概念语义相似度计算是诸多应用普遍面临的问题.文中以简化单本体内概念语义相似度计算为出发点,提出针对边计算法的相似度计算优化算法.利用本体概念间的层次关系优化相似度计算过程.优化算法依据本体内一对概念间的语义相似度求出本体内所有概念间的语义相似度.仿真实验表明,优化算法能有效降低语义相似度计算复杂度,计算速度提高约一倍.
Conceptual semantic similarity calculation is a common problem faced by many applications.In this paper, the similarity calculation algorithm for edge-based algorithms is proposed based on the simplification of concept semantic similarity calculation in single ontology, and the similarity calculation is optimized by the hierarchical relation among ontology concepts Process.The algorithm optimizes the semantic similarity between all the concepts in the ontology based on the semantic similarity between a pair of concepts in the ontology.The simulation results show that the optimization algorithm can effectively reduce the computational complexity of semantic similarity and double the computational speed.
