Abstract

The present invention relates to a method of searching a reference document of a document using a web server.

The reference document search method of a document according to the present invention includes requesting a search for arbitrary document data from a client to a web server, and corresponding to the arbitrary data in a list of reference documents stored by the web server. Extracting the item, and extracting the item and transmitting the extracted item to the client. A reference document for a specific document desired by a user in a general web server without using a conventional information retrieval method through a search engine. Since it can be found by searching the list of documents stored in the web server, there is an effect that can obtain a reference document for a specific document more accurately and quickly than the conventional search engine used.

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for searching a web document, and more particularly, to solve a problem of a method of searching a large database in order to find information desired by a user in a conventional search engine. It is about how to search the reference document.

In general, a search engine such as Yahoo or Alta-vista, which is widely used, is used to search information using the Internet.

When users searched for information with a search engine like this, they found similar words or strings by typing them in the search field.

For example, in the case of a search method using a search engine such as AltaVista, information can be found by moving to a search site to search for a specific website in a document and then entering a specific website as a search string.

As described above, information and document search methods using a search engine which are widely used nowadays often find a desired document by information of the document itself.

These search engines provide information to users by creating or updating a database of information or documents managed by an operator who manages the search engine, or by using a search program that executes the search engine. Providing.

However, the method of searching a web document using such a conventional search engine has the following problems.

First, since there are too many contents of a database managed by a conventional search engine, there is a problem in that it takes a long time to update an existing database with the latest information.                         

Second, since there are too many contents of a database of a conventional search engine, there is a problem in that when a user requests information to be searched, the user cannot quickly respond to the user's request.

Third, since a conventional search engine has a limited capacity database, when a user requests a search for arbitrary information, there is a problem that the search engine does not provide information because there is no information to search in the database that the search engine has. have. SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and does not use a conventional information retrieval method using a search engine, and refers to a specific web document owned by a web server in a general web server. It is to provide a reference document retrieval method of a document using a web server for serving a web site and other retrieval information that contains information about the document to the client.

In order to achieve the above object, a method of searching a document using a web server according to the present invention includes requesting a search for arbitrary document data from a client to a web server, and storing the reference stored in the web server. Extracting an item corresponding to the arbitrary data from a document list, and extracting the item and transmitting the extracted item to the client.

Preferably, the user comprises inputting specific filtering information for the arbitrary document data list in order to find more accurate document data.

In order to implement a web document retrieval method using a system having such a feature, the Hyper Text Transfer Protocol (hereinafter, abbreviated as HTTP) for executing Internet data communication must be changed. The reason for changing the protocol is that communication cannot be performed when the protocols of the respective network communication systems are different.

 For this reason, you need to change the protocol and make the following additions to the client and web server.

First, by adding information field D to GET, which is a transmission option of HTTP, web server and client should be able to process information field D.

Second, we need to add a new transfer option called REFGET to HTTP, which will then be enabled on the web server and client.

Hereinafter, an operation according to a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

FIG. 1A is a view for explaining an operation of a client sending a request for document data stored in a web server in a method of searching a web reference document using a web server according to the present invention.

Referring to Figure 1a, the operation in the case of using the web document search system according to the present invention is as follows.

When the user wants to retrieve a document, the client 10 displays the stored document data A 11 on the screen.

Document data A 11 has a link to document data B 14 stored in the web server 12.

The client 10 sends a request for the document data B 14 to the web server 12 by the user's document data request (S10).

This request is shown in Table 1 below.

GET (URL (dB), D)

In Table 1 above, GET represents the name of a request sent to the web server 12.

In addition, URL (dB) is a value indicating the position of the document data B14.

In addition, D represents the information of the document data A11 sent to the web server 12. As shown in FIG.

The information to be included in the document data A 11 information (document title, document content, document data link information) and client 10 information (client IP address, type of web browser).

The web server 12 receiving the request of the client 10 adds the information entry to the reference document list 13 for the document data B 14 and updates the list (S11).

The fields of the information entries contained in this reference list 13 are shown in Table 2 below.

Information item = (information D sent by client, time when D was sent to server)

Using the information items in Table 2 above, the reference document list 13 of the document data B 14 is updated and stored in the web server 12.

The web server 12 transmits the document data B 14 stored in this way to the client 10 (S12).

FIG. 1B is a diagram illustrating an operation of a client sending a request for a reference document list of document data stored in a web server as shown in FIG. 1A.

Referring to FIG. 1B, the operation in the case of using the web document retrieval system according to the present invention is as follows.

In order to obtain a list of documents referring to the document data B 24 stored in the web server 22, the client 20 allows the user to enter a search option.

When the user inputs a search option, the client 20 requests the reference document list 23 for the document data B 24 from the web server 22 (S20).

Such a request is shown in Table 3 below.

REFGET (URL (dB), O) -REFGET: Request Name-URL (dB): URL of document data B-O: Option sent to web server

Option O indicated in Table 3 above is input by the user and sent to the web server 22 by the client 20.

The web server 22 executes the step of extracting 25 the item corresponding to the option O from the reference document list 23 for the document data B 24 (S21).

The extracted items are converted into a HyperText Mark-up Language (HTML) file, which is a language used to express data on the Internet, by the web server 22.

Accordingly, the web server 22 transmits the item converted into the HTML file format to the client 20 (S22).

Using the document retrieval method referring to the web document according to the present invention as described above has the following effects.

First, a general search engine searches a large database to find a web reference document, but since the web server according to the present invention maintains information on each document data separately, the speed of searching a document is high. .

Second, it can be applied to general web server and client, so that users can quickly find the reference document information about the desired document without using the search engine.

Third, even if the specific document data is not in the search engine's database, the web server can find a document referring to the specific document data.
