An Approach to Compute Document Vector Similarity Based on Rough Set and Ontology
Shao Li · Computer and Modernization · 2012
According to the VSM,in the calculation of the document similarity for document indexing words must be independent of the defect,the paper puts forward integration ontology and rough set document similarity calculation method.In this method,not only can use ontology to the conceptual relations accurate reveals that calculation between document concept similarity,but also can combine of rough set,related concept example of attribute importance measure,thus calculation attributes similarity,overcome traditional methods depend on people's prior knowledge this defect,and finally the comprehensive form document semantic vector similarity,and through the experimental analysis shows that this method can greatly improve the accuracy of the document similarity calculation.
