Intelligent browser for TEXPROS

Browsing is a technique which is employed in information retrieval systems to help users formulate their queries and retrieve information. This technique provides users with capabilities of understanding their information needs and gaining system knowledge during the course of the browsing and thus it eases the users' burden of issuing queries. However, a major concern is that users could be lost when they browse a complex and large network without knowing the meanings of its nodes and links. The other concern is the performance of the browsing technique which heavily lies on the interaction between users and the system. We develop a network for browsing by taking into account the dual model of the document processing system (TEXPROS), and a mechanism such that the performance of the browsing can be improved.
