metadata search means 24, the metadata editing means 25, the metadata management means 31, By providing the content management means 41, by dynamically changing the metadata structure in an interactive manner, a route pattern that refers to content different from the default navigation route can be immediately reflected at the next navigation. Therefore, the navigation route can be expanded flexibly. As a result, the user can customize the menu configuration, so that the usefulness of content use can be improved.
[0050]
(Second Embodiment)
In the content management system 1 according to the first embodiment described above, when the user requests a route different from the default navigation route, the newly selected navigation route can be dynamically constructed interactively. An example of a method for constructing a navigation route has been described. In this embodiment, a navigation system for content that is highly useful for each user can be provided by dynamically constructing a navigation route for each user. There is. An example of this will be described in the second embodiment.
[0051]
The content management system 2 according to the present embodiment will be described with reference to FIG. As shown in FIG. 13, the content management system 2 includes a content management server 20a that responds to a communication request from the client terminal 10 and a meta that transmits and receives information related to metadata control in response to a request from the content management server 20a. The data server 30a includes a content server 40 that transmits and receives information related to control of content data in response to requests from the content management server 20a and the metadata server 30a. Below, each component of the content management system 2 is demonstrated in detail.
[0052]
(Content management server 20a)
The content management server 20a includes a communication unit 21 that establishes communication between the content management server 20a and the browser 11 on the client terminal 10, a management unit 22 that controls data processing procedures on the content management server 20a, a style Display information generating means 23a for generating display information to be displayed on the browser 11 from the sheet database (style sheet DB) 231, metadata editing means 25a for editing metadata, and users holding information for each user It includes a user information management means 26 that exchanges information from the profile 261. The function of each component of the content management server 20a will be further described later.
[0053]
(Metadata server 30a)
The metadata server 30a has metadata management means 31a that controls the metadata DB 311a that holds metadata.
[0054]
(Content server 40)
The content server 40 includes content management means 41 that controls the content DB 411 that holds content data.
[0055]
The content management system 2 according to the present embodiment is configured as described above. Of the above components, the communication means 21, the management means 22, and the content management means 41 constituting the content server 40 of the content management system 20a can be configured in the same manner as in the first embodiment. Therefore, the operations of the user information management means 26, the metadata editing means 25a, the display information generating means 23a, and the metadata server 30a, which are different from the first embodiment, will be described below.
[0056]
The operation of the second embodiment will be described below based on the block diagram of FIG. 13 and the flowchart of FIG.
[0057]
(User information management means 26, steps S301 to S303)
First, it is determined whether or not the user is a new user. That is, it is determined whether the process is for a user registered in advance in the user profile 261 (step S301). Here, an example of processing for a user registered in advance in the user profile 261 will be described. The user information management unit 26 acquires information such as the user ID and password of the user from the client terminal 10 through the communication unit 21 and the management unit 22 (step S302). Based on the acquired information, the user information stored in advance is retrieved from the user profile 261 and acquired (step S303).
[0058]
(Metadata editing means 25a, steps S304 to S305)
The metadata editing unit 25a acquires user profile information from the user information management unit 26, and acquires association structure data stored as information corresponding to the profile information from the metadata DB 311a through the metadata management unit 31a. (Step S304). At the same time, the metadata editing unit 25a acquires metadata group information from the metadata DB 311a through the metadata management unit 31a (step S305).
[0059]
Here, the above mentioned XTM (XML Topic
When the metadata group information and association structure data are expressed using Map), the metadata group information is a collection of metadata information surrounded by topic tags as shown in FIGS. 8 (a) to 8 (c). Thus, the association structure data becomes link information for associating metadata surrounded by association tags shown in FIGS.
[0060]
Next, the metadata editing unit 25a constructs a navigation route for each user by combining the association structure data and the metadata group information and handling it as one piece of knowledge structure data (step S306). As a result, it is possible to implement a relationship 10002 between topics according to the user in the metadata information aggregate 10001 as shown in FIG. 15, and a navigation route 10003 can be realized. Note that the combination of the association structure data and the metadata group information can be realized by DOM (Document Object Model) which is a conventionally known method.
[0061]
(Display information generating means 23a, steps S307 to S308)
The display information generation unit 23a calls a display style sheet from the style sheet DB 231, sets knowledge structure data combining association structure data and metadata group information to the style sheet (step S307), and sets the client terminal's knowledge structure data. The navigation route can be presented to the user by displaying on the browser (step S308).
[0062]
In the above, the example of the process with respect to the user previously registered into the user profile 261 was shown. Next, a process (steps S309 to S311) at the time of new registration of a user will be described using the flowchart of FIG.
[0063]
When the user information management unit 26 obtains from the user that the system is used as a new user, the user information management unit 26 transmits request information for requesting user information to the new user. That is, a style sheet for inputting user information is displayed on the browser 11 on the client terminal 10 through the display information generating means 23a (step S309). Next, the user inputs necessary information as user information and transmits it to the user information management means 26 (step S310). Further, the user information management unit 26 searches and acquires a user profile similar to the user information from the user profile 261, and stores the user profile in the user profile 261 in association with the new user (step S311). The subsequent steps S304 to S308 are the same as described above.
[0064]
(Effect of the second embodiment)
As described above, according to the present embodiment, the communication unit 21, the management unit 22, the display information generation unit 23a, the metadata editing unit 25a, the user information management unit 26, the metadata management unit 31a, By providing the content management means 41, a navigation route for each user can be set, so that the navigation route can be dynamically changed according to history information such as user preferences and purchase history.
[0065]
