摘要: An information retrieval system, including a learning and real-time classification methodology, is provided in accordance with the present invention. The system includes hierarchal analysis component that receives query processes probabilities associated N categories, each category having one or more topics, wherein an integer. interactive drives clarification dialog derived from categories topics. dialog, driven by rule-based policy, decision-theoretic considering costs of to focus results versus browsing larger lists, combinations rules employed when valuable determine at least facilitate
