Representing Events using Fuzzy Temporal Boundaries

摘要: Representing Events Using Fuzzy Temporal Boundaries Shulan Lu (Shulan_Lu@tamu-commerce.edu) Department of Psychology, Texas AM 1991) proposed a representation that contains seven relational primitives. Figure 1 provides an illustration Allen’s event temporal relations. Each double-headed arrow in represents occurs over some time interval, whereas each arrow-head either the beginning or end event. The relation between pair events is described by one predicates. These primitives have been used as basic operators for automated planning and reasoning systems reason with make logical deductions about Abstract This study investigates whether people represent beginnings ends fuzzy frames subsequently construct adopted (1984; categories Constructing relations often requires accurate encoding (or) retrieval events. We recurrent neural network to simulate performance humans representing was given inputs, generated using Zadeh (1975) logic functions, trained judge compared task where they were asked remember reconstruct everyday simulations showed mimicked human judgments correct judgments, preferences toward particular relations, directions error. results support are best thought analogue representations simulated network.

Consider few examples: going work, having dinner at restaurant, meeting friends. these has number subevents. subevents related other dimensions such causal links. Most all, unfold relate temporally. In this paper, term refers something happens place end. Many researchers suggest properties provide framework structured (Allen, 1984; Barsalou, 1999; Freyd, 1987; Graesser, Kassler, Kreuz, & McLain-Allen, 1998). spans (duration) which take place. also locations relative (temporal relations). studies psychology tend treat following another within hierarchy (e.g., no overlapping same level hierarchy). However, when two more occurring, can overlaps time. addition, overlap vary. For events, same. others, neither nor DURING FINISH EQUAL 1: Relations 1991, pp.5). Some crisp, clear cut frames.
