Title: Method for Searching Similar Websites
Inventor: LEE HYUN KOO
IPC: G06F17/30
Filed: 2000-03-27
Abstract: PURPOSE: A method for searching a similar web site is provided to enable a user to search a web site similar to the web site with the user was familiar by enabling a web server to register URLs of web sites and search words and compare a URL the user inputs with an arbitrary search word, thereby enabling the web server to estimate the degree of similarity. CONSTITUTION: A user wants to search a web site similar to a specific web site. The user inputs a URL of the site(10). A web server stores search words including rankings and weight values and makes the first search word group of the search words(12). The user inputs an arbitrary search word to an input window(14). The search word the user inputs is compared with the first search word group. It is judged whether the search term is repeated(16). In case that there's the repeated search word, the search word in the first search word group is removed(18). The search word inputted from the user is inserted into a relevant ranking(20). The second search word group is formed(22). A candidate web site is selected(24). Weight values are given to search words in the second search word group(26).
