1 is a block diagram of an Internet search system including a web filtration system according to an embodiment of the present invention.

The user is connected to the internet communication system through the web browser 120 in the user system 110 area. The initial search information (linking address and document of the site, 120) extracted by the web server 130 is processed into information corresponding to the user's satisfaction by the web filtration system 112 (where processing is a change in the information itself). Instead of the initial search information, the information set is converted through evaluation to approach the user's request.

2 is a block diagram of a web filtration system according to an embodiment of the present invention, wherein the web filtration system includes a search request analyzer 200, a filter 230, a search document analyzer 210, and a search document converter 220. It is made to include.

The search request analyzer 200 performs a function of analyzing what the search request contents are so that the contents of the search keyword inputted by the user can be approached to the demand of the user when providing the search results later.

In addition, the search document analyzer 210 performs a function of analyzing the searched document for adjustment according to the user's demand.

In addition, the search document converter 220 performs a function of processing the actual application content in the document selected to meet the needs of the user again from the searched document.

In addition, the filter 230 performs a function of selecting documents close to the user's request from the searched documents based on the analyzed search request information.

In addition, the communication service system includes various search tools which are generally used as an internet communication base, and may be mounted inside or outside the web filtration system.

That is, the filter 230 receives and stores the search request information analyzed by the search request analyzer 200 and then applies the analyzed request information to initial searched documents received from the search document analyzer 210. In order to prepare a document, the necessary documents are extracted and transmitted to the search document converter 220.

3 is a flowchart illustrating an operation procedure of the web filtration system according to an embodiment of the present invention.

First, in step S301, when a search request message by the user is received, it is determined in step S302 whether to operate the web filtration system. On the other hand, the search request message is mainly composed of keywords, it may consist of the necessary search constraints and the required addresses.

As a result of the determination in step S302, if it is not necessary to operate the web filtration system, that is, if a regular search method is to be used without using a filter as a search route, in step S303, a search document is immediately extracted, In step S304, after inserting the connection mark into the extracted documents, in step S305, it transmits to a web browser.

As a result of the determination in step S302, if it is necessary to operate the web filtration system, the search address is extracted in step S306, the search keyword is extracted in step S307, and then the required search constraints are extracted in step S308.

Next, in step S309, the document according to the search address is extracted, and in step S310, the search space is optimized, and in step S311, time and search space are calculated. At this time, the optimization of the search space is based on the search time, the navigation range on the Internet, and the amount of search documents, and the search is evaluated.

As a result of the determination in step S312, if the proper level is not reached, the session is terminated and the search constraint is changed.

As a result of the determination in step S312, if it is an appropriate level, in step S313, necessary documents are selected using a search keyword and constraint conditions, and in step S314, after inserting a linkage indication into the selected result documents, step S315 to step S315; In step S317, the case where a keyword matches the address searched for connection priority determination is determined as the highest priority, and then, whether or not keyword matching is performed in a paragraph unit, priority is placed for each retrieved document. . Then, if the priority is determined, in step S318, the arrangement result is sent to the browser.

Herein, the processing of the connection indication is as follows.

Read a string from the stream while the search stream continues. If the read string corresponds to a concatenated indication, the search address is extracted according to the type, converted to an absolute address, and inserted into the concatenated list. It checks whether it matches and scores the link.

If the type of link indication is another, extract the source address, convert it to an absolute address, and insert the string into a temporary buffer. Also, if the connection indicator is a tag for phrase search, it checks if the temporary buffer matches, and if it matches, sends it to the browser, otherwise releases the buffer. If the connection mark is text, it inserts it into a temporary buffer.

Next, in the connection method of each connection node, nodes are visited while all the visits are not completed. If the node has a link, a new link extracted from the visited site is inserted into the link list and sorted. . By selecting the first link from this sorted list of links, the search results are prioritized.

In addition, the web filtration system according to an embodiment of the present invention is a proxy server (Proxy Server) to switch between various search tools that are generally used on the Internet, that is, another search in one search tool for the continuous progress of the search It has a user interface that does not require a conversion to a tool, and provides a filtering service that extracts only valuable information from documents retrieved in a browser, and processes it into more necessary information.

The present invention as described above is recorded on a computer-readable recording medium, and can be processed by a computer.

As described in detail above, the present invention provides a web filtering system using a prioritization method considering a user's interest in search information and an estimation mechanism for reducing the size of a search space, and a method of operating the same. It has the effect of extracting only valuable information from documents retrieved in a browser with a user interface that does not require a switch between search tools, that is, to continue the search, from one search tool to another.

The technical spirit of the present invention has been described above with reference to the accompanying drawings, but this is by way of example only and not by way of limitation to the present invention. In addition, it is obvious that any person skilled in the art may make various modifications and imitations without departing from the scope of the technical idea of the present invention.
