Pragmatic modeling: toward a robust natural language interface

One of the most important ways in which an information‐provider can assimilate an information‐seeking dialogue is by inferring the underlying task‐related plan motivating the information‐seeker's queries. This paper presents a strategy for hypothesizing and tracking the changing task‐level goals of an information‐seeker and building a model of his task‐related plan as the dialogue progresses.
