Concepts similarity calculation is the basis for ontology mapping. Vocabulary, meaning of the word, property and instance of concepts are the important facts when calculating concepts similarity. All the facts above are combined and a composite method is proposed to calculate concepts similarity in this paper. In order to keep the effectiveness and comprehensiveness of the method, we combine concepts...
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...
Ontology is an explicit specification of a conceptualization. With the development of semantic Web, there are more and more ontologies. How to achieve the reusing and sharing of knowledge between ontologies has become the key to the development of semantic Web. Based on the analysis of the current technologies, a computation method of parsing the feature of concept in the ontologies and making use...
