Improved algorithm of structure strategy in ontology matching

Similarity propagation is essential step for structure strategy.However,the existing algorithm of similarity propagation does not take a reasonable quantitative analysis for propagated value.To solve this problem,a new algorithm of similarity propagation is proposed which based on information content of concept,information content of concept is acquired by the context of ontology structure,and propagated value is adjusted by the value of information content of concept to obtain a more accuracy propagated value.Theoretical analysis and the results of experiment is shown that the improved algorithm is efficient.
