TAILIEUCHUNG - Báo cáo khoa học: "Coherent Citation-Based Summarization of Scientific Papers"

In citation-based summarization, text written by several researchers is leveraged to identify the important aspects of a target paper. Previous work on this problem focused almost exclusively on its extraction aspect (. selecting a representative set of citation sentences that highlight the contribution of the target paper). Meanwhile, the fluency of the produced summaries has been mostly ignored. For example, diversity, readability, cohesion, and ordering of the sentences included in the summary have not been thoroughly considered. This resulted in noisy and confusing summaries. In this work, we present an approach for producing readable and cohesive citation-based summaries. . | Coherent Citation-Based Summarization of Scientific Papers Amjad Abu-Jbara EECS Department University of Michigan Ann Arbor MI USA amjbara@ Dragomir Radev EECS Department and School of Information University of Michigan Ann Arbor MI USA radev@ Abstract In citation-based summarization text written by several researchers is leveraged to identify the important aspects of a target paper.

Meanwhile the fluency of the produced summaries has been mostly ignored. For example diversity readability cohesion and ordering of the sentences included in the summary have not been thoroughly considered. This resulted in noisy and confusing summaries. In this work we present an approach for producing readable and cohesive citation-based summaries. Our experiments show that the proposed approach outperforms several baselines in terms of both extraction quality and fluency. 1 Introduction Scientific research is a cumulative activity. The work of downstream researchers depends on access to upstream discoveries. The footnotes end notes or reference lists within research articles make this accumulation possible. When a reference appears in a scientific paper it is often accompanied by a span of text describing the work being cited. We name the sentence that contains an explicit reference to another paper citation sentence. Citation sentences usually highlight the most important aspects of the cited paper such as the research problem it addresses the method it proposes the good results it reports and even its drawbacks and limitations. By aggregating all the citation sentences that cite a paper we have a rich source of information about 500 it. This information is valuable because human experts have put their efforts to read the paper and summarize its important contributions. One
