摘要
在深入研究语义相似度计算方法的基础上,提出了一种改进的领域本体概念语义相似度计算法.算法考虑了概念间层次顺序、节点深度、语义重合度对基本语义相似度的影响,描述了决定概念语义相似度的各种因素,分析并建立了这些因素的数学模型.通过实验对比与分析,验证了此算法具有较好的精确性和准确性.
Based on the deep research of semantic similarity algorithm ,an improved semantic similarity algorithm based on domain ontology is proposed ,Hierarchical sequential ,depth information and semantic coincidence degree between concepts are considered ,which affect the basic semantic similarity .Semantic similarity determinant factors are described and analyzed ;the factors’ mathematical models are established .Experiment comparison and analysis verify that ,the precision and accuracy of proposed semantic similarity algorithm are good .
