摘要： 针对本体异构问题，提出基于概念相似度计算的多策略映射方法。选择过滤候选概念集及信息增益计算策略，缩小概念范围，减少计算量。计算时采用基于名称、概念属性和概念关系策略，并综合考虑实例相似度和结构相似度，通过赋予权值进行相似度合并，最终得到准确而完整的映射对。实验结果表明，该方法总体映射效果良好。

Abstract: In order to solve the problem of ontology heterogeneity in semantic Web, a multi-strategy ontology mapping algorithm based on conceptual similarity computing is proposed. The candidate set and information gain are brought to simplify the calculation process. Calculating of conceptual similarity is based on name, conceptual attribute, conceptual relation, instance similarity and structure similarity. Correct and complete mappings are finally obtained through combination of all these similarities. Experimental result shows that the algorithm is more effective.

Key words: ontology, mapping, conceptual similarity
