Research on Methods of Ontology-Based Class Label Semantic Similarity Computation

The semantic similarity methods during the process of clustering process of the searching engine label by combining ontology are studied and the search model of the clustering engine and web-based class label extraction methods under the Chinese search environment are proposed in this paper. The corresponding formulas and algorithms are proposed from several perspectives: label primitive, DEF and the label hierarchical distance, etc., in the label similarity computation methods. Eventually, the corresponding empirical analysis on the Carrot2 platform of the out source is made.
