Sentence Ordering Techniques in Multi Document Summarization

Extracting salient information to include in a summary has been researched extensively in the field of automatic text summarization. However, coherent arrangement of the extracted information has not received much attention. Specially, in the case of extractive multi-document text summarization, sentences that convey important information are selected from a set of documents. There is no guarantee that this set of extracted sentences will form a coherent summary by itself. The order of presentation of information extracted is an important factor and affects the coherence of a summary. This paper focuses on the various techniques for generating a coherent summary from a given set of documents by ordering the extracted sentences. In our previous paper "Approaches to Summarize Multi Documents Using Information Extraction" we discussed the approaches for information extraction, in this paper we are introducing various approaches for sentence ordering of extracted information in multi document summarization.
