A survey on sentence fusion techniques of abstractive text summarization

Abstract Sentence fusion is one of the tasks of automatic text summarization that has wide spread applications in the field of computer science. It is currently used in automatic text summarization and question answering systems. It is also used in natural language generation systems in the name of sentence aggregation. The task of sentence fusion poses various challenges like deciding whether two sentences can be combined or not, which part of a sentence should be selected for combination, how these parts can be combined and how to fit the combinations in a grammatically correct sentence structure. In this paper we discuss about the research done on sentence fusion and various challenges that are yet to be met
