Abstract

The Hypermedia information retrieval system makes use of the specific capabilities of hypermedia systems with information retrieval operations and provides new kind of information management tools. It combines both hypermedia and information retrieval to offer end-users the possibility of navigating, browsing and searching a large collection of documents to satisfy an information need. TEXPROS is an intelligent document processing and retrieval system that supports storing, extracting, classifying, categorizing, retrieval and browsing enterprise information. TEXPROS is a perfect application to apply hypermedia information retrieval techniques. In this dissertation, we extend TEXPROS to a hypermedia information retrieval system called HyTEXPROS with hypertext functionalities, such as node, typed and weighted links, anchors, guided-tours, network overview, bookmarks, annotations and comments, and external linkbase. It describes the whole information base including the metadata and the original documents as network nodes connected by links. Through hypertext functionalities, a user can construct dynamically an information path by browsing through pieces of the information base. By adding hypertext functionalities to TEXPROS, HyTEXPROS is created. It changes its working domain from a personal document process domain to a personal library domain accompanied with citation techniques to process original documents. A four-level conceptual architecture is presented as the system architecture of HyTEXPROS. Such architecture is also referred to as the reference model of HyTEXPROS. Detailed description of HyTEXPROS, using the First Order Logic Calculus, is also proposed. An early version of a prototype is briefly described.
