Ontology Concept Similarity Computation Based on Graph Learning
Yungang Zhang · Journal of Southwest China Normal University · 2011
To study semantic similarity of the concept is an important aspect in a knowledge representation and information retrieval.Compute the edge weights according to the type of edge,vertex depth,density and intensity of edges and attributes of vertices associated with edges.Obtain the optimization function using graph 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.
