Abstract

PROBLEM TO BE SOLVED: To properly process the data on the identification information on the computer resources even in a system where an operation system is not established yet by detecting the identification information on the resources contained in a computer to produce a set of the identification information and executing a prescribed arithmetic operation on this set. SOLUTION: A result working part 145 and a result processing part 147 are prepared, and a URL, i.e., a piece of identification information on the computer resources is cut from the data including the URL to produce a result set. Then a set arithmetic operation is performed to the result set. The part 145 receives the retrieval result from a WWW server interface via a browser interface 143, segments only the URL from the contents data on the retrieval result and transfers the URL to a result management part 146. When the part 147 receives a processing request of the result set from a request analysis part 144, the part 147 requests the part 146 for the result set that is stored in a result storing file group 149 and to be processed and executes the requested processing on the read information.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data processing system for processing data including computer resource identification information collected on the Internet or an intranet, for example. The present invention also relates to a recording medium on which a program for controlling such a data processing system is recorded.

[0002]

2. Description of the Related Art Conventionally, a database management system (hereinafter, referred to as a D)
BMS) is used. The DBMS is: Data storage 2. Search 3. It consists of three functional elements: processing of results. Relational database management system (RDB or RDBM
S) is its representative. The user creates an application by using a search unit or a processing unit on a logical model. As a representative example of this model, the above-mentioned RDB
Network DB (NDB), hierarchical DB
(HDB).

[0003] In recent years, with the spread of the Internet and intranets, there has been provided a method of accessing a DBMS via these networks, but the method of use is the same as in the case of using a normal DBMS.

[0004] On the other hand, apart from the DBMS technology, a search engine has been developed in response to a request to efficiently search for a homepage on which information desired by the user is posted from among the homepages on the Internet which are increasing at an explosive rate. Have been.

[0005] These can be roughly divided into two types according to the method of registering a homepage. One is
This type is represented by yahoo (http://www.yahoo.com),
yahoo has a search hierarchy like the directory structure of the file system. The person who registers the homepage then self-declares where in this hierarchy he wants his or her page to be registered, and the registered information is provided to the searcher.

Another is InfoSeek (http://Japan.Info
This type is represented by Seek.com/), where a robot that regularly patrols the Internet examines the homepage, cuts out keywords and registers them in its own search engine.

[0007] With the development of such search technology, the Internet is permeating society as an information sharing means.
In particular, the intranet, which uses the Internet within an organization, has become an indispensable means of sharing information, mainly among major companies. A great deal of organizational information, such as electronic mail and file sharing, is being accumulated on the intranet, and it has been said that the intranet is a huge database. Of course, the Internet, which stores the latest public information from around the world, is also an important database for organizations. The benefits of using the intranet for a company cannot be measured because the intranet allows seamless access to Internet information (although there are restrictions for security reasons).

Now, in order to utilize a large amount of data without being limited to a database, the above three "data storage", "search", and "result processing" are important.
Organize and store existing data considering the time of use,
It is not limited to databases and computers that can be used for the original purpose, such as quickly accessing when necessary and further processing the same.

[0009] Looking back on the situation of the intranet which has been converted into a database of the organization, it can be seen that "storage of data" and "search" among the three functions are already provided as described above. However, at present, "processing of the result" is not particularly prepared.
For example, if you want to search for homepages related to "airports", the yahoo-type search engine will register the creator of the page, so you can do an accurate search. However, if you do not register the creator of the page, it will not be searchable, so I would like to find it on Infoseek type search engine. Generally, a robot registered in this type of search engine searches characters of a visited homepage, so that an image logo such as “Narita New Tokyo International Airport” is not registered. Therefore, it is necessary to search both types of engines and integrate both results, but at present, humans are obtaining the required results while examining the contents of the search results of each search engine one by one. is there.

The case of performing a search using two types of search engines will be specifically described with reference to FIGS. 26 and 27.

FIG. 26 is a diagram showing a normal search procedure in the WWW.

FIG. 27 is a diagram showing an example of the search result in FIG.

In the examples of FIGS. 26 and 27, it is assumed that two search engines search for a page related to "airport", and a necessary page is found from both results. Such a search is performed by accessing the Internet from the intranet 200 via the gateway 205.

In the example of FIG. 26, first, the search engine 203
The search is performed with. The WWW servers 211, 212,. . . Access and check. At this time, it is general that important pages are recorded using a “bookmark function” which is a kind of a bookmark function provided on the WWW browser on the client 204.

Next, the same processing is performed on the results searched by the search engine 213, and the necessary results can be obtained by collecting the finally recorded pages (URLs). In this process, there is generally an overlap between the result of the search engine 203 and the result of the search engine 213. This is shown in FIG. FIG.
Http://www.xx.co.jp/a.html is duplicated. Such duplicated search results often result in the same page being accessed many times. Note that the URL is page identification information of the Internet (or intranet), but is a kind of identification information of resources in a computer as well as identification information of a process, data, a printer, a keyboard, or the like.

On the other hand, DBMS such as RDBMS
Provides a (conceptual) form of data and an operating system for it. As described above, since all data is described based on the model, it is easy to realize various efficient searches and operations in the sense that the method of implementing the operation system in the data format is determined. It is.

[0017]

On the other hand, in the world of the Internet / intranet, the homepage is HTML.
Although a description format of (Hyper Text Markup Language) has been determined, there is no agreement on the operation system, and integration or comparison between search results has not been realized as described in the above example. Therefore,
In the case described above, for example, there was no other way but to check the search results by the InfoSeek type search engine or the yahoo type search engine at a glance.

The present invention has been made in view of such circumstances, and even in a system in which an operation system has not been established, it is possible to appropriately perform data processing on the identification information of the computer resources. It is an object to provide a data processing system. Another object of the present invention is to provide a recording medium on which a program for controlling such a data processing system is recorded.

[0019]

The gist of the present invention is a data processing means for cutting out identification information from data including identification information to create a set, and executing a predetermined arithmetic processing for two or more sets. The processing unit and the computer function to construct a data processing system on the computer. The feature of the present invention resides in that the identification information is identification information on resources in the computer such as data, a computer process, or the computer itself.

By providing such a function to a computer, even in a system in which an operation system has not been established, it is possible to take out only identification information such as computer resources and form a set. The set can be subjected to an operation process such as a set operation. Furthermore, since the set subjected to the operation is the identification information of the computer resource, the subsequent access to the computer and the like can be made efficient by an appropriate operation processing result.

According to a first aspect of the present invention, to achieve the above object, the identification information is found from data including identification information on resources in a computer, and the found identification information is found. And a processing means for executing a predetermined operation on the set of identification information created by the data processing means.

According to the second aspect of the present invention, there is provided a data processing means for cutting out identification information from data including identification information on resources in a computer such as a computer process or a computer itself to create a set, A computer-readable recording medium that records a program for causing a computer to function as a processing unit that executes a predetermined arithmetic process on two or more sets.

According to the present invention, a set of useful identification information can be obtained based on the result of searching the network. Therefore, the set can always be updated by searching or the like, and a timely set of identification information can be obtained.

Furthermore, the present invention provides a method for identifying information or UR
It is assumed that data including L can be obtained by different data search means.

Thus, for example, in a data processing process, when a union set or a common set is obtained, a set of identification information utilizing the properties of the different data search means can be obtained.

[0026]

Embodiments of the present invention will be described below. (First Embodiment of the Invention) FIG. 1 is an overall configuration diagram showing an example of an intranet / Internet having a data processing system realized by a recording medium according to a first embodiment of the present invention.

As shown in FIG.
Are connected to the WWW server 111, the WWW server 112, the search engine 113, and the intranet 100.

The intranet 100 forms, for example, an intra-company LAN system, and includes a WWW server 1
01, WWW server 102, search engine 103, client system 104 (hereinafter simply referred to as client
4) and a gateway 105 (G / W) are connected to the data transmission path 100a.

The WWW servers 101 and 102 are departmental servers on the intranet 100, and are used as information sharing means. The WWW server 101 is used for sharing a document in a normal WWW server. On the other hand, the WWW server 102 is a server for accessing the DBMS 106. Members of this organization proceed with work while accessing necessary information using a client 104 such as a personal computer. At this time, it is possible to perform a keyword search or a search based on classification using the in-house search engine 103 as necessary. In addition, WWW
Server 101, WWW server 102, search engine 10
3 are often started up in each section, and although not particularly shown in FIG. 1, usually there are a plurality of these.

The client system 104 has WWW
A browser (not shown) and a result collection unit 131 are provided.

Here, since the intranet 100 is connected to the Internet 110 via the gateway 105, the WWW browser can also access the WWW servers 111 and 112 published on the Internet 110 via the gateway 105. It is. A DBMS 114 is connected to the WWW server 112. Further, as in the case of the company, it is also possible to perform a search based on a keyword search or a classification using the search engine 113 on the Internet.

On the other hand, the result set processing unit 131 is connected to the search engines 103 and 113 via the client 104. The relationship between the three functions for storing, searching, and processing a large amount of data by the computer described in the related art and the components in FIG. 1 is as follows.

1. Data storage: WWW server 101,
102, 111, 112 2. 2. Search: WWW servers 102 and 112, search engines 103 and 113 Result Processing: Result Set Processing Unit 131 Hereinafter, a method of implementing the result set processing unit 131 and its configuration will be specifically described.

FIG. 2 is a diagram showing an example of a method of implementing the result set processing unit.

FIG. 5 shows a method of realizing the function of the result set processing unit 131 by an active X program using a WWW browser in the client system 104. Active X program is user WW
A WWW server accessible from a W browser (for example, W
The WWW is stored in the storage device 101a of the WWW server 101).
Stored as a server page. U on this page
It is assumed that the RL is open (users know).
When using the functions of the present invention, the user must first
The active X program 404 is called by designating the RL. This feature can then be used with a "built-in" image on the user's WWW browser. As a method of realizing the result set processing unit 131, there are also a method using a Java applet as described later and a method using a CGI or the like on the WWW server side. UR
L is identification information for the page, and is one of the identification information of the computer resources.

FIG. 3 is a block diagram showing a configuration example of a result set processing unit which is a main part of the data processing system according to this embodiment. Here, a configuration in the case of the above-described active X program realizing method is shown.

Referring to FIG. 3, the result set processing unit 131 is composed of hardware of the client system 104 and an active X program and data for controlling the hardware, and includes a processing unit 141 and a result holding unit 142.

The processing section 141 receives a request from the WWW browser 132, and makes a request to the WWW browser 132. The browser interface 143, the request analysis section 144, the result processing section 145, the result management section 146, and the result processing section 147. It is composed of

On the other hand, the result holding unit 142 is provided with a result set table 148 and a result storage file group 149. When the result holding unit 142 is provided in the main memory of the client system 104, it forms a part of the active X program and its data. However, when provided in a secondary storage device such as a hard disk, for example, the result holding unit 142 is configured in separate hardware, although under control of a program as a program on the main storage.

Next, the configuration of each unit of the result set processing unit 131 will be specifically described.

First, the browser interface 143
Receives a search request from the user via the WWW browser 132 and passes it to the request analysis unit 145. If there is a search / read request from the request analysis unit 145 to the WWW server, the request is passed to the WWW server interface of the WWW browser 132 (not shown). The browser interface 143 receives, from the WWW browser 132, the result of the WWW server interface sending the request to the LAN according to the http protocol and returns the result to the browser 132 to display the result to the user. At the same time, the result is sent to the result processing unit 145.

Further, the browser interface 143
Is the data managed by the result management unit 146 or the result processing unit 1
In order to display the data processing results by the user 47 to the user, these are sent to the WWW browser 132.

The request analysis unit 144 determines whether the request input from the browser 132 is a search / read request to the WWW server or a result set processing request. Here, in the case of a search / read request to the WWW server, the request is passed to the WWW server interface via the browser interface 143. On the other hand, if it is a result set processing request, the request is delivered to the result processing unit 147 or the result management unit 146.

Upon receiving the search result from the WWW server interface via the browser interface 143, the result processing unit 145 cuts out only the URL from the content data of the search result, and stores the cut out result in the result management unit 1.
Deliver to 46.

The result management unit 146 stores a set of URLs as a result set received from the result processing unit 145 in any file of the result storage file group 149 in the result holding unit 142. At this time, the management information is recorded in the result set management table 148. Note that the result management unit 1
46 sends the storage status of the result to the browser interface 143 for display on the browser 132.
Also, the result storage file group 149 is sent from the request analysis unit 144.
When a request for deletion is received, the request is executed.

When the result processing unit 147 receives a result set processing request from the request analysis unit 144, the result processing unit 147 requests the result management unit 146 to process the result set stored in the result storage file group 149. Perform the requested processing on the read information. Further, the processing result is
The result is sent to the browser interface 143 for display by the W browser 132, and the result management unit 146 is sent.
To be stored in the result holding unit 142.

Next, the operation of the data processing system realized by the recording medium according to the embodiment of the present invention configured as described above will be described.

First, the overall operation will be described with reference to FIG.

FIG. 4 is a diagram showing an operation example of this embodiment.

In the figure, the result set processing unit 131 saves the search results of the user and performs processing between the saved results. First, the user sets search conditions in the client system 1 in the same manner as when performing a normal search.
04, a request is issued to the search engines 103 and 113 by the operation of the request analysis unit 144 and the WWW browser 132, and the result is obtained. In the result set processing unit 131, only the URL is taken out by the result processing unit 145 in the result set processing unit 131 and held as a URL set (result set).

Using search engines 103 and 113,
Assuming that the search has been performed twice, both of the results are held as a set of URLs in the result set processing unit 131, so that the user only needs to perform necessary operations between these sets.

For example, suppose that the user wants to search for the latest page in the page relating to “airport”. For the yahoo type search engine, the homepage creator informs the search engine administrator of "What category of page do you want to register?", and if the search engine administrator does not register according to the request, Not be. Therefore, it is assumed that this type of search engine takes a long time after the homepage is created until it can be searched. on the other hand,
In the InfoSeek type search engine, the robot crawls on the Internet, and when it finds a new page, it automatically registers it in the engine, so it may not be possible to obtain complete search information. Therefore, after searching for a page related to “Airport”, a search is performed with a yahoo type search engine, and then the result set processing unit 131 performs a union operation, so that search results with no overlap and high completeness can be easily obtained. can get.

Next, the operation of each unit of the result set processing unit will be specifically described with reference to FIGS.

First, with regard to the processing of the request analyzer 144, it is determined whether the request is a search / read request to the WWW server or a result set processing request as follows. The input from the user is input via an active X program running on the WWW browser 132. Therefore, if a specific symbol for identification is inserted into the input of the processing request for the result set, this can be easily recognized. Requests to the WWW server are not limited to URL search. Therefore, in this case, an unnecessary URL set is created. However, practical problems such as “the user clears the result as appropriate” and “the result processing means processes only the result from the search engine” are not practical problems. Not particularly.

Next, the processing of the result processing section will be described.

FIG. 5 is a flowchart showing the processing of the result processing section.

This process is for extracting a URL from a search result.

First, the output file is cleared (ST
1). Next, the search result file is read (ST
2). Then, a certain reference URL included in the search result
Everything is cut out (ST3).

The certain reference in step ST3 is as follows in the present embodiment. That is, H
In TML, the link to the page is <AHREF = "http: // www.
xx.co.jp/a.html">xxxx </A> etc.
A set of URLs is obtained by using the criterion of cutting out the next ">" from EF = "".

FIG. 6 is a diagram showing a configuration example of the result set management table.

In this example, there are n result storage files. In the figure, the result storage file indicated by the table elements from SP to EP is the currently effective result set. These result storage files may be provided in any of the main storage (memory) and the secondary storage device (hard disk or the like) as described above.

The result of the search is stored in the E by the result management unit 146.
The result is stored in the result storage file stored in the table element indicated by P. After storing the result, the EP is increased by one (if EP is N, EP = 1). The result set is cleared by the request analysis unit 144 analyzing a “result clear” command or the like from the user and giving a clear instruction to the result management unit 146 based on the analysis result. In this case, SP = EP = 1.

FIG. 7 is a flowchart showing an outline of the processing of the result management unit.

To the result management unit 146, three processing requests of “clear result”, “add result”, and “process result” are input, and processing corresponding to the request type is executed (ST11). ).

First, when the result is cleared (ST12),
A request from the user is transmitted via the request analysis unit 144. In this case, as described above, all the result storage files are cleared (ST121), and SP = EP = 1 processing is performed (ST122).

In the case of adding a result (ST13), the result to be stored is sent from the result processing unit 145 or the result processing unit 147. In this case, a new result is stored in the result storage file (ST131), and the result management table is updated (ST132).

In the case of the result processing (ST14), since the result processing unit 147 sends a command / content for reading and writing the result storage file, the contents of the specified result storage file are returned (ST141).

Any of the processes (ST12, ST13, ST
After 14), the status of the post-processing management is sent to the browser interface 143 and displayed to the user from the WWW browser 132 (ST15).

FIG. 8 is a flowchart showing an outline of the processing of the result processing section.

FIG. 11 shows processing for two result sets, but processing can be similarly performed for a plurality of processing.

First, let A be one of the operation result sets,
Let B be another one of the operation result sets. Further, the designated arithmetic processing is set to R, and X for storing the result is cleared (ST21).

Next, the result sets A and B to be operated are called from the result management unit 146 (ST22), the ARB operation is executed, and the result is stored in X (ST23).

Then, the result is displayed to the user via the browser interface, and the result management means is requested to register the result (ST24). Thereby, the user can use his / her own processing result in the same manner as the search result.

FIG. 9 is a flowchart showing an example of processing of a common set of sets A and B by the result processing unit.

First, the set X in which the result is stored is made an empty set (ST31), and the processing of step ST321 is performed for each URL (element a) in the set A (ST32).

In the process of step ST321, it is first determined whether a = b for each URL (element b) in the set B (ST3211). a
= B, the same processing is performed for the next element b (S
T3214), if a = b, a is added to the set X (ST3212), and the process exits this loop (ST321) (ST3213).

Thus, the common UR of the set A and the set B
A common set X consisting of L is generated. For example, a case will be described in which the above-described processing is executed from the set of FIG. 26 illustrated in the related art. Let the result of the search engine 203 be a result set A,
Assuming that the result of the search engine 213 is the result set B, the element “http://www.x.co.jp/
a.html "is obtained.

Next, the case where the union processing is executed by the result processing unit will be described.

FIG. 10 is a flowchart showing an example of processing of the union of sets A and B by the result processing unit.

First, one set A is stored in the set X in which the result is stored (ST41), and the set X in the other set B is stored.
Step ST421 for each RL (element b)
To ST424 are performed (ST42).

In the processing in step ST42, first, a flag (flag) is set to true (ST42).
1) Further, the processing of steps ST4221 to ST4224 is executed for each URL (element a) in set A (ST422).

In step ST4221, it is determined whether a = b. If not a = b, a loop is executed and the same processing is performed for the next element b (ST4224).
= B, the flag is set to false (ST4).
22), exit this loop (ST422) (ST42)
23).

After execution of step ST422, the flag is determined to be true or false (ST423). If true, that is, if element b of set B is not equal to any of element a of set A, element b X (ST4
24).

Thus, the sum of the set A and the set B
A common set X consisting of RLs is generated. For example, a case will be described in which the above-described processing is executed from the set of FIG. 26 illustrated in the related art. If the result of the search engine 203 is a result set A and the result of the search engine 213 is a result set B,
The set shown in FIG. 4 is obtained as a calculation result by the processing of the result processing unit 147.

Although the basic functions of this embodiment can be realized as described above, in this embodiment, means for using a hash function in a processing operation is provided in order to speed up the processing of the result processing unit 147.

FIG. 11 is a diagram showing an example of a hash table used for speeding up the result processing section.

In the figure, the element http://www.aaa.co.jp/a/
Assuming that the hash value of b.html is y, a hash table is created. In this case, this element is stored at the y-th position in the hash table. As an example of the hash function shown in the figure, if the quotient of "aaa.co.jp/a/b" is hashed, the characteristics of the URL can be well represented on the hash table.

FIG. 12 is a flowchart showing an example of processing when the union of sets A and B is obtained by the result processing unit using the above hash function.

First, one set A of the set X in which the result is stored is stored, and a hash table HT of the set A is created (ST51). Next, the UR in the other set B
Steps ST521 to ST521 for each of L (element b)
The process of ST524 is performed (ST52).

In the processing in step ST52, first, a hash value is calculated for element b (ST52).
1).

Next, it is confirmed whether or not the y-th element x of the hash table HT has x = b (ST522). If it exists, the element b is added to the set X (ST523). If not, the loop is executed and the processing for the next element b is performed (ST52).
4).

Thus, the set X is obtained. The hash table is stored in the result processing unit 1 at the time of registering the result.
45 or the result management unit 146, and may be stored in the result holding unit 142 and used at the time of processing.

As described above, the data processing system realized by the recording medium according to the embodiment of the present invention is provided with the result processing unit 145 and the result processing unit 147, and the URL which is one of the identification information of the computer resources. UR from data containing
Since L can be cut out to create a result set and further set operations can be performed on it, systems such as the Internet and intranets that have not established an operation system for data processing of result data by a search engine or the like. However, it is possible to appropriately perform data processing on the identification information of the computer resource.

That is, a search result of a homepage or a file from the Internet / intranet is regarded as a set of URLs, and the processing of the result can be realized by providing operations such as sum, difference, and common. As a result, the Internet / intranet, which is a huge database,
"Result processing" can be automated by a computer, and the sum or intersection of search results from a plurality of search engines can be obtained mechanically. (Second Embodiment of the Invention) In the first embodiment, the case where the data processing system realized by the recording medium according to the present invention is provided on the client system side by using an active X program has been described. However, the present invention can be realized by dividing and arranging each function on the client system side and the WWW server side, or by realizing all functions on the WWW server side. In the present embodiment, J
A case in which each function is divided and arranged on the client system side and the WWW server side to realize a data processing system using an ava applet will be described.

FIG. 13 shows a data processing system realized by a recording medium according to the second embodiment of the present invention in WWW.
FIG. 2 is a block diagram showing a main configuration on an intranet when provided on a server side, and the same parts as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted; Parts not particularly shown in the figure are configured in the same manner as FIG.

In the data processing system of the present embodiment, the part corresponding to the result set processing unit 131 of the first embodiment is the same as the result set processing unit 151 of the client system 104 and the result set processing unit 151 of the WWW server system 101 '. It is divided into a result set processing unit 152 and the result set processing unit 152. In the first embodiment, the WWW server 1
01 and the like mean that a WWW server process operates in a server system as hardware such as a workstation. However, the WWW server system 101 'referred to here has C language (C
++) and a WWW server process 153.

The client-side result set processing unit 151
The Java applet is called and configured on the client system 104. This applet is called by the program 4 of the active X in FIG.
04 as well as the WWW server process 153

Here, the transmitting / receiving unit 156 is for communicating with the client side result set processing unit, and
The access unit 157 responds to a command from the request analysis unit 144,
It is for making a search request to a search engine or the like provided in another WWW server or the like.

Next, the operation of the data processing system realized by the recording medium according to the embodiment of the present invention configured as described above will be described.

First, the overall processing flow will be described with reference to FIG.

First, in the client system 104, a request such as a search or a result process from a user is input to the client-side result set processing unit 151 (a1). The request is added with client identification information by the client side result set processing unit 151, and is transmitted to the server side result set processing unit 152 (a2).

The server-side result set processing section 152 interprets the received request and, in the case of a search request, issues a search request to a search engine or the like (a3). On the other hand, if the request from the server-side result set processing unit 152 is a result process or the like, these processes are executed.

The search result from the search engine is notified to the server-side result set processing unit 152 (b1), and after predetermined processing is executed in the server-side result set processing unit 152, the result is sent to the client-side result set processing unit 151. Sent (b

The result transmitted to the client-side result set processing unit 151 is displayed on the WWW browser 132 and provided to the user (b3).

Next, the operation of the result set processing unit on the client side will be specifically described with reference to FIG.

First, a request from the user is input to the browser interface 143 via the WWW browser 132 (c1). This request is transferred from the browser interface 143 to the transmission / reception unit 154 together with the client identification information (c2) obtained from the user information addition unit 155 (c3), and transmitted to the server-side result set processing unit 152 (c4).

The response (d1) from the server side result set processing unit 152 to this request is transmitted from the transmission / reception unit 154 to the path (d
It is displayed to the user via 2, d3).

Next, the operation of the server side result set processing unit will be specifically described with reference to FIG.

In the server-side result set processing unit 152, search processing, result set clearing, and result set processing are executed in response to a request from the client-side result set processing unit 151.

The specific processing is the same as that shown in FIG. In this process, the request analysis unit 14
4. Each part of the result processing unit 145, the result management unit 146, and the result processing unit 156 operates in the same manner as in the first embodiment. However, the server-side result set processing unit 15 of the present embodiment
In No. 2, a transmitting / receiving unit 156 and a WWW access unit 157 are provided instead of the browser interface 143, so that the processing procedure is as follows.

That is, in FIG. 15, in the case of the search processing, each processing proceeds in the order of e1 to e9. After branching at e6, the process proceeds in parallel. In the case of the result set clear, each process proceeds in the order of f1 to f7. Further, in the case of a result set process, each process proceeds in the order of g1 to g11. The processing proceeds in parallel after g8 and g10.

Thus, processing similar to that of the first embodiment is realized.

As described above, in the data processing system realized by the recording medium according to the embodiment of the present invention, means corresponding to the result set processing unit 131 of the first embodiment is called by the client system. Since it is configured as a Java applet and a process on the WWW server side, the same effects as in the first embodiment can be obtained even when Java is used. In the case of the present embodiment, since the processing on the client side is small, the load on the client system 104 can be reduced.

In this embodiment, the function of the result set processing unit is divided between the client system side and the WWW server side using the Java applet. However, the present invention is not limited to such a case. Not even,
All the functions of the result set processing unit may be provided on the WWW server side. For example, this is called CGI (Common Gateway Interfa
ce). In this case, various requests are realized as requests from the WWW browser to the WWW server.

The present invention is not limited to the above embodiments, but can be variously modified without departing from the gist thereof.

In this embodiment, a case has been described in which identification information, which is a URL code described in HTML, is cut out. However, as described above, the identification information is not limited to the URL code.

For example, XML (eXtensible Markup La
nguage) can be used as identification information. In this XML, it is possible to define and use tags according to the description contents. For example, a description such as <company> Toshiba </ company><address> Minato-ku, Tokyo </ address> indicates that the data relates to a company and its location.

FIG. 16 is a diagram showing a screen of a home page described in XML. FIG. 17 is a diagram showing an XML document of the homepage shown in FIG.

As shown in FIG. 17, <company> Toshiba </ company>, <address> Minato-ku, Tokyo </
Since "address>" is described, it is possible to recognize the company that has opened this homepage and its address.

When a document described in XML is applied to the present invention, the operation target can be "necessary matter itself" instead of "page indicated by URL".
Thus, for example, when the necessary matters are set as the schedules of the respective users, the “schedulable schedule for the user A”
And a set of "A convenient schedule for User B"
A convenient schedule for both parties can be determined.

FIG. 18 is a diagram showing a screen of a home page showing the schedule of the user A, and FIG.
3 is a diagram showing an XML document of a homepage shown in FIG. FIG. 20 is a diagram showing a screen of a home page showing the schedule of the user B, and FIG. 21 is a diagram showing an XML document of the home page shown in FIG.

When finding a convenient schedule between the user A and the user B, as shown in FIG. 22, the XM shown in FIG.
A set A of information indicated by the <schedule> tag of the L document;
A set B of information indicated by the <schedule> tag of the XML document shown in FIG. 21 is created, and a common set (intersection) C, which is a convenient schedule, is obtained from the set A and the set B. As a result, a convenient schedule can be obtained for both the user A and the user B.

In addition to the URL and XML, an appropriate identifier (I
D). Here, the directory service manages the system configuration of a certain organization. When a keyword is specified, a corresponding system component (for example,
Printer, computer).

FIG. 23 is a diagram for explaining a situation where the present invention is implemented together with a directory service. In addition,
1 will be described with the same reference numerals.

As shown in FIG.
Is connected to the client system 104 having the result set processing unit 104 and the DS server 301. D
The S server 301 has a DS server database 302.

In addition, the G / W
The LAN 305 is connected via the G / W 10
The LAN 306 is connected via the LAN 5b. LA above
Elements to be subjected to a directory service, such as a printer and a computer, are connected to the N 305 and the LAN 306, respectively.

These elements correspond to the DS as shown in FIG.
It is managed by a table in the server database 302.

For example, when the "printer" at the location "Tokyo" is searched as a keyword from the client system 104, the DS server 301 searches the DS server database 302 and finds the "host name" and "IP Data such as “address” is returned to the client system 104.

Next, a search is made from the client system 104 using “terminal” at the location “Osaka” as a keyword to obtain “host name” and “set of IP addresses”.

The result set processing unit 131 in the client system 104 executes a predetermined operation based on the data such as “host name” and “IP address” returned from the DS server 301, and as a result, for example, It is possible to simultaneously output or display information on printers and terminals in Osaka.

Furthermore, the present invention can be applied to a domain name service (DNS). The domain name service is for managing network configuration information (network address) of a certain organization.

In this case, the DNS service table of the DNS server is as shown in FIG. 25, for example. As shown in the figure, the difference from the table of the DS server database is that the item indicating the “type” of the component is “domain name” and the item indicating “IP address” is “network address”. It is in.

In the case of the DNS service, for example, when a domain name is retrieved from a client system using a keyword, a network address corresponding to the domain name is returned from the domain network server.

The result set processing unit 131 in the client system, as in the case of the directory service,
A predetermined operation is executed based on the data such as the network address that has been returned.

By replacing an identifier such as a URL or ID with a common identifier, it is possible to perform an operation between a search result from a search engine and a search result from DS (or DNS). For example, it is conceivable to replace all search results with the serial number of the computer or to replace the search result with the name of an organization having the resource.

The method described in the embodiment may be implemented as a program (software) that can be executed by a computer (computer), for example, a magnetic disk (floppy disk, hard disk, etc.), an optical disk (CD, etc.).
-ROM, DVD, etc.), a storage medium such as a semiconductor memory, and the like, and can also be transmitted and distributed via a communication medium. The program stored on the medium side includes a setting program for causing the computer to execute software means (including not only an execution program but also a table and a data structure) to be executed in the computer. A computer that realizes the present apparatus reads a program recorded in a storage medium, and in some cases, constructs software means by using a setting program, and executes the above-described processing by controlling the operation of the software means.
