脚本知识的因果推理
Causal Inference of Script Knowledge
摘要:
一系列事件何时定义了一个日常场景,如何从文本中归纳出这种知识?先前的工作在诱导这样的脚本依赖于,在一种形式或另一种,在语料库中的事件的实例之间的相关性的措施。我们认为,从概念和实践意义上说,一个纯粹的相关性为基础的方法是不够的,而是提出了一种方法,脚本感应事件之间的因果关系的基础上,通过干预正式定义。通过人工和自动评估,我们表明基于因果效应的方法的输出更好地匹配脚本所代表的直觉
英文摘要:
When does a sequence of events define an everyday scenario and how can this knowledge be induced from text? Prior works in inducing such scripts have relied on, in one form or another, measures of correlation between instances of events in a corpus. We argue from both a conceptual and practical sense that a purely correlation-based approach is insufficient, and instead propose an approach to script induction based on the causal effect between events, formally defined via interventions. Through both human and automatic evaluations, we show that the output of our method based on causal effects better matches the intuition of what a script represents
