A Tense And Aspect Calculus

This paper focuses on a theory of tense and aspect (the representation of time in natural language) that attempts a formM representation of the relevant liltguistic devices as implication rules in first order logic. It presents a rich ontology as far as verb aspect is concerned, distinguishing between complex patterns and vagueness. Examples and conclusions are drawn from tile comparison between English and Portuguese, pinpointing the importance of contrastive studies both for the understanding and for the evaluation of a general theory of tense and aspect. In the paper, we present the actual translationsof a wide range of phenomena, and a short example.
