一种基于语义关系计算领域本体中概念间语义相关度的方法

摘要

We define Degree of semantic Association (DOA) for SA to describe the semantic association from a concept to its direct-related concept in the domain ontology. DOA comes from the intuition that each type of semantic relationship implies semantic association at a certain extent. A Method MBSR is given to compute DOA based on semantic relationships. DOA starts from a probability P<,y> (x/r) and is developed on the ground of domain corpus, where x and y are two concepts in ontology and r is the semantic relationship from y to x. MDOA to describe the degree of semantic association of any two concepts is also given.
