事件关系表示模型

事件关系的表示及事件推理是基于事件的知识处理的核心内容。文章提出了事件影响因子的概念来刻画事件间相互影响的强弱,给出了一种事件影响因子的计算方法。在此基础上,建立了事件关系图ERM(Event Relationship Map)来描述领域中事件之间的关系。依据事件关系和事件要素可以进行事件推理,重点阐述了ERM上基于关系的事件推理算法。最后,做了一个事件关系推理的实验,结果证明所提模型及算法与人的主观判断相一致,是合理可行的。

The Model of Event Relation Representation

The representations of events relations and event reasoning are the keys for eventsbased knowledge processing. The paper presents the event influence factor to depict the strong and weak of interaction between events, and introduces a method of computing the event influence factor. Then ERM (Event Relation Map) is then constructed to describe domain event relations. The algorithm of event reasoning can be carried out from event relations and event elements, and we focus on event reasoning based on event relation. Finally, an experiment of event reasoning has been carried, and the results prove that the proposed models and algorithms are in line with the human judgments.
