Study of Concept Similarity Algorithm Based on Ontology Structure

According to the structural characteristics of Ontology model, analyze the concept similarity computation basing on the width, depth and density among the concepts of Ontology model. Consider these aspects as structural fact and combine other facts such as semantic contact ratio and semantic distance, an algorithm of semantic similarity computation based on ontology structure is proposed. Through constructing Ontology model and the analysis experiment, summarizing the effects to the Ontology concepts semantic similarity of different facts about Ontology structure.
