Dissertation Abstract:
We have developed a framework for controlling utterance generation in multi-party human-computer dialogue. This process takes place in four stages: (i) the rhetorical structure for the dialogue is computed, by using an emulation of SDRT ('Segmented Discourse Representation Theory'); (ii) this structure is used for computing speakers' commitments; these commitments are used for driving the process of adjusting the illocutionary force degree of the utterances; (iii) the commitments are filtered and placed in a stack for each speaker; these stacks are used for performing semantic ellipses; (iv) the discourse structure drives the choice of concessive connectors (mais, quand même, pourtant and bien que) between utterances; to do this, the utterances are ordered from an argumentative viewpoint.
