TAILIEUCHUNG - Báo cáo khoa học: "INTENTIONS AND INFORMATION IN DISCOURSE"

This paper is about the flow of inference between communicative intentions, discourse structure and the domain during discourse processing. We augment a theory of discourse interpretation with a theory of distinct mental attitudes and reasoning about them, in order to provide an account of how the attitudes interact with reasoning about discourse structure. INTRODUCTION The flow of inference between communicative intentions and domain information is often essential to discourse processing. | INTENTIONS AND INFORMATION IN DISCOURSE Nicholas Asher IRIT Université Paul Sabatier 118 Route de Narbonne 31062 Toulouse CEDEX France Abstract This paper is about the flow of inference between communicative intentions discourse structure and the domain during discourse processing. We augment a theory of discourse interpretation with a theory of distinct mental attitudes and reasoning about them in order to provide an account of how the attitudes interact with reasoning about discourse structure. INTRODUCTION The flow of inference between communicative intentions and domain information is often essential to discourse processing. It is well reflected in this discourse from Moore and Pollack 1992 l a. George Bush supports big business. b. He s sure to veto House Bill 1711. There are at least three different interpretations. Consider Context 1 in this context the interpreter I believes that the author A wants to convince him that lb is true. For example the context is one in which I has already uttered Bush won t veto any more bills. I reasons that A s linguistic behavior was intentional and therefore that A believes that by saying la he will convince I that Bush will veto the bill. Even if I believed nothing about the bill he now infers it s bad for big business. So we have witnessed an inference from premises that involve the desires and beliefs of A Moore and Pollack s intentional structure as well as his linguistic behavior to a conclusion about domain information Moore and Pollack s informational structure . Now consider Context 2 in this context I knows that A wants to convince him of la . As in Context 1 I may infer that the bill is bad for big business. But now lb is used to support la . Finally consider Context 3 in this context I knows that House Bill 1711 is bad for big business but doesn t know A s communicative desires prior to witnessing his linguistic behaviour. From his beliefs about the domain he infers that supporting big business would
