Ontology matching based on improved algorithm of similarity propagation
Yuchen Fu · Journal of Computer Applications · 2011
In order to solve the semantic heterogeneity and achieve interoperability between Web applications of different ontology and integrating data,an improved matching algorithm of similarity propagation based on RDF graph was proposed.First,it sought to find initial similar seeds by WordNet.Then it expressed ontology as RDF triples through preprocessing.According to the characteristics of RDF graph,it expanded similarity propagation to triples to find probable similar pairs and then calculated similarities by elements' features.The procedure of similarity propagation,finding probable similar pairs and calculating similarities is a cyclic iterative process until it is convergent.The experimental results show that the algorithm is effective and has better time performance.
