CONSTITUTION: The system comprises a server(1) and a client(2). The client comprises a plug-in program(Concept Wizard:CW,4) in order to formulate and refine the natural language query of user. The client exchanges the data with the server by calling the HTTP(Hypertext Transport Protocol Daemon) or CGI(Common Gateway Interface) of server through a browser(3). The server extracts the keywords from the natural language query by a user's search request and transmits the conceptual keywords corresponding to each keyword through a thesaurus together with the extracted keywords to the CW. The user selects the desired keywords from the received keyword, refines the detail weight by using the CW, and easily formulates the query by the manipulation of mouse.
