Extending a Formal and Computational Model of Rhetorical Structure Theory with Intentional Structures la Grosz and Sidner

نویسنده

  • Daniel Marcu
چکیده

In the last decade, members of the computational linguistics community have adopted a perspective on discourse based primarily on either Rhetorical Structure Theory or Grosz and Sidner’s Theory. However, only recently, researchers have started to investigate the relationship between the two perspectives. In this paper, we use Moser and Moore’s (1996) work as a departure point for extending Marcu’s formalization of RST (1996). The result is a first-order axiomatization of the mathematical properties of text structures and of the relationship between the structure of text and intentions. The axiomatization enables one to use intentions for reducing the ambiguity of discourse and the structure of discourse for deriving intentional inferences.

A Collaborative Planning Model of Intentional Structure

An agent's ability to understand an utterance depends upon its ability to relate that utterance to the preceding discourse. The agent must determine whether the utterance begins a new segment of the discourse, completes the current segment, or contributes to it. The intentional structure of the discourse, comprised of discourse segment purposes and their interrelationships, plays a central role...

Toward a Synthesis of Two Accounts of Discourse Structure

Among researchers interested in computational models of discourse, there has been a long-standing debate between proponents of approaches based on domain-independent rhetorical relations, and those who subscribe to approaches based on intentionality. In this paper, we argue that the main theories representing these two approaches, RST (Mann and Thompson 1988) and G&S (Grosz and Sidner 1986), ma...

Planning Text for Advisory Dialogues

Explanation is an interactive process requiring a dialogue between advice-giver and advice-seeker. In this paper, we argue that in order to participate in a dialogue with its users, a generation system must be capable of reasoning about its own utterances and therefore must maintain a rich representation of the responses it produces. We present a text planner that constructs a detailed text pla...
