Search System, Conceptual Graph, Context-conservingextension, Hyperlink
WebGraph abstracts the hyperlink between web documents into link relationship between keywords. This relationship is used to construct a conceptual graph of the keywords, which is used to build a concept based search system that extends the query and provides domain knowledge. The query is further extended from the limit set by the WebGraph in this study while conserving the context. The user of the search system may further extend the query of the request if the initial result did not turn up satisfactory results by further specifying the user request in order to get satisfactory result of the query.
