Concept Similarity Computation for Domain Ontology
Zuhua Jiang · Computer Engineering and Applications Journal · 2006
With the widespread application of ontology in the fields of information retrieval,artificial intelligence etc,the concept similarity computation of domain ontology has become the focus research field.Currently,most research on concept similarity computation based on is a relation between concepts,however,it does not utilize the concept semantic information completely.The method proposed in the article divides the concept similarity computation into two levels. One the layer of concept semantic initial similarity which computes the concept initial similarity based on the distance between concepts.The other one the layer of concept non-hyponymy relationship similarity.Based on the concept initial similarity,it computes the similarity reflected by the non-hyponymy relations.And through integration computation,we can get the true concept similarity.The experiment shows that the method utilizes the concept semantic information fully and the computation result reasonable.
