Aiming at the problem of the one-sided and incomplete nature for the current concept similarity computation,this paper presents an improved concept semantic similarity computation method which is based on semantic distance.It spreads semantic distance from three sides of the information contained in directed edge,the directed edge type and concept density,turns semantic distance to semantic similarity.At the same time,this paper introduces the dissymmetry factor,and makes the last concept semantic similarity computation more exact.Comparing this method with information-based method,distance-based method and the human subjective judgment,result proves that this method is feasible and valid.
