Abstract: With the gradual maturing of Ontological technology, how to establish the semantic bridge among Ontologies is becoming the new hotspot of current researches in order to reuse and share knowledgies. Based on analyzing current technologies, a method viaing the features of Ontologies were parsed and making use of semantic similarity measurement techniques to find the same or similar concepts pair between different Ontologies was proposed and was used in the process of Ontology mapping, which proved to be feasible by experiments.

Key words: mapping, semantic similarity, concept, Ontology

摘要： 随着本体技术的逐渐成熟，如何为本体搭建语义桥梁以实现知识的重用与共享成为新的研究热点。在分析现有相关技术的基础上，提出通过解析本体中概念的特征并借助语义相似度度量技术找到不同本体间相同或相近的概念对的计算方法，同时用于本体映射过程中。实验证明，该方法具有良好的效果。
