Classical SDRT (Asher and Lascarides, 2003) discussed
essential features of dialogue like adjacency
pairs or corrections and up-dating. Recent work in
SDRT (Asher, 2002, 2005) aims at the description
of natural dialogue. <br>We use this work to model
situated communication, i.e. dialogue, in which
sub-sentential utterances and gestures (pointing and
grasping) are used as conventional modes of communication.<br>
We show that in addition to cognitive
modelling in SDRT, capturing mental states
and speech-act related goals, special postulates are
needed to extract meaning out of contexts. Gestural
meaning anchors Discourse Referents in contextually
given domains. Both sorts of meaning are fused
with the meaning of fragments to get at fully developed
dialogue moves. This task accomplished, the
standard SDRT machinery, tagged SDRSs, rhetorical
relations, the up-date mechanism, and the Maximize
Discourse Coherence constraint generate coherent
structures. In sum, meanings from different
verbal and non-verbal sources are assembled using
extended SDRT to form coherent wholes.
