Summarization

Abstract. This paper proposes an effective method to extract salient sentences using contextual information and statistical approaches for Text Summarization. The proposed method combines two consecutive sentences into a bi-gram pseudo sentence so that contextual information is applied to statistical sentence-extraction techniques. Salient bi-gram pseudo sentences are first selected by the statistical sentence-extraction techniques, and then each selected bi-gram pseudo sentence is separated into two single sentences. The second sentence-extraction task for the separated single sentences is performed to make a final text summary. Because the proposed method uses the contextual information with the bi-gram pseudo sentences and combines the statistical sentence-extraction techniques effectively, it can achieve high performance. As a result, the proposed method showed better performance than other sentence-extraction methods in both single- and multi-document summarization
