1 TALARIS - Natural Language Processing: representation, inference and semantics

The grounding process relies on the evidence that speakers give about their understanding (Clark &Schaefer,89). However in existing formal models of grounding (Cahn, 92; Cahn & Brennan, 99; Traum, 99) evidence of understanding is assumed to be symmetrically and synchronously shared by the speakers. We propose a formal model, based on (Cahn, 92), that removes these simplifications; we do so by distinguishing the phase of interpretation from the phase of evidence extraction and introducing the notion of floating contributions.
