Pragmatics And AAC Approaches To Conversational Goals

چکیده
The modelling of pragmatic features of natural conversation to help AAC users achieve a range of social conversational goals is considered in relation to the development of an AAC system based on text pre-storage and retrieval. Problems facing designers of AAC systems are highlighted in the hope that insights from NLP may contribute to solutions. 1 Conversational goals People have a variety of implicit and explicit goals when engaging in conversation, among which a broad distinction between social goals and goals concerned with "getting things done" can be discerned. For example, Cheepen's (Cheepen, 1988) distinction between transactional goals and interactional goals has considerable overlap with Hobbs and Evans' (Hobbs and Evans, 1980) ideational and interper-

A Pragmatics-Based Approach to Ellipsis Resolution
Intersentential elliptical utterances occur frequently during information-seeking dialogs in task domains. This paper presents a pragmatics-based framework for interpreting such utterances. Discourse expectations and focusing heuristics are used to facilitate recognition of an information-seeker's intent in uttering an elliptical fragment. The ellipsis is comprehended by identifying both the as...
متن کاملEmbedded Implicatures and Optimality Theoretic Pragmatics
In a recent paper, Chierchia (2004) distinguishes global and local approaches to conversational implicatures and claims that several puzzles concerning implicatures in complex sentences can best be explained by a local approach. This conflicts with the Neo-Gricean view which is global in nature. I will argue that both approaches can coexist in optimality theoretic pragmatics where the proper pl...

Pragmatics moves away from the word level and sentence level study of language towards the study of language in real-world context and at discourse level whereby two or more participants take part in conversation. There are moments when the speaker explicitly says something but the listener may have other interpretations and inferences from their statements. The aim of this study was to demonst...
متن کاملAutomatic generation of conversational utterances and narrative for Augmentative and Alternative Communication: a prototype system
We detail the design, development and evaluation of Augmentative and Alternative Communication (AAC) software which encourages rapid conversational interaction. The system uses Natural Language Generation (NLG) technology to automatically generate conversational utterances from a domain knowledge base modelled from content suggested by a small AAC user group. Findings from this work are present...
