一种本体概念的语义相似度计算方法
A Semantic Similarity Measure between Ontological Concepts
摘要
Abstract
Concept semantic similarity is wildly used in web service matchmaking, ontology mapping and so on. But the existing concepts semantic similarity measuring methods cannot distinguish the similarities further. So in this paper, we firstly propose a bottom-up concept probability computation method based on ontology structure, and based on this probability, we improve an information content based semantic similarity method. Then, we design an edge based concept semantic similarity method. Finally, we linearly combine the two previous semantic similarity methods to form a weighted one. Result shows that the weighted one can distinguish similarity between concept and its children, or between siblings.关键词
