Research on similarity based on semantic unit
PU Guo-lin · Jisuanji yingyong yanjiu · 2008
Because of the flaw of previous models,this paper extended the concept attributes by semantic and proposed a method to measure the similarity based on the semantic unit.Used the semantic unit to express the concept implication,and used the support degree to show the contributions of the semantic unit.It did successfully the concept similarity measure by considering the relevance,resemblance,non-symmetry,and the support degree.Looked on the relation as concept,and measured the ontology similarity based on semantic unit.Finally,the experiment proves that this method is better than other me-thods.
