论文摘要
了解什么导致有效的对话可以帮助设计更好的计算机介导的通信平台。特别是,先前的观察工作试图确定与他们的对话效率相关的个体的行为。但是,将这种相关性转化为因果解释是以规定的方式使用它们来指导更好的设计和政策的必要步骤。 在这项工作中,我们正式描述了在对话行为和结果之间建立因果关系的问题。我们专注于确定基于文本的危机咨询平台的特定政策类型的任务:如何根据他们过去对话中表现出的行为倾向最好地分配辅导员。我们将因果推论得出的论点应用于在很难实施随机试验的会话环境中引起的突出关键挑战。最后,我们展示了如何在我们特定领域中规避这些推论挑战,并说明了由结果的规定信息所告知的分配策略的潜在好处。
Understanding what leads to effective conversations can aid the design of better computer-mediated communication platforms. In particular, prior observational work has sought to identify behaviors of individuals that correlate to their conversational efficiency. However, translating such correlations to causal interpretations is a necessary step in using them in a prescriptive fashion to guide better designs and policies. In this work, we formally describe the problem of drawing causal links between conversational behaviors and outcomes. We focus on the task of determining a particular type of policy for a text-based crisis counseling platform: how best to allocate counselors based on their behavioral tendencies exhibited in their past conversations. We apply arguments derived from causal inference to underline key challenges that arise in conversational settings where randomized trials are hard to implement. Finally, we show how to circumvent these inference challenges in our particular domain, and illustrate the potential benefits of an allocation policy informed by the resulting prescriptive information.
