Abstract
Keyword ranking with similarity identification is an approach to find the significant Keywords in a corpus using a Variant Term Frequency Inverse Document Frequency (VTF-IDF) algorithm. Some of these may have same similarity and they get reduced to a single term when WordNet is used. The proposed approach that does not require any test or training set, assigns sentence based Weightage to the keywords(terms) and it is found to be effective. Its suitability is analyzed with several data sets using precision and recall as metrics.
