  Can the insights of these separate traditions be reconciled and unified? Is it possible to constrain theories of temporal representations and reasoning with the insights and research methodologies of both traditions? In  Steedman 1995  (and  2000,  listed in the Other Internet Resources Section), these important questions are addressed, and a theory is developed that extends action formalisms like the Situation Calculus, and that incorporates many of the insights from linguistic semantics. The project reported in  Steedman 2000  is still incomplete, but the results reported there make a convincing case that the event-based ideas from linguistics can be fruitfully combined with the action-centered formalisms in the AI literature. The possibility of this unification is one of the most exciting logical developments in this area, bringing together as it does two independent descendants of the earlier work in the logic of time.
