摘要:

比较或整合多个文档中信息的NLP模型在识别文本中大量信息冗余的挑战时往往会遇到困难。例如,在多文档摘要中,识别跨文本的显著信息,然后生成非冗余摘要是至关重要的,同时面对重复的且通常措辞不同的显著内容。为了便于研究这些挑战,提出了\textit{sentence fusion}的任务级别,但以前用于该任务的数据集在大小和范围上非常有限。在本文中,我们重新审视并大大扩展了以前的数据集创建工作。通过仔细修改,重新标记和采用补充数据源,我们能够将早期数据集的大小增加两倍。此外,我们还证明了我们的扩展版本在多文档任务中使用了更具代表性的文本,并提供了更大、更多样化的训练集,这大大改善了模型训练。

英文摘要:

NLP models that compare or consolidate information across multiple documents often struggle when challenged with recognizing substantial information redundancies across the texts. For example, in multi-document summarization it is crucial to identify salient information across texts and then generate a non-redundant summary, while facing repeated and usually differently-phrased salient content. To facilitate researching such challenges, the sentence-level task of \textit{sentence fusion} was proposed, yet previous datasets for this task were very limited in their size and scope. In this paper, we revisit and substantially extend previous dataset creation efforts. With careful modifications, relabeling and employing complementing data sources, we were able to triple the size of a notable earlier dataset. Moreover, we show that our extended version uses more representative texts for multi-document tasks and provides a larger and more diverse training set, which substantially improves model training.
