摘　　要：提出了一种基于上下文的语义映射方法 SM-Context(semantic mapping based on context)。SM-Context首先为本体模型中的概念找出表示其语义信息的上下文,然后采用谓词逻辑的形式表示概念的上下文,最后将本体映射问题转换成命题可满足性问题(SAT),并通过推理方式建立本体之间的语义映射关系。为了验证所提方法在处理本体映射问题时的可行性与有效性,采用OAEI所提供的共享数据集来测试SM-Context。实验结果表明,SM-Context可以有效地利用概念的上下文为本体之间建立语义映射关系。This paper proposed a semantic mapping method based on context, called SM-Context. Firstly, SM-Context found out the context that represented the semantic information contained by concept. Then, it represented the concept context as a formula of predicate logic. Finally, it encoded the mapping problem as the problem of propositional satisfiability （ SAT）, and created semantic mappings between ontologies by the method of logic deduce. In order to verify the feasibility and effectiveness of SM-Context, this paper applied the shared ontology sets in 0AEI to test SM-Context. Experimental results show that the method SM-Context is able to create semantic mappings between ontologies by the context of concept.
