We conducted an empirical analysis into the relation between control and discourse structure. We applied control criteria to four dialogues and identified 3 levels of discourse structure. We investigated the mechanism for changing control between these structures and found that utterance type and not cue words predicted shifts of control. Participants used certain types of signals when discours...

We describe a data-driven approach to building interpretable discourse structures for appointment scheduling dialogues. We represent discourse structures as headed trees and model them with probabilistic head-driven parsing techniques. We show that dialogue-based features regarding turn-taking and domain specific goals have a large positive impact on performance. Our best model achieves an f sc...

During content planning, a typical discourse generation system receives as input a library of facts and selects facts to include as the content for utterances. However, storytellers do not need to be completely constrained by a set of facts and instead can invent facts which support the storytellers goals, subsequently constructing the storyworld around those facts. We present a discourse-drive...

I'his paper describes GENIE, an object-oriented architecture that generates text with the intent of extending user expertise in interactive environments. Such environments present three interesting goals. First, to provide information within the task at hand. Second to both respond to a user's task related question and simultaneously extend their knowledge. Third, to do this in a manner that is...

We present an approach to taking the initiative to provide unrequested but relevant information in responses to Yes-No questions. In our model, stimulus conditions represent types of discourse contexts in which a speaker would be motivated to provide unrequested information. Stimulus conditions can be thought of as situational triggers which give rise to new speaker goals, and which are the com...

In this position paper, we argue Ibr the need for a generation system to represent communicative goals (i.e., goals that express the speaker's intent to aflect the bearer's mental attitudes), at least if certain tasks are to be achieved. We lurther argue that, wlfile rhetorical relations might be recoverable t tom other Iactors, they appear to be a useful level of abstraction to maintain about ...

In fact, although this type institutional discourse, considered a subject forensic has so far been examined by many foreign linguists lawyers, it not yet studied Uzbek linguistics based pragmalinguistic approach.
