ABSTRACT
TBox with time interval. Villafane [2000] proposed to express the inclusion relation between time events by algorithm. Mo Sunzhi et al. [2005] proposed a model to express inaccurate time and tense relations based on the fuzzy sets. Lin Chuang et al. [2001] proposed a method to represent imprecise time interval by increasing extended period of time on the right of a certain time interval, however, the model does not explain how to determine the length of extended periods. Liu Wei [2012] proposed a time-dimensional description logic T-ALC from the perspective of event action and put forward reasoning relations between actions with regard to time. However, no scholars use the main line of the time of occurrence of events and according to the relationship of the time point and time interval and combined with the rules of the relationship to research the relationship of events.
