报告摘要（ABSTRACT）：
This talk describes the outcome of a successful Japanese national project conducted under the “Research-for-the-Future” program and led by the speaker as the principal investigator. The system is based on the following three original principles: (a) Dialogue Management based on both User and System Modeling (by introducing a novel type of interacting automaton), (b) Use of “Key Concepts” in information retrieval (including processing of polysemy, homonymy, and unknown words), and (c) Optimization of Retrieval Performance through Relevance Score Estimation (by introducing a measure of relevance of search results based on users’ judgments. The advantages of these novel principles have been demonstrated by a pilot system.
