摘　　要：一般，用逻辑形式表示时态信息的方法是命题附加一个时间点或时间区间。文［１］指出，时间区间表示单个事件带间断区间是困难的，不过，文［１］定义两个间断区间的时态关系为一个矩阵，其计算量相当之大以至该方法不实用二本文给出一个基于间断区间的时态知识表示模型，它将两个间断区间的时态关系分为２０种，其计算量与Ａｌｌｅｎ的区间演算属同一数量级。Generally, one way to represent temporal information in a logical formalism is by associating 'proposition types' with time points or time intervals. It was pointed out that time intervals are difficult to represent the common sense notion of a single event with 'gaps' in [1]. However, the temporal relations of two gap -intervals defined in [1] are expressed in a matrix. The computing amount of temporal relations is so large that the method in [1] is not useful. This paper presents a interval-gap-based representation of temporal knowledge. Its temporal relations are stipulated to 20, and its computing amount is in same level to Allen's.
