Next, the operation of the website evaluation system according to an embodiment of the present invention will be described based on this structure.

2 is a flow chart of a website evaluation method according to an embodiment of the present invention.

In order to find the data corresponding to the subject that the information search user, that is, the client 3 wants to know, a program (for example, a web browser) for network connection is run and the evaluation system 1 according to an embodiment of the present invention is executed. If a URL for connecting is entered, this URL information is converted and packetized by HTTP (hypertext transfer protocol) in a web browser and then transmitted to the evaluation system 1 via the network 2.

Accordingly, the interface server 11 of the evaluation system 1 transmits the web page corresponding to the URL information to the client 3, and the transmitted web page is converted into a window state on the web browser and displayed (S100).

When the input window is displayed on the web browser and the search word corresponding to the topic that the client 3 wants to know is input (S110 to S120), the website extractor 121 may include the search word according to a conventional keyword search method. Extract a plurality of websites that provide (S130).

Next, the hyperlink extracting unit 122 extracts hyperlink information included in each website for each extracted website (S140).

In general, a hyperlink serves as a pointer to a website that is correlated with the content of the text, and contains elements such as words, phrases, symbols, and images within a hypertext document and other elements within the document. Represents a link between an element or another element in another hypertext document.

When a user clicks an underlined element in a hypertext document or an element (linked element) that is colored differently from the rest of the document, the hyperlink is activated and linked to another web document. This allows you to select and search for connections between one element and another within the same hypertext document, or to select and search for connections between other elements within a hypertext document on a server on another Internet host hundreds or thousands of kilometers away. have.

In an embodiment of the present invention, a website frequently referred to from related fields may be regarded as a useful website in a particular subject field, as a research paper with a high citation of articles is recognized as an important article. Based on the presence of the web site, it is extracted and the frequency of which web sites are most hyperlinked by other web sites is searched.

The hyperlink extracting unit 122 extracts information hyperlinked by a different website for each website, and stores the information in the link information database 13. At this time, hyperlink information is extracted with a search depth of about one page for each website. That is, for example, the hyperlink information is extracted only from the main page of each website, and the hyperlink information of the sub page is not extracted. However, the search depth according to the present invention is not limited to this, and hyperlink information can be extracted from one or more pages as necessary.

After extracting the hyperlinks for all the websites to be evaluated in this manner, the statistical processor 123 calculates how many websites each hyperlink extracted for each website is based on the information stored in the link information database 131. It is calculated whether the reference from the (S150).

For example, suppose that about 30 websites have been extracted for evaluation based on the search term 'P2P' entered by the user. As a result of analyzing the hyperlink information on the 30 websites, the statistics that the hyperlink named "OpenP2P" was referred to from 29 of the 30 websites were referred to from the most websites.

Next, the ranking unit 124 determines the ranking of the websites in the order that is most frequently referenced based on the hyperlink analysis result (S160). Using the example above, a website named "OpenP2P" is ranked first.

When the ranking is made, the display unit 125 displays the recommended website results so that the information retrieval user is easy to see according to the determined ranking (S170). That is, by displaying the websites by ranking, the user can know that the website displayed above is the site providing the most reliable information.

Therefore, the user may be provided with reliable information on a topic to be found by accessing a website located above the displayed website (S180).

Meanwhile, the ranking determiner 124 selectively stores the website information ranked for each search term in the recommendation information database 132 to provide website information for each rank without a separate evaluation process when the same search term is input later. You can do that.

In the above, embodiments of the present invention have been described in detail, but the present invention is not limited to the above-described embodiments, and various other modifications or changes are possible.

According to the present invention, information retrieval users who want to know about a particular subject are recommended only representative websites on the subject, so that the data on the Internet can be used more efficiently.
