Endpoint Relations on Temporal Intervals
June 13, 1988
Allen's interval algebra has become one of the major schemes used in AI for temporal reasoning. However, Allen's algebra has the esthetically displeasing property that the less one knows about the relationship between two intervals, the longer must be the symbolic expression of that knowledge. This paper presents a reformulation of Allen's interval algebra in terms of more primitive relations between intervals, such that less knowledge requires a shorter symbolic expression. In addition, the reformulation results in a significant simplification of Allen's transitivity table.
