Word similarity computation based on domain ontology
Guo Di-na · Journal of Computer Applications · 2009
The authors considered property similarity,semantic distance,hierarchy depth,regulatory parameters and other factors on the impact of the word similarity based on ontology,and proposed the method of computing word similarity.Experimental result shows that the method combines the hierarchy relations and properties fully in domain ontology.Based on word similarity,it expands vector space model of document.The result of document classification precision is better than traditional one.
