Towards a Formalization of Tense and Aspect for the Generation of Portuguese Sentences

In this paper, we present an implemented generator of sentences in Portuguese that takes into account tense and aspect, especially the compound forms with the auxiliaries estar and ser. In Portuguese, the interpretation of the auxiliary estar is very similar to the English auxiliary to be when it is combined with a gerund to produce the progressive form. But it has many different interpretations when combined with a verb in the past participle form. In fact, the aspect system in Portuguese is very complex. It has been studied by many people in an interpretation perspective (see [5, 3]). But if we consider the generation perspective, we did not find any work giving some insight on how to achieve it. Our work is thus a fist step in this direction. After a short introduction of the notion of aspect we adopted, we provide an overall description of our grammar.
