Abstract:	This dissertation presents a general hypertext model (GHMI) supporting integration of hypertext and information systems through dynamic mapping. Information systems integrated based on this model benefit from hypertext function-alities (such as linking, backtracking, history, guided tours, annotations, etc.) while preserving their own computation capabilities. Although systems supporting integration of hypertext and interface-oriented information systems do exist in hypertext literature, there is no existing model or system effectively supporting integration of hypertext and computation-oriented information systems. GHMI makes its major contributions by both extending and specifying the well-known Dexter Hypertext Reference Model. GHMI extends the Dexter model to overcome its limitations. GHMI also maps its capabilities to the extended Dexter model with appropriate specifications to meet the requirements of our dynamic mapping environment. The extended Dexter functions apply bridge laws in the hypertext knowledge base to map information system objects and relationships to hypertext constructs at run-time. We have implemented GHMI as a prototype to prove its feasibility.
