The traditional expert system can not be used to solve the problems of process reasoning effectively,but the technology of ontology and semantic inference can be used to offer the valid solution for the lack of knowledge acquisition and intelligent inference of expert system.The ontology,SWRL rule and the relevant inference engine are introduced,the inference process of process based on ontology and the SWRL rule is proposed,the construction method of the process ontology and the writing standards of SWRL rule are described in detail,and then,the results of process inference are given not in this paper.%传统的专家系统并不能有效解决工艺推理问题,但本体技术和语义推理技术为解决专家系统在知识获取以及智能化推理方面的不足提供了有效解决方案.首先介绍本体知识、SWRL规则、相关推理引擎等;其次提出了基于本体与SWRL规则的工艺推理整体流程,并详细描述了工艺知识本体的构建方法;随后结合实例说明SWRL规则编写规范,并验证了该工艺推理方法的可行性.
