本文分析了传统名称策略在本体映射中的不足。针对此问题，提出了一种新的基于WordNet 名称策略算法，该算法实现名称核心词汇的WordNet 定位用以消除词义模糊性，从而提高词相似度计算的精确度，并在词相似度合并中采用C-C 原则，改善传统词相似度合并的盲目性。实验结果显示，该算法在保证查全率的同时有效的提高了查准率。

Abstract: This paper analyzes the main drawbacks of traditional name-based strategies for
ontology mapping. To solve the problems of name-based strategies, a new solution based on
WordNet is proposed. This solution maps core words of a concept to the WordNet to eliminate word ambiguity, using this approach will improve the accuracy of similarity calculation between words, and a C-C principle is adopted to solve the blindness problem which usually exists when combining similarity value between words. Experiment results show that this algorithm efficiently improves the precision while maintaining recall.
