TY - JOUR T1 - Document Summarization Considering Entailment Relation between Sentences AU - Kwon, Youngdae AU - Kim, Noo-ri AU - Lee, Jee-Hyong JO - Journal of KIISE, JOK PY - 2017 DA - 2017/1/14 DO - KW - document summarization KW - entailment relation inference KW - natural language processing KW - TextRank KW - recurrent neural network AB - Document summarization aims to generate a summary that is consistent and contains the highly related sentences in a document. In this study, we implemented for document summarization that extracts highly related sentences from a whole document by considering both similarities and entailment relations between sentences. Accordingly, we proposed a new algorithm, TextRank-NLI, which combines a Recurrent Neural Network based Natural Language Inference model and a Graphbased ranking algorithm used in single document extraction-based summarization task. In order to evaluate the performance of the new algorithm, we conducted experiments using the same datasets as used in TextRank algorithm. The results indicated that TextRank-NLI showed 2.3% improvement in performance, as compared to TextRank.
