Automatic Keyword Extraction from Bengali Text Using Improved RAKE Approach

Abstract

Keyword extraction refers to the identification of words or short phrases that concisely describe the contents of the document. Rapid Automatic Keyword Extraction (RAKE) is a well-known keyword extraction approach. But we found that RAKE fails to extract the significant Bengali keywords. In this paper, we have proposed an improved version of the pristine RAKE called RAKEB. We have also shown that RAKEB works significantly well for Bengali than the pristine RAKE.
