An Improved Semantic Similarity Algorithm Based on Domain Ontology

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.
