摘要:

由于机器学习技术的最新进展,自动文本摘要的任务已经获得了很大的牵引力。然而,评估生成的摘要的质量仍然是一个悬而未决的问题。文献已广泛采用面向回忆的替代评价(ROUGE)作为摘要的标准评价指标。然而,ROUGE有一些长期存在的局限性;一个主要的局限性是它依赖于高质量的参考摘要的可用性。在这项工作中,我们提出了度量WIDAR,除了利用参考摘要还使用输入文件,以评估生成的摘要的质量。所提出的度量是通用的,因为它的目的是根据参考摘要的质量来调整评价分数。在SummEval数据集中提供的人类判断分数的连贯性,一致性,流畅性和相关性方面,所提出的度量分别比ROUGE好26%,76%,82%和15%。所提出的度量是能够获得与其他国家的最先进的指标,同时需要一个相对较短的计算时间的结果。

英文摘要:

The task of automatic text summarization has gained a lot of traction due to the recent advancements in machine learning techniques. However, evaluating the quality of a generated summary remains to be an open problem. The literature has widely adopted Recall-Oriented Understudy for Gisting Evaluation (ROUGE) as the standard evaluation metric for summarization. However, ROUGE has some long-established limitations; a major one being its dependence on the availability of good quality reference summary. In this work, we propose the metric WIDAR which in addition to utilizing the reference summary uses also the input document in order to evaluate the quality of the generated summary. The proposed metric is versatile, since it is designed to adapt the evaluation score according to the quality of the reference summary. The proposed metric correlates better than ROUGE by 26%, 76%, 82%, and 15%, respectively, in coherence, consistency, fluency, and relevance on human judgement scores provided in the SummEval dataset. The proposed metric is able to obtain comparable results with other state-of-the-art metrics while requiring a relatively short computational time.
