摘要:

因果关系可视化可以帮助人们理解事件的时间链,例如分布式系统中发送的消息,历史冲突中的因果关系,或者政治行为者之间随着时间的推移而发生的相互作用。然而,随着这些事件序列的规模和复杂性的增长,即使是这些可视化也会变得难以使用。在本文中,我们提出使用文本叙述作为数据驱动的讲故事方法来增强因果关系可视化。我们首先提出了一个设计空间,如何文本叙述可以用来描述因果数据。然后,我们展示了一项众包用户研究的结果,参与者被要求从两个因果关系可视化(因果图和Hasse图)中恢复因果关系信息,其中有和没有相关的文本叙述。最后,我们描述了因果关系可视化系统,了解具体的干预措施如何影响因果模型。该系统采用了自动文本叙事机制的基础上,我们的设计空间。我们通过与使用该系统了解复杂事件的专家进行访谈来验证CAUSEWORKS。

英文摘要:

Causality visualization can help people understand temporal chains of events, such as messages sent in a distributed system, cause and effect in a historical conflict, or the interplay between political actors over time. However, as the scale and complexity of these event sequences grows, even these visualizations can become overwhelming to use. In this paper, we propose the use of textual narratives as a data-driven storytelling method to augment causality visualization. We first propose a design space for how textual narratives can be used to describe causal data. We then present results from a crowdsourced user study where participants were asked to recover causality information from two causality visualizations--causal graphs and Hasse diagrams--with and without an associated textual narrative. Finally, we describe CAUSEWORKS, a causality visualization system for understanding how specific interventions influence a causal model. The system incorporates an automatic textual narrative mechanism based on our design space. We validate CAUSEWORKS through interviews with experts who used the system for understanding complex events.
