摘要:

现有的多文档文摘系统虽然能够成功地提取摘要语句,但存在覆盖率低、重要语句提取不准确、句子冗余和连贯性差等问题。本研究引入了一个新的概念,质心的方法和报告的新技术提取摘要句子的多文档。在这两种技术中,关键词都被用来衡量句子和文档。第一种摘要技术(Sen-Rich)更喜欢最大丰富度的句子。而第二个(Doc-Rich),更喜欢来自质心文档的句子。为了演示新的摘要系统应用程序提取阿拉伯文文档的摘要,我们进行了两个实验。首先,我们应用Rouge测量来比较在TAC 2011上提出的系统之间的新技术。结果表明,Sen-Rich优于ROUGE-S中的所有系统。第二,将该系统应用于多主题文档的摘要。使用人工评估,结果表明,Doc-Rich是优越的,其中总结句的特点是额外的覆盖范围和更多的衔接。

英文摘要:

Current multi-document summarization systems can successfully extract summary sentences, however with many limitations including: low coverage, inaccurate extraction to important sentences, redundancy and poor coherence among the selected sentences. The present study introduces a new concept of centroid approach and reports new techniques for extracting summary sentences for multi-document. In both techniques keyphrases are used to weigh sentences and documents. The first summarization technique (Sen-Rich) prefers maximum richness sentences. While the second (Doc-Rich), prefers sentences from centroid document. To demonstrate the new summarization system application to extract summaries of Arabic documents we performed two experiments. First, we applied Rouge measure to compare the new techniques among systems presented at TAC2011. The results show that Sen-Rich outperformed all systems in ROUGE-S. Second, the system was applied to summarize multi-topic documents. Using human evaluators, the results show that Doc-Rich is the superior, where summary sentences characterized by extra coverage and more cohesion.
