The symposium entitled Acquiring (and Using) Linguistic (and World) Knowledge for Information Access gathered 20 some researchers and practitioners from corporations, research institutes, and academic institutions from far corners of the world. The subtitle was "Theory for systems; application for theories," and the aim was to find common ground between those who work on defining The American Association for Artificial Intelligence, in cooperation with Stanford University's Department of Computer Science, presented the 2002 Spring Symposium Series, held Monday through Wednesday, 25 to 27 March 2002, at Stanford University. The nine symposia were entitled (1) Acquiring (and Using) Linguistic (and World) Knowledge for Information Access; (2) Artificial Intelligence and Interactive Entertainment; (3) Collaborative Learning Agents; (4) Information Refinement and Revision for Decision Making: Modeling for Diagnostics, Prognostics, and Prediction; (5) Intelligent Distributed and Embedded Systems; (6) Logic-Based Program Synthesis: State of the Art and Future Trends; (7) Mining Answers from Texts and Knowledge Bases; (8) Safe Learning Agents; and (9) Sketch Understanding. The presentations ranged from new theories for computational modeling of brain information processing and applications of various types of multivariate statistical models to text categorization to name identification across documents and ontologybased search systems. The discussion centered on representational issues.
