This paper describes the STAC resource, a corpus of multi-party chats annotated for discourse structure in the style of SDRT (Asher and Lascarides, 2003; Lascarides and Asher, 2009). The main goal of the STAC project is to study the discourse structure of multi-party dialogues in order to understand the linguistic strategies adopted by interlocutors to achieve their conversational goals, especi...

Prior to digital communications media, texts were primarily judged using hidden but assumed institutional practices (e.g., journal peer review processes, editorial mediation). Increasingly, digital communications media can make these previously invisible discursive practices visible in a persistent medium. Doing so transforms these discourses into texts where they are subject to: (1) a reader's...

Natural language is complex in structure, and contains considerable detail. All instances of language serve the purpose of making sense of experience and the intent of actors. Language conveys an actor’s personal reference to goals, responsibility, and values. In this paper we consider how actors from distinct perspectives communicate when they have share common goals and intent. We have observ...

Specifically, we examine how the process and product of metaphor production differ between ...

A number of systems have been developed for discourse generation that use hierarchical planning techniques to generate discourse plans [Appelt 1983,Cawsey 1993,Maybury 1992,Hovy 1991,Moore and Paris 1993]. These plan-based approaches provide various solutions to the problems of content and structure determination: what communicative acts should appear in a discourse plan, what are the relations...

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...
