概念的语义相似度研究,是知识表示以及信息检索领域中的一个重要内容.选择核函数计算本体图边的权值.求解超图正则化模型得到优化函数,从而将本体图中每个顶点映射成一个实数,通过比较实数间的差值判断两概念的相似程度.实验表明该方法对于计算本体概念间的相对相似度是有效的.
Study semantic similarity of the concept is an important aspect in knowledge representation and information retrieval.Compute the edge weights using kernel function.Obtain the optimization function using hypergraph regularization framework.The function maps the vertices of graph to real numbers.Calculate the relative similarities of concepts by comparing the difference of corresponding values.Experiments show that the method for calculating the relative similarity between the concepts of ontology is efficient.
