摘要:

我们介绍了微博意见摘要(MOS)的任务,并分享了一个数据集的3100个黄金标准的意见摘要,以促进在这一领域的研究。该数据集包含了2年内的推文摘要,涵盖的主题比任何其他公共Twitter摘要数据集都多。摘要本质上是抽象的,由擅长总结新闻文章的记者根据将事实信息(主要故事)与作者意见分开的模板创建。我们的方法不同于以往从社交媒体生成黄金标准摘要的工作,后者通常涉及选择代表性帖子,因此更倾向于提取摘要模型。为了展示数据集的实用性和挑战,我们对一系列抽象和提取的最先进的汇总模型进行了基准测试,并取得了良好的性能,前者的表现优于后者。我们还表明,微调是必要的,以提高性能和调查的好处,使用不同的样本量。

英文摘要:

We introduce the task of microblog opinion summarisation (MOS) and share a dataset of 3100 gold-standard opinion summaries to facilitate research in this domain. The dataset contains summaries of tweets spanning a 2-year period and covers more topics than any other public Twitter summarisation dataset. Summaries are abstractive in nature and have been created by journalists skilled in summarising news articles following a template separating factual information (main story) from author opinions. Our method differs from previous work on generating gold-standard summaries from social media, which usually involves selecting representative posts and thus favours extractive summarisation models. To showcase the dataset's utility and challenges, we benchmark a range of abstractive and extractive state-of-the-art summarisation models and achieve good performance, with the former outperforming the latter. We also show that fine-tuning is necessary to improve performance and investigate the benefits of using different sample sizes.
