An New Approach Measuring Semantic Similarity in Hownet 2000
Fang Li · Zhongwen xinxi xuebao · 2007
A basic approach for measuring semantic similarity/distance between words and concepts is to use lexical taxonomy,such as Wordnet. Hownet is a Chinese semantic dictionary,containing abundant semantic information and ontology knowledge,but has quite different construction and architecture.In this paper,we present a new approach using Hownet by drawing in the idea of information theory.We propose that the more semantic information a sememe take,the more powerful it in describing concepts.Then we divide sememe which describes a concept into two set: directly describing part and indirectly describing part.In the experiments,we demonstrate our method have improved performance in measuring semantic similarity between Chinese words.
