TAILIEUCHUNG - Báo cáo khoa học: "PROVIDING A UNIFIED ACCOUNT OF DEFINITE NOUN PHRASES IN DISCOURSE"

Linguistic theories typically assign various linguistic phenomena to one of the categories, syntactic, semantic, or pragmatic, as if the phenomena in each category were relatively independent of those in the others. However, various phenomena in discourse do not seem to yield comfortably to any account that is strictly a syntactic or semantic or pragmatic one. This paper focuses on particular phenomena of this s o r t - t h e use of various referring expressions such as definite noun phrases and pronouns-and examines their interaction with mechanisms used to maintain discourse coherence. . | PROVIDING A UNIFIED ACCOUNT OF DEFINITE NOUN PHRASES IN DISCOURSE Barbara J.

Overview Linguistic theories typically assign various linguistic phenomena to one of the categories syntactic semantic or pragmatic as if the phenomena in each category were relatively independent of those in the others. However various phenomena in discourse do not seem to yield comfortably to any account that is strictly a syntactic or semantic or pragmatic one. This paper focuses on particular phenomena of this sort the use of various referring expressions such as definite noun phrases and pronouns and examines their interaction with mechanisms used to maintain discourse coherence. Even a casual survey of the literature on definite descriptions and referring expressions reveals not only defects in the individual accounts provided by theorists from several different disciplines but also deep confusions about the roles that syntactic semantic and pragmatic factors play in accounting for these phenomena. The research we have undertaken is an attempt to sort out some of these confusions and to create the basis for a theoretical framework that can account for a variety of discourse phenomena in which all three factors of language use interact. The major premise on which our research depends is that the concepts necessary for an adequate understanding of the phenomena in question are not exclusively either syntactic or semantic or pragmatic. The next section of this paper defines two levels of discourse coherence and describes their roles in accounting for the use of singular definite noun phrases. To illustrate the integration of factors in explaining the uses of referring expressions their use on one of these levels . the local one is .
