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
