摘　　要：针对语义Web中的本体异构问题,提出了一种基于树结构的多策略本体映射算法,该算法的特点在于:按照数据类型分类进行映射,并采用启发式规则,提高了映射效率;同时考虑了概念的语言相似性、实例相似性和结构相似性,提高了相似度计算的准确性;采用迭代矫正,最终得到正确而完整的映射对.实验结果表明,该算法的查准率和查全率均优于GLUE算法,能有效完成本体间的映射.In order to solve the problem of ontology heterogeneity in semantic web, a tree-based multistrategy ontology mapping algorithm is proposed. The advantages of this algorithm are： mapping in the compatible datatype categories and using heuristic rules can improve mapping efficiency; both linguistic, instance based and structural similarity are used to improve the accuracy of the similarity calculation; an iterative remedy is adopted to obtain correct and complete mappings. The experiment shows that our algorithm＇s precision and recall outperform GLUE algorithm and it can effectively accomplish the mapping between ontologies.
