摘要/Abstract

摘要：

针对传统信息量计算方法中仅考虑WordNet内的上下位关系, 而未考虑部分整体关系问题, 提出一种基于扩展关系的信息量计算方法, 并验证了该方法的优越性. 应用该方法能改进词语或概念的语义相似度计算结果.

关键词: 信息量, 语义相似度, WordNet层次结构

Abstract:

According to the problem of the traditional information content method depending on WordNet structure, only the Hypernym/Hyponym relation is considered in this method. However, the Holonym/Meronym relation which is also important has not been considered. Therefore, a method based on extending relations was given in this paper. According to the experiments, the method is better. The result of the semantic similarity between words or concepts can be improved according to the method.

Key words: information content, semantic similarity, WordNet structure
