AI总结:

本研究聚焦新闻文本叙事结构自动检测任务,构建了首个新闻叙事结构数据集CompRes,设计适配新闻的标注方案并训练监督模型,最高F₁达0.7,为相关研究提供了数据与方法基础。

摘要:

本文针对原始文本中叙事结构的自动检测任务展开研究。以往研究借助Labov和Waletzky的口头叙事理论,识别个人故事文本中的各类叙事元素。而本文将研究焦点转向新闻文章,动因在于新闻的社会影响力日益提升,且其在塑造公众舆论方面发挥着重要作用。\n 我们推出了CompRes——首个面向新闻媒体叙事结构的数据集。本文详述了该数据集的构建流程:首先,我们适配Labov和Waletzky叙事理论中的元素(Complication(冲突)与Resolution(解决)),并新增了一个原创叙事元素(Success(成效)),设计出一套更适配新闻媒体的全新叙事标注方案;随后,我们使用该方案对从新闻网站和党派网站收集的29篇英文新闻文章(共含1099个句子)进行标注。我们利用标注后的数据集训练了多个监督模型以识别不同叙事元素,最高取得了0.7的F₁分数。最后,本文提出了若干颇具前景的未来研究方向。

英文摘要:

This paper addresses the task of automatically detecting narrative structures in raw texts. Previous works have utilized the oral narrative theory by Labov and Waletzky to identify various narrative elements in personal stories texts. Instead, we direct our focus to news articles, motivated by their growing social impact as well as their role in creating and shaping public opinion. We introduce CompRes -- the first dataset for narrative structure in news media. We describe the process in which the dataset was constructed: first, we designed a new narrative annotation scheme, better suited for news media, by adapting elements from the narrative theory of Labov and Waletzky (Complication and Resolution) and adding a new narrative element of our own (Success); then, we used that scheme to annotate a set of 29 English news articles (containing 1,099 sentences) collected from news and partisan websites. We use the annotated dataset to train several supervised models to identify the different narrative elements, achieving an $F_1$ score of up to 0.7. We conclude by suggesting several promising directions for future work.
