Intentionalist approaches to dialogue
Characteristic of intentionalist approaches:The chief explanatory notion is that of a certain type of mental state of adiscourse participant – the intention she has.
Intentions have a disputed ontological status: Are they reducible to other (mental)states or are they states in their own rights?
E.g., one could try to do this reduction:1. S intends to A just in case2. S desires that G and3. S believes that Aing leads to G(obvious problems)

Approach under consideration:Grosz, B.J. & Sidner, C.L., Computational Linguistics, Vol. 12 (3), 1986:Attention, Intention, and the Structure of Discourse
As we develop it, the theory of discourse structure will be seen to beintimately connected with two nonlinguistic notions: intention and attention.

So there are two goals for explication: processing and structure.

Why should one be interested in a theory of discourse structure?

Intentionalist approaches to dialogue
Discourse structure
Why should one be interested in a theory of discourse structure? There is evidencethat antecedents in discourse are decreasingly well accessible for anaphoric reference depending on diverse factors.

Why should one be interested in a theory of discourse structure? There is evidencethat antecedents in discourse are decreasingly well accessible for anaphoric reference depending on diverse factors. Current theories of anaphoric resolution (e.g., standard DRT or FCS) are bad in capturing this.

Current theories of anaphoric resolution (e.g., standard DRT or FCS) are bad in capturing this.One suggestion (Muskens, van Benthem and Visser (1997)) could be to strengthenstandard dynamic semantics by complementing them with a theory of discoursestructure.

Discourse structure • the structure of the actual sequence of utterances
Just as the words in a single sentence form constituent phrases, theutterances in a discourse are naturally aggregated into discourse segments.The utterances in a segment, like the words in a phrase, serve particularroles with respect to that segment.

[T]he range of intentions that can serve as discourse, or discourse segment,purposes is open-ended …, much like the range of intentions that underliemore general purposeful action. Thus, a theory of discourse structure cannotdepend on choosing the DP/DSPs from a fixed list …, nor on the particularsof individual intentions. … In this paper, we distinguish between thedetermination of the DSP and the recognition of it. We use the term determination to refer to a semantic-like notion, namely the completespecification of what is intended by whom; we use the term recognition torefer to a processing notion, namely, the processing that leads a discourseparticipant to identify what the intention is.

An analysis in the spirit of G&S (though not authentical)
The solutionfor DSP3 is notvery plausible. Yet,DSP3 DOM DSP4.Hence, DSP4should onlycontribute to DSP3.On the other hand,DSP4 SP DSP6, sothey must be DSs.

Discourse structure
Our main thesis is that the structure of any discourse is a composite of threedistinct but interacting components:•the structure of the actual sequence of utterances in the discourse;•a structure of intentions;•an attentional state.

Intentionalist approaches to dialogue
Our main thesis is that the structure of any discourse is a composite of threedistinct but interacting components:•the structure of the actual sequence of utterances in the discourse;•a structure of intentions;•an attentional state.
G&S 176
The results of the processing, the completed structures, differ in some respect:• the structure of the sequences is built up during discourse and exists in full size only in the end of it;• similarly, the structure of intentions is constructed successively;
Discourse structure • interaction between structures

Approach under consideration:Grosz, B.J. & Sidner, C.L., Computational Linguistics, Vol. 12 (3), 1986:Attention, Intention, and the Structure of Discourse
As we develop it, the theory of discourse structure will be seen to beintimately connected with two nonlinguistic notions: intention and attention.Attention is an essential factor in explicating the processing of utterancesin discourse. Intentions play a primary role in explaining discoursestructure, defining discourse coherence, and providing a coherentconceptualization of the term "discourse" itself.
G&S 175
So there are two goals for explication: processing and structure.

Approach under consideration:Grosz, B.J. & Sidner, C.L., Computational Linguistics, Vol. 12 (3), 1986:Attention, Intention, and the Structure of Discourse
As we develop it, the theory of discourse structure will be seen to beintimately connected with two nonlinguistic notions: intention and attention.Attention is an essential factor in explicating the processing of utterancesin discourse. Intentions play a primary role in explaining discoursestructure, defining discourse coherence, and providing a coherentconceptualization of the term "discourse" itself.
G&S 175
So there are two goals for explication: processing and structure.
