HyTEXPROS: a hypermedia information retrieval system

TEXPROS is an intelligent document processing and retrieval system, which supports storing, extracting, classifying, categorizing, retrieving and browsing information and documents. We extend TEXPROS to a hypermedia information retrieval system called HyTEXPROS with hypertext functionalities. It describes the whole information base as a network of nodes connected with links, including the metadata and the original documents. Through hypertext functionalities, a user can construct dynamically an information path by browsing through pieces of the information base. A three-level conceptual architecture is presented as the reference model of HyTEXPROS. A detailed description of HyTEXPROS using the first order logic calculus is also proposed
