TAILIEUCHUNG - Báo cáo khoa học: "Event-building through Role-filling and Anaphora Resolution"

In this study we map out a way to build event representations incrementally, using information which may be widely distributed across a discourse. An enhanced Discourse Representation (Kamp, 1981) provides the vehicle both for carrying open event roles through the discourse until they can be instantiated by NPs, and for resolving the reference of these otherwise problematic NPs by binding them to the event roles. INTRODUCTION The computational linguistics literature includes a wide variety of ideas about how to represent events in as much detail as is required for reasoning about their implications. . | Event-building through Role-filling and Anaphora Resolution Greg Whittemore Electronic Data Systems Corp. 5951 Jefferson Street .

An enhanced Discourse Representation Kamp 1981 provides the vehicle both for carrying open event roles through the discourse until they can be instantiated by NPs and for resolving the reference of these otherwise problematic NPs by binding them to the event roles. INTRODUCTION The computational linguistics literature includes a wide variety of ideas about how to represent events in as much detail as is required for reasoning about their implications. Less has been written about how to use information in text to incrementally build those event representations as discourse progresses especially when the identification of event participants and other details is dispersed across a number of structures. We will be concerned here with providing a representational framework for this incremental event-building and with using that representation to examine the ways in which reference to the internal structure of events contributes to discourse cohesion. That is we will be interested both in the process of gleaning fully-specified event descriptions from continuous text and in showing how individual elements of an event s internal structure can behave anaphorically. Examples of the kinds of linkages that must be dealt with in building representations of events from text follow la He was believed to be a liar. b We promised him to be truthful. c He tried to keep his mouth shut. 2a Joe gave Pete a book to read. b Joe gave Pete a book to .
