理解和生成道德故事的语料库

A Corpus for Understanding and Generating Moral Stories

Tsinghua University(清华大学)

Jian Guan, Ziqi Liu, Minlie Huang

摘要:

讲故事的最重要目的之一是教导道德。理解和写作道德故事的一个基本能力是连接故事情节和隐含的道德。其挑战主要在于:(1)掌握道德中抽象概念的知识,(2)捕捉故事中事件间的话语关系,(3)调整故事和道德关于好或坏行为的价值偏好。在本文中,我们提出了两个理解任务和两个生成任务来评估这些能力的机器。我们提出了STORAL,一个新的数据集的中文和英文人类写的道德故事。我们所提出的任务的难度,通过测试各种型号的自动和手动评估STORAL。此外,我们提出了一个检索增强算法,有效地利用相关的概念或事件的训练集作为额外的指导,以提高这些任务的性能。

英文摘要:

Teaching morals is one of the most important purposes of storytelling. An essential ability for understanding and writing moral stories is bridging story plots and implied morals. Its challenges mainly lie in: (1) grasping knowledge about abstract concepts in morals, (2) capturing inter-event discourse relations in stories, and (3) aligning value preferences of stories and morals concerning good or bad behavior. In this paper, we propose two understanding tasks and two generation tasks to assess these abilities of machines. We present STORAL, a new dataset of Chinese and English human-written moral stories. We show the difficulty of the proposed tasks by testing various models with automatic and manual evaluation on STORAL. Furthermore, we present a retrieval-augmented algorithm that effectively exploits related concepts or events in training sets as additional guidance to improve performance on these tasks.
