Research on the Measuring of Semantic Similarity Based Ontology
Sheng Qiu-yan · Information Sciences · 2012
The research about word similarity is very important in knowledge representation and information retrieval.Semantic similarity is divided into concept similarity and description similarity.A calculation of semantic similarity between concepts in ontology is presented by the hierarchy of ontology concepts.To make the calculation of semantic similarity between concepts more similar to human's subjective judgment,semantic similarity is divided into concept similarity and description similarity;the final semantic similarity is produced by merging concept similarity and description similarity.The optimized parameter settings are gained through the experiment results.
