2. Description of the Related Art In some cases, a Web page accessed first when a user connects to the Internet is called a portal site.

There is a search engine as a general portal site, which provides a service for searching for information scattered on the Internet by a keyword. Such a portal site collects information scattered on the Internet by, for example, a search robot and forms a database, and when a keyword is supplied from a user, retrieves the corresponding information from the database and provides it.

Conventionally, when information on the Internet is made into a database, HTML (Hyper Text M) is used.
arkup Language)
A method has been used in which a search robot acquires (Uniform Resource Locator) and meta information (keywords and the like) described on the page and stores them in association with each other. When a keyword is supplied from a user, meta information corresponding to the keyword is searched, and the obtained meta information and URL are returned as a search result.

[0005]

In the current portal server, display customization is performed for each user. It is also conceivable that the display content is individualized for each user or group, and only the content that each user is interested in is selected and displayed.

However, in the current portal page, it is necessary to create a mechanism that allows the administrator of the portal site to customize each user. For this purpose, a complicated operation is required, and when the information referred to is increased or changed, it is necessary to perform an operation for following the information.

[0007] The present invention has been made in view of such a point, and an object of the present invention is to provide an information processing apparatus capable of easily editing and processing information managed in a distributed manner.

[0008]

According to the present invention, in order to solve the above-mentioned problems, an information publishing server 1 shown in FIG. In the information processing system including the portal server 3 that generates display data to be provided to the user, the content storage unit 1a included in the information disclosure server 1 stores content including information and services to be provided. The additional information storage unit 1b stores attribute information of each of the contents stored in the content storage unit 1a and additional information including information indicating the relationship between the contents. Further, the additional information acquisition unit 3 a of the portal server 3 acquires additional information from the information disclosure server 1. The additional information storage unit 3b stores the obtained additional information. The editing unit 3e edits the additional information stored in the additional information storage unit 3b according to the administrator's intention or the user's preference. The display data generation unit 3c generates display data for displaying a page from the additional information stored in the additional information storage unit 3b in response to a request from the client 5. The transmitting unit 3d transmits the generated display data to the client 5 that has made the request. Further, the transmission request means 5 of the client 5
“a” makes a transmission request for predetermined display data. The receiving means 5b receives the display data transmitted as a result of the transmission request. The display output unit 5c displays and outputs the display data received by the receiving unit to the display device 6.

As a result, the portal server 3 stores the additional information in which the attribute information of the content held by the information disclosure server 1 and the information indicating the relation between the respective attribute information are associated with each other. In the conventional portal server, the dependency relationship between contents required when generating a page has to be generated by an administrator of the portal server. However, in the present invention, since the additional information includes information indicating the relationship between the contents, a page can be easily generated by using this information.

[0010]

Embodiments of the present invention will be described below. FIG. 1 is a principle diagram for explaining the operation principle of the present invention. Here, the information disclosure server 1 discloses the content to the client 5. Portal server 3
Acquires information related to the content from the information disclosure server 1 and provides it to each client. Client 5
Acquires the display data generated by the portal server 3 and displays it.

The information disclosure server 1 includes a content storage unit 1a and an additional information storage unit 1b. The content storage unit 1a stores content including information or services.

[0012] The additional information storage means 1b stores additional information indicating the attributes of the contents to be published and the mutual relations among the contents stored in the content storage means 1a.

The portal server 3 includes an additional information acquisition unit 3
a, additional information storage means 3b, display data generation means 3c,
It is composed of a transmitting unit 3d and an editing unit 3e.

The additional information obtaining means 3a obtains the additional information stored in the additional information storage means 1b of the information disclosure server 1 according to a predetermined method. The additional information storage unit 3b stores the additional information acquired by the additional information acquisition unit 3a.

When a request is made from a predetermined client, the display data generation means 3c acquires the corresponding additional information from the additional information storage means 3b and generates display data.

The transmitting means 3d includes a display data generating means 3c
Is transmitted to the client that made the request. The editing unit 3e edits a folder in the additional information storage unit 3b, in which the additional information is stored, and a template (details will be described later)
And edit its arguments.

The client 5 includes a transmission requesting unit 5a, a receiving unit 5b, and a display output unit 5c. The transmission request unit 5a requests the portal server 3 to transmit predetermined display data.

The receiving means 5b receives the display data transmitted from the portal server 3 as a result of the request from the transmission requesting means 5a. The display output unit 5c displays and outputs the display data received by the receiving unit 5b.

Next, the operation of the above principle diagram will be described. First, the administrator of the information publishing server 1 stores the content to be disclosed in the content storage unit 1a, and also associates each attribute of the content to be disclosed among the stored contents with the relationship between the contents. As additional information, additional information storage means 1b
To be stored.

The additional information acquisition means 3a of the portal server 3
Accesses the information disclosure server 1 at predetermined intervals and acquires the additional information stored in the additional information storage unit 1b. The additional information storage unit 3b generates folders according to the logical structure of the content, and stores the attribute of the content for each folder.

FIG. 2 is a diagram showing an example of information stored in the additional information storage means 3b of the portal server 3.
In this example, the information obtained from the information disclosure server is stored under the folder “Contents”, and the information necessary to display the information obtained under the folder “Pages” on the client side (display data generation Information to do)
Is stored.

Information acquired from the information disclosure server 1 is stored in a folder “server A” immediately below the folder “content”. In this example, folders A to C in which contents A to C are respectively stored are stored.
Note that such a hierarchical structure is generated from a logical structure of the additional information of the information disclosure server 1.

Under the folder "page", information for customizing the display format and display content when displaying the information stored in the folder "content" on the display device 6 of the client 5 for each user. Is stored. Specifically, the folder “default” stores information on a default state prepared by the portal server 3 side. Under the folder “Group”, customization information for each group is stored. For example, when a user belonging to the group A accesses, a page is generated according to the contents of the folder “Group A”. become. The folder "individual" stores information for customizing display contents for each individual.

Each folder stores attributes related to the content, information for designating a template serving as a template for generating a page from the content, and arguments supplied to the template. The portal server 3 generates a page (display data) by giving an argument to the specified template and executing it.

Incidentally, the administrator or user of the portal server 3 sends the additional information storage means 3 via the editing means 3e.
By editing the folder, template, and argument stored in b, the display form of the page displayed on the client 5 can be changed.

For example, the administrator of the portal server 3 can create a new folder D under the folder C, change the order of the folders, and delete unnecessary folders. Further, it is also possible to refer to another folder from a certain folder by forming a shortcut. Further, by editing not only folders but also templates associated with the folders and arguments stored in the folders, it is possible to change the display contents. For example, by changing the template to be used, the content can be displayed in a list format or displayed in divided frames. Further, by editing the argument, the content of the content to be displayed can be changed.

As for the user's own folder, the display contents can be edited in the same manner as described above. For example, the user "Yamada" can refer to the contents of another folder by creating a new folder under his / her folder "Yamada" or generating a shortcut. Further, the display contents can be changed by editing the template and the arguments.

Such an editing operation can be easily performed by using a GUI (Graphical User Interface) provided by the editing means 3e. With the above processing, the preparation on the portal server 3 side is completed. Then, in such a state, the predetermined user
, The portal server 3 performs an authentication process, and if the user is a valid user, checks whether this user has a personal folder. For example, when the user “Yamada” accesses, it is determined that the corresponding folder exists because the folder “Yamada” exists. If the personal folder does not exist, it is determined whether the group folder exists,
If not, the default folder is determined to be the target folder.

The portal server 3 acquires a template and an argument associated with the corresponding folder, and generates a page. Here, since the content itself is stored on the information disclosure server 1 side, for example, a URL (Uniform Resource Locato
r) is embedded.

The generated page is transmitted to the requesting client 5 via the transmitting means 3d.
In the client 5, the receiving unit 5b receives the transmitted page, acquires the content from the information disclosure server 1 if necessary, supplies the content to the display output unit 5c, and outputs the content to the display device 6.

As described above, according to the information processing system of the present invention, the information disclosure server 1 stores the additional information indicating the attribute and the logical structure of the content, and the portal server 3 stores the additional information. And a corresponding folder is generated, so that the administrator of the portal server or each user can easily edit the page.

In addition, since a template is assigned to each folder and the argument is stored in the folder, the display contents of the page can be easily changed by selecting a template or changing the argument. Becomes possible.

Furthermore, since only the attribute information is acquired and stored, compared to the case where all the information is acquired and stored, it is possible to prevent network congestion and reduce the capacity of the storage device. Becomes possible.

Each version update date and time indicates the update date and time of each version.

(2) Procedure for Registering Information Disclosure Server in Portal Server The portal server 13 accesses a previously registered information disclosure server and collects additional information. Therefore, when a new information disclosure server is added, a registration process is required.

In the registration process, first, it is necessary to create and register an XML document that describes the attribute and logical structure of the content to be disclosed. Here, the use of the XML document is for facilitating creation of additional information because XML is general-purpose. Hereinafter, a method of creating additional information will be described with a specific example.

FIG. 11 shows an example of information that the information disclosure server intends to release. In this example, the folder "Company"
Stores a folder “by district” and content “company-wide profit / loss forecast”. In the folder "By district"
The folder “by company” and the content “expected profit / loss by district” are stored. In the folder "by company", the content "visit record by company" is stored. The information associated with the above information and details of each content will be described below.

1) Sales Data (Information) Numerical data for calculating a company-specific profit or loss forecast or a company-specific profit / loss forecast, and is stored in a database. This information itself is not managed as content information. Therefore, it does not manage the attribute information and the relationship with other information and services.

2) Visit diary (information) This is document data in which a visit history of a customer company is recorded. This information itself is not managed as content information. Therefore, it does not manage the attribute information and the relationship with other information and services.

3) Company-wide profit / loss estimation applet (service) This applet performs OLAP for obtaining the company-wide profit / loss forecast using the sales data of 1) as input, and displays a result form. Information for accessing the target database (database name, etc.) is described in the applet. The attribute information and the related information are as follows.

As shown in this figure, the parent-child relationship of the content is described by the logical structure between the tags of the XML document. Such an XML document is generated by an administrator of the information disclosure server and stored in a predetermined folder of the information disclosure server.

Note that such an XML document may be automatically created by a program or the like. Examples of the method of automatically creating the data include a process shown in FIG. 18 described later and a database TOC (Table of Content).
nts), and can be realized by processing for converting the logical structure into an XML document by referring to the information stored in the XML document.

When the creation and registration of the XML document are completed, a process for registering the information disclosure server in the portal server 13 is executed according to the flowchart shown in FIG.
When this flowchart is started, the following processing is executed. [S1] The server definition information is set. Note that the definition information includes a server name, an agent adapter name, a server function name, a data record format on the server, a user registration dictionary (ontology) name, an agent adapter name, an agent adapter input / output interface, and the like.

[S2] The definition set in step S1 is translated and converted into information (agent system information) understandable by the agent system. [S3] The agent adapter is started. [S4] The agent adapter registers the agent adapter definition information. At this time, it is also checked whether or not the agent adapter name is duplicated.

When the registration is completed, an information collection policy by the agent is set. Since the agent collects additional information based on information (information collection policy) registered in advance, the administrator of the portal server needs to create and register an information collection policy in advance.

The collected information is stored in a designated folder of the portal server. Therefore, by setting a collection policy for this folder, a method of collecting information can be specified.

FIG. 14 shows an example of the information collection policy. In this example, content types, all information collection, and change information collection are shown as setting items. The content type specifies the type of content to be collected. Note that a plurality of contents can be specified. All information collection specifies the date and time when all information is collected. The change information collection specifies the date and time when the change information collection is executed.

The following information is collected as change information. (A) New creation of folder (B) Deletion of folder (including subfolders) (C) New creation of content object (D) Deletion of content object (E) Change of content of content object As described above, information is collected. Once the policy is set,
A condition description XML document as shown in FIG. 15 is generated and supplied to the agent 33. In this example, the tag <statement> and the tag </ statement
The information surrounded by> indicates the acquisition policy. Since this example is an example in which all information is acquired, the acquisition conditions and the like are not set.

(3) Procedure for collecting information from the information disclosure server of the portal server When the definition information of the information disclosure server and the registration of the information collection policy are completed, the agent 33 makes the information disclosure servers 15 to 17 according to the registered contents. Gather information from. 16 to 18 show an example of a process for collecting information from the information disclosure server. First, FIG. 16 is a main flowchart. When this flowchart is started,
The following processing is performed.

[S20] The portal server reads information collection conditions (FIG. 14) from a folder corresponding to the information disclosure server from which information is to be obtained, and generates a condition description XML document (see FIG. 15). [S21] The portal server converts the condition description XML document into
The content is supplied to the agent 33, and a content collection request is made.

[S22] Content collection processing is performed by the agent. The details of this processing are described in FIG.
7 will be described later. [S23] The portal server sends the collected additional information XM
An L document (see FIG. 12) is obtained from the agent 33.

[S24] Convert the additional information XML document to a general-purpose XML
Analysis is performed by an L parser, and a syntax tree as an analysis result is obtained. [S25] It is determined whether or not the collection condition is change information collection. If the change condition is change information collection, step S is performed.
The process proceeds to step S26, and otherwise proceeds to step S29.

[S26] Position the syntax tree in the change information list. That is, the corresponding folder is specified. [S27] The changed additional information is acquired, and the corresponding content object is changed. [S28] It is determined whether or not there is any additional information that has been changed. If there is any additional information, the process returns to step S27; otherwise, the process proceeds to step S33.

[S29] The sub folder is deleted. [S30] Position the syntax tree in the attribute information list. [S31] Acquire additional information to generate a content object. [S32] It is determined whether the additional information still exists. If the additional information exists, the process returns to step S31. Otherwise, the process proceeds to step S33. [S33] It is determined whether or not the folder to be processed still exists. If the folder exists, the process returns to step S20; otherwise, the process ends.

With the above processing, the attribute information XML document is obtained from the predetermined information disclosure server, and in the case of collecting change information, only the content object corresponding to the changed content is changed. In the case of collecting all information, a new content object is generated after all folders are deleted. Here, the content object indicates a folder and attribute information.

Next, details of the content collection processing shown in FIG. 16 will be described with reference to FIG. When this flowchart is started, the following processing is executed. [S40] The agent 33 receives the request from the portal server 13, and transmits the request to the agent adapter to be searched.

[S41] The agent adapter executes a process of generating an additional information XML document. The details of this processing will be described later with reference to FIG. [S42] It is determined whether the additional information XML document generation processing in the agent adapter that has made the request has been completed. If the processing has been completed, the process proceeds to step S43; otherwise, the same processing is repeated. [S43] Merge and sort the collected data in the specified order.

With the above processing, it is possible to acquire the additional information XML document from the agent adapter and merge the data. Next, referring to FIG.
The details of the content collection processing by the agent adapter shown in FIG. This processing is executed by the agent adapter. When this flowchart is started, the following processing is executed. [S50] The agent adapter receives the transmission request from the agent. [S51] The agent adapter determines the collection conditions (FIG. 15).
See).

[S52] The agent adapter writes header information indicating the presence / absence of an error in the additional information XML document which is the output document. [S53] The agent adapter reads the directory settings from the environment setting file describing the environment setting status of the information disclosure server. [S54] The agent adapter moves to the corresponding folder from which the attribute information is to be obtained.

[S55] The agent adapter proceeds to step S56 when acquiring the change information, otherwise proceeds to step S57. [S56] If the modification time of the file to be acquired is later than the reference time to be acquired, the agent adapter proceeds to step S57, otherwise proceeds to step S58.

[S57] The agent adapter writes the contents of the file into the additional information XML document which is the output document. [S58] The agent adapter determines whether or not another file exists in the target folder. If the file exists, the process returns to step S56; otherwise, the process proceeds to step S59.

[S59] The agent adapter determines whether there is any other content to be collected. If so, the process returns to step S54; otherwise, the process proceeds to step S60. [S60] The agent adapter writes a footer for the additional information XML document that is the output document. [S61] The agent adapter returns the created additional information XML document to the agent.

According to the above processing, the agent adapter can collect attribute information from a predetermined folder according to the collection conditions and generate an additional information XML document. According to the processing shown in FIGS. 16 to 18, the agent 33 issues a collection request to each agent adapter according to the collection policy (see FIG. 14), and the agent adapter outputs the additional information XML document in response to the collection request. Generate and reply to agent. As a result, the portal server 13 generates a folder corresponding to the acquired additional information XML document.

To give a specific example, when the information publishing server stores the content as shown in FIG. 11, an additional information XML document as shown in FIG. 12 is generated and transmitted to the agent. Is done. Upon receiving such information, the portal server 13 creates a folder as shown in FIG. 19, for example.

In the example shown in FIG. 19, a folder “content” and a folder “page” exist at the highest level. The folder “content” stores a folder or content (folder object) generated according to the additional information XML document obtained from each information disclosure server. In this example, a folder group corresponding to FIG. 11 is stored in the folder “Server A”.

(5) Access Procedure of Client to Portal Server For example, when a user logs in to the portal server 13 from the client 10, a screen as shown in FIG. 24 is displayed on the display device of the client 10. . On this screen, a window 100 displaying the title “login” is displayed, and in its display area, a text box 100d for inputting a user ID and a text box 100e for inputting a password are displayed. Further, at the lower right of the display area, an OK button 100f operated when logging in with the input content and a cancel button 100g operated when canceling the input content are displayed.

When a user ID and a password are input on such a screen and the OK button 100f is operated, the information is transmitted to the portal server 13.

The portal server 13 performs an authentication process based on the user ID and the password to determine whether the user attempting to log in is a legitimate user. If the user is a legitimate user, the portal server 13 obtains the login name of the user. .

If there is a personal folder corresponding to the login name, the template stored in the folder is acquired and executed. For example, when the user “Yamada” logs in, as shown in FIG.
Since there is a personal folder corresponding to this user,
The template associated with this folder “Yamada” is obtained and executed. As a result, a unique top page generated or edited by the user “Yamada” is displayed. The details of the template execution process will be described later.

On the other hand, if there is no personal folder, it is determined whether there is a folder corresponding to the group to which the logged-in user belongs, and if so, a template associated with that folder is obtained. Executed. As a result, a unique top page edited or generated by the group is displayed on the display device of the logged-in user.

If no group folder exists, the template associated with the default folder (see FIG. 19) is obtained, and the default top page is displayed.

FIG. 25 is a flowchart for realizing the above processing. When this flowchart is started, the following processing is executed. [S70] The portal server 13 acquires a user ID and a password from the client that has logged in.

[S71] The portal server 13 acquires the login name of the user from the acquired user ID and password. [S72] The portal server 13 determines whether or not a personal folder corresponding to the acquired login name exists.
If it exists, the process proceeds to step S73; otherwise, the process proceeds to step S74.

[S73] The portal server 13 acquires a personal template associated with the corresponding folder. [S74] The portal server 13 determines whether or not a folder of the group corresponding to the acquired login name exists. If the folder exists, the process proceeds to step S75; otherwise, the process proceeds to step S76.

As a method of acquiring a group name from a login ID, a method of associating a login ID with a group name is used. [S75] The portal server 13 acquires the template of the group associated with the folder. [S76] The portal server 13 acquires the default template stored in the default folder.

[S77] The portal server 13 executes the acquired template. [S78] The portal server 13 returns the generated page to the client that made the request.

Assume that folders and contents as shown in FIG. 26 are stored under the folder “Yamada” shown in FIG. 19, and when the user “Yamada” logs in, the folder and the contents are stored in the folder “Yamada”. The template that has been acquired is executed. The template executed at this time is a template that assigns contents stored in the subfolder to frames and displays the frames. The template execution process will be described later with a simple example.

FIG. 27 shows an example of a screen displayed on the display device of the user “Yamada” as a result of executing the template. In this display example, “Internet Browses
er "is displayed.
The display area is divided into four frames 110d to 110g.

The name of the logged-in user is displayed in the frame 110d. The table of contents is displayed in the frame 110e, and the selected items are displayed in hot text.

In the frame 110f, an event is displayed, and hot text indicating an event, which is temporary information generated for a specific user, is displayed.

In the frame 110g, a text box for inputting a search keyword is displayed. On such a display screen, if the hot text “2000/4/10 Company-wide profit / loss estimate is confirmed” is selected by the pointer 115, the client 10
Transmits a request corresponding to the hot text to the portal server 13. Here, it is assumed that the information corresponding to the selected hot text is stored in the folder “company” shown in FIG.

When the portal server 13 receives the request, the URL “http: //” corresponding to the folder “company” is received.
/ Server name / contents / server A / company / ". In this case, the template “ap1.tmpl” associated with this folder is acquired and executed.

FIG. 28 shows an example of the template executed at this time. The meaning of this template is as follows. (A) Insert the expression form of the applet object in this folder. (B) At that time, pass the following as arguments.

Content passed in ARG1 URL of own subfolder Here, ARG1 is an argument passed from the client side. In this case, what is passed by ARG1 is an empty string. In the display () method, an expression format specified by the content information is returned. The expression form of the applet object is tag <AP
PRET>, but in this example the object soneki_a, which is a subclass of the applet object
The expression format is redefined by pplet, and the argument Chi
The URL of the folder given by "ld" is used as the value of the parameter "Child". Therefore, a page as shown in FIG. 29 is generated as a result of executing the template.

[0135] The generated page is transmitted to the client 10, where it is executed and displayed.
The applet accesses the sales data and displays the data. When displaying the names of districts such as Tokyo and Osaka, the URL passed by the argument "Child" is used.

FIG. 30 is a display example when the page shown in FIG. 29 is displayed on the display device of the client 10. In this example, a table entitled “Corporate profit / loss forecast” is displayed for frame 110f.

On such a screen, the pointer 115
As a result, if the hot text “Tokyo” in the table is specified, the client 10 adds the argument “Tokyo” to this URL and adds “http: // server name / content /
Server A / company / district? ARG1 = Tokyo ”URL
To access.

Then, the portal server 13 executes a template for the folder “district”. The template specified in the folder is “ap1.tmpl” which is the same as in the case of the whole company. As a result of executing this template as before, a page as shown in FIG. 31 is generated. On this page, the argument name is “Tokyo”, and “Company-specific” is added to the end of the subfolder name.

[0139] Such a page is transmitted to the client 10, and as a result of execution, a screen as shown in FIG. 32 is displayed. In this display example, a table entitled “Tokyo Profit and Loss Estimate” is displayed for frame 110f.

On this screen, when the hot text “Company A” in the table is selected by the pointer 115, the argument “Company A” is added to the ULR of the argument “Child” and “ht” is added.
tp: // server name / contents / server A / company / district / company? ARG1 = Company A ”is accessed.

Then, the folder “by company” is accessed, the same template as in the previous case is executed, and the page shown in FIG. 33 is generated. In the page shown in this figure, “Company A” is designated as the argument “company value”, and the argument “child value”
Is specified as a null string.

Such a page is transmitted to the client 10, where a display process is executed and FIG.
Will be displayed. In this display example,
A table entitled "Company A Visit Record" is displayed for frame 110f.

As described above, according to the information processing system of the present invention, the attribute of the content and the additional information indicating the mutual relation between the content are acquired from the information disclosure server and stored in the portal server. By using the association between the contents when generating the page, compared to when only the attributes of the content are acquired,
A page can be generated more quickly.

Further, according to the present invention, the logical structure of the content is mapped to the hierarchical structure of the folder, so that the content can be easily edited.

In the above embodiment, templates are associated with folders and stored collectively in a predetermined location. However, templates can be stored directly in each folder.

The above processing functions can be realized by a computer. In this case, the processing contents of the functions that the portal server, the client, and the information disclosure server should have are described in a program recorded on a computer-readable recording medium, and by executing this program on a computer, The processing is realized by a computer.
