Expertext: From semantic nets to logic Petri nets

摘要

Hypertext systems present textual information in an intuitive way, while expert systems logically solve problems. Expertext is an approach to combining the precision of expert reasoning processes with the browsing capabilities afforded by hypertext. In this paper intelligent hypertext is first modeled with a semantic net. The semantic net formalism is then extended to a Petri net formalism. Finally, a deductive inferencing ability is added to the Petri net formalism. Examples of how an Electronic Yellow Pages might exploit these methods are presented.
