一种改进的本体概念语义相似度计算方法

摘要

本文分析了几种概念相似度的运算方法，对概念相似度计算模型进行了改进，该计算模型在计算初始主流概念相似度的基础上，不仅引入了深度、密度因子，还考虑了有向边类型权重因子在计算相似度中所起的作用，完善了计算方法。通过试验结果可以看出，该方法对概念相似度的计算更准确地体现出了概念间的相似程度。%A new modify model of computing the similarity of concepts is proposed by analyzing the traditional methods of con-ceptual similarity. Based on the computation of initial semantic similarity, the influences of the depth and intensity between concepts and the effect of the type of edges are taken into account. Experimental result shows that this method is feasible in improving the ac-curacy of computing the semantic similarity of concepts.
