Analyze the cases that concepts in ontology are similar, establish a concept similarity computation model based on domain ontology; The computation of concept similarity not only considers the semantic distance between concepts, but also considers the conceptual layer factor and superior concepts coincidence degree, quantizing semantic similarity between concepts nodes in ontology network more comprehensively; Based on the food safety emergencies ontology compute the semantic similarity of some concepts, and the computation results show that the new model to the concept similarity computation is effective.
