A Compositive Approach for Semantic Similarity Computation of Concepts
Taihua Fan · Computer Knowledge and Technology · 2011
To aim at the one-sided and incomplete issues of the computation of concept similarity,this paper puts forward a compositive approach.Firstly,based on the traditional semantic distance,considering the type of directed edges-IS-Acategory relations,density,direction and other factors,it can compute a similarity.Then,according to the elements of the ontology five-tuple,it can calculate the similarity of concepts.Finally,in order to realize the adaptability of each similarity with the regulatory factor,it use the sigmoid threshold function to calculate the value of the regulatory factor corresponding to each similarity,and then calculate comprehensively.Experiments show that the method is effective and accurate.
