The results of this grant cover a wide range of issues in knowledge representation, natural language and learning. The early years of the grant primarily center on the development of connectionist approach to representation and language. At the same time, the development of plan-based models of dialog by the PI was setting the ground for a major push in the area of natural language dialog. The principal objective of the dialog project was to develop a system for representing and reasoning about the discourse context in extended man-machine dialogs. The focus areas included the development of a model that captures the structure of natural-language dialog, the development of a general knowledge representation for capturing a wide range of natural language semantics, and the development of a general, error-tolerant parser and semantic interpreter for English that can be guided by discourse information. Specifically, we developed a model of discourse plans that includes actions such as introducing a new topic, as well as the actions of clarifying, correction or acknowledging parts of the previous dialog. We also explored how the traditional language components, i.e. parsing, semantic interpretation and discourse processing, could be adapted to the dialog scenarios.
