Semantic similarity match of ontology concept based on heuristic rules
Zhe Yang · Journal of Computer Applications · 2007
In the hierarchy model of ontology conceptual model,the semantic similarity between two ontology concepts is in inverse proportion to the semantic distance in between.At the same time,the closer the concepts are to the bottom in the hierarchy model,the more information they describe.Therefore,if the deeper the nearest shared ancestor is,the more similar the two concepts are.Considering these two factors,two heuristic rules and the calculating formula were constructed.And the formula was proved reasonable by analyzing an ontology instance.In the formula,there were two experimental parameters,that were decided by the depth of the hierarchy model of ontology.According to the depth at present,the reasonable values of two experimental parameters were given.
