许多真实世界的应用程序,从原始数据中获得的事件的原因必须处理的时间不确定性的问题,这是由于错误或不准确的数据。不确定性也会影响需要推断事件之间关系的推理。本文讨论了一种使用可能性理论处理时间和因果关系中的不确定性的方法,重点是一个家庭的医疗决策支持系统,旨在从新生儿重症监护室的原始患者数据生成文本摘要。我们描述了一个框架来捕捉时间的不确定性,并表示它在生成的文本中的语言修饰语。这些修饰语是根据一项人类实验选择的,该实验测试了对一个命题的主观确定性与参与者表达它的方式之间的联系。
Many real-world applications that reason about events obtained from raw data must deal with the problem of temporal uncertainty, which arises due to error or inaccuracy in data. Uncertainty also compromises reasoning where relationships between events need to be inferred. This paper discusses an approach to dealing with uncertainty in temporal and causal relations using Possibility Theory, focusing on a family of medical decision support systems that aim to generate textual summaries from raw patient data in a Neonatal Intensive Care Unit. We describe a framework to capture temporal uncertainty and to express it in generated texts by mean of linguistic modifiers. These modifiers have been chosen based on a human experiment testing the association between subjective certainty about a proposition and the participants' way of verbalising it.
