基于情境的文本中的时间信息分析

情境用来描述文本中具体的动态和静态事件,时间是其重要因素·为了分析文本中的时间信息,本文首先给出了一个基于情境的文本理解的模型,并在时态逻辑的基础上,提出了文本的时间信息分析方法,它是将事物发展变化的时间顺序作为理解文本的一条重要线索·其主要工作包括:讨论了时间的概念、时间的类型和时间单位的转换机制；分析了命题间的时间关系、对象行为间的时间关系以及事件状态与时间过程的关系；并给出了所使用的时态逻辑

Temporal Information Analysis for Texts Based on Situations

To analyze time message of a text, a text understanding model was constructed and a set of temporal logic used in analysis was given. A universal calculation method of temporal semantics based on situations was presented.The temporal sequences of event is considered as a value clue to understand the text.The temporal concept, temporal type and transition mechanisms of temporal unit were discussed.The various temporal relations among propositions, behaviors of objects,states of events and temporal procedures were analyzed. Moreover, A set of temporal logic as base of temporal analysis was given.
