Concept Semantic Similarity Researching Based on WordNet

The Suggested Upper Merged Ontology(WORDNET) [1] is an effort by the Standard Upper Ontology Working Group of IEEE.The goal is to develop the Standard Upper Ontology,and it will encourage interoperability,information searching,automatic reasoning and natural language processing.In this paper we propose a method for computing the semantic similarity of two concepts,and it is implemented as a computing module.Finally,we compare the results got from the program with the judgments of subjects.Through this experiment,the method is proved valid.Our research can be applied in the field of knowledge searching,and it provides a basis of theory for the relative research on ontology.
