摘要： 智能超媒体是多媒体技术与专家系统的理想结合，Petri是描述系统行为的形式 化工具。该文利用有色Petri网、扩展OCPN模型，采用立体层次结构，提出了一种基于Petri 网的智能超媒体模型。该模型能较好地描述专家系统中规则的推理、多媒体中各种媒体的链 接与同步以及与用户的交互和表现问题。

Abstract: Intelligent hypermedia is an expert system combined with multimedia technology ideally. Petri net is a formal model to describe systematic behavio r. According to colored Petri net and extended (prioritized) object composi tion Petri net (OCPN) model, this paper presents an intelligent hypermedia mo del using the cubic hierarchy structure which is based on Petri net. It can describe the problem of rule reasoning, link and synchronization of mul timedia, interaction and presentation with user.
