本体推理是语义网研究的一个热点问题，目前大多数查询系统都是专家系统，但在

专家系统中，知识的表现形式都存在各种不足，本文在借鉴原有专家系统优点的基础之上，

介绍了一个基于SWRL 推理机制的框架，它弥补了专家系统中的不足之处，解决了以往的

本体不能表示“if...then...”这样句式规则的缺点，另外利用本体技术使我们的系统在其它类似

的系统中可以重复使用。-Ontology inference is a hot issue in the studies of Semantic Web. At present, Most inquiry systems are

all expert systems, but there are various deficiencies in expression forms of expert systems knowledge.

In this paper, on the basis of referring to the advantages of original expert systems, a framework of

SWRL-based reasoning mechanism is introduced. It makes up for the deficiency of expert systems and

solve the shortcoming that the original ontology can not express the rule sentences such as”if... then ...”.

In addition, our systems can be used repeatedly in other similar systems by the ontology technology.
