摘要:

基于社区的问答(CQA)允许用户获取他们想要的信息,已经越来越多地成为电子商务、旅游和餐饮等各个领域的在线服务的重要组成部分。然而,大量的CQA对使得没有特定意图的用户难以找到散布在CQA对上的有用信息。为了帮助用户快速消化关键信息,我们提出了新的CQA摘要任务,旨在从CQA对创建一个简洁的摘要。为此,我们首先设计了一个多阶段的数据注释过程,并基于Amazon QA语料库创建了一个基准数据集CoQASUM。然后,我们比较了一系列提取和抽象摘要方法,并为CQA摘要任务建立了一个强大的基线方法DedupLED。我们的实验进一步证实了CQA摘要任务面临的两个关键挑战,即重复类型传输和重复删除。我们的数据和代码是公开的。

英文摘要:

Community-based Question Answering (CQA), which allows users to acquire their desired information, has increasingly become an essential component of online services in various domains such as E-commerce, travel, and dining. However, an overwhelming number of CQA pairs makes it difficult for users without particular intent to find useful information spread over CQA pairs. To help users quickly digest the key information, we propose the novel CQA summarization task that aims to create a concise summary from CQA pairs. To this end, we first design a multi-stage data annotation process and create a benchmark dataset, CoQASUM, based on the Amazon QA corpus. We then compare a collection of extractive and abstractive summarization methods and establish a strong baseline approach DedupLED for the CQA summarization task. Our experiment further confirms two key challenges, sentence-type transfer and deduplication removal, towards the CQA summarization task. Our data and code are publicly available.
