Enhancement of keyphrase-based approach of automatic Bangla text summarization

An approach of automatic Bangla text summarization is presented here by enhancing an existing keyphrase-based method. The enhancement is accomplished with three steps as follows: (i) modifying the keyphrases selection process, (ii) including the first sentence in summary if it contains any title word and (iii) counting numerical figure which is presented in digits and words for sentence scoring. Step by step performance analysis of our proposed approach is portrayed for two datasets. Performance is measured with ROUGE (Recall Oriented Understudy for Gisting Evaluation) automatic evaluation package. The results, based on ROUGE-1 and ROUGE-2 scores, show that the proposed enhancement has significant influence for Bangla text summarization over existing keyphrase-based method.
