Abstract: When it comes to the existing ontology complex mapping algorithms，most of them can only find simple complex mappings based on string comparison，resulting in low precision and recall.This paper proposes a new complex mapping algorithm based on the inclusion relation and equivalence relation.Experimental results show that the method can find most of the complex mappings existing in the ontologies and has made great improvement on the mapping precision and recall.

摘要： 已有的本体复合映射算法中，绝大部分都只能发现基于字符串比较的简单类型的复合映射，查准率和查全率不高。提出一种基于结点间包含关系和等价关系发现复合映射的方法。实验证明，该方法可以发现本体中包含的绝大部分复合映射，较之现有的复合映射发现算法在查准率和查全率方面有了很大改进。
