A Constraint-Based Approach for Cooperative Information-Seeking Dialogue

By Yan Qu and Nancy Green


We present a dialogue generation model, implemented in the COMIX prototype information system, which uses a Constraint -Based Problem-Solver (CBPS) to support cooperative mixed-initiative information -seeking dialogue. Use of the CBPS enables a dialogue system to 1) incrementally interleave query construction with solution construction 2) immediately detect under-constrained and over-constrained information requests, and 3) provide cooperative responses when these types of problems are detected. We also present a system evaluation investigating how well COMIX handles dialogues with over-constrained requests
