【摘要】 本文对知识表示的工具之一语义网络做了简单的介绍，并且给出形式化的定义。语义网络作为表示知识的主要方法，成为知识库组成的主要形式，从而引出知识库的维护及推理的实现。我们在研究中发现，将面向对象技术引入语义网络的研究，成为目前的发展方向之一。特别地，对关系的继承属性的研究是本文所关注的问题。本文首先给出此问题提出的背景，并由实例引出算法设计的基本思想。提出从语义网络的表示中获取知识的机制，并给出由语义网络表示转换成谓词逻辑的表示的算法。更多还原

【Abstract】 This paper analyzes,one of tools of knowledge representation,semantic network and proposes the formal definition.The semantic network is the main method of representing knowledge,and is becoming principal form of component of knowledge base,so educes maintaining knowledge base and implementing inference.We find that applying oriented-object technology to semantic network is one of research directions.In particular, the paper concentrated on the inherit charcter of relations,and analyzes the basic idea of algorithm from the instance,and presents a method of acquiring knowledge based on semantic network representation,and the algorithm converting representation of semantic network to representation of predicate logic.更多还原
