基于XML与Web的产品设计知识表示与知识库系统

提出了一种新型的知识库系统。首先提出一种面向产品设计推理的语义关系标记集，该标记集可消除知识语句的歧义并保持原文的自然语言顺序，并为该语义标记集设计相应的XML标记。其次，提出知识文档标记方法、基于XML的概念及概念词典（本体）的定义方法。最后，开发新型知识库系统的原型系统，系统的运用显示新型知识库更易实现基于网络共享与维护。

Presentation of Products' Design Knowledge and Knowledge Base System Based on XML and Web

A new kind of knowledge base system (KBS) is raised. First, a suite of semantic relationships for product design is put forth, which cangive clear indication of semantics of knowledge sentence and keep the sentences in original natural language style. A set of XML tags is raised on thebasis of semantic relationships. The method of marking up knowledge document and the method of defining conception and constructing conceptiondictionary (Ontology) are put forward. One prototype of this kind of KBS is developed, and the results show that this kind of knowledge base iseasier to be shared than other design systems on net, developed and maintained by novices than traditional knowledge base.
