Halpern, IBM Almaden Research Center Tutorial SP4 (Sunday, 2 pm - 6 pm, July 11) Distributed Artificial Intelligence Tools Edmund H. Durfee, University of Michigan; and Katia P. Sycara, Carnegie Mellon University This tutorial will thoroughly survey problems, techniques and applications in contemporary DAI, in preparation for building DAI systems or as background for doing research to advance the state of DAI practice. Particular emphasis will be given to DAI tools and to methodologies for building and evaluating DAI systems. Real-world DAI applications, such as heterogeneous intelligent information systems and coordinated intelligent vehicles, are only beginning to emerge. We hope, through this tutorial, to speed this process by introducing DAI algorithms and paradigms to attendees in practical, rather than only theoretical, terms. Prerequisite Knowledge: The tutorial presumes knowledge of AI at the level of an introductory course, and familiarity with such general concepts as object-oriented systems, planning, heuristic search, knowledge-based systems, reasoning under uncertainty, and so on. Edmund H. Durfee received his Ph.D. degree in computer and information science from the University of Massachusetts, Amherst. He is currently an Assistant Professor in the Dept. of Electrical Engineering and Computer Science at the University of Michigan, where his interests are in distributed AI, planning, blackboard systems, and real-time problem solving. He is the author of Coordination of Distributed Problem Solvers, and is also a 1991 recipient of a Presidential Young Investigator award from the National Science Foundation. Katia P. Sycara is a Research Scientist in the School of Computer Science at Carnegie Mellon University. She is also the Director of the Laboratory for Enterprise Integration, where she is conducting research in investigating and integrating decision making across the manufacturing product life cycle. She received her Ph.D. in Computer Science from Georgia Institute of Technology, and is area editor for Group Decision and Negotiation journal. ------------------------------ From: potdevin@loria.fr (Potdevin Ralph) Subject: Info needed: object/frame/actor language Date: 9 Apr 93 11:09:36 GMT Hi Everybody, My research is concentrating on designing a general document recognition system, using a blackboard/semantic network/distributed agents architecture (all of this in the same system: how fun!). (This architecture is inspired of ideas by Douglas Hofstadter and his team at CRCC, Indiana University.) For this reason, I'm seeking, if it exists, a language which could be well adapted to these 3 components. There is need for static as well as dynamic knowledge representation (conceptual network vs. ~blackboard), and something like actors or objects able to act asynchronously in a pseudo-parallel manner, and able to send messages to each other and to interact through the blackboard. And more, I'd like a language with inheritance (possibly multiple), and classes (and possibly metaclasses).... So if any of you know of languages that could fit these requirements, even partially, I'd like them to send me a mail note. If many people answer and if the topic raises interest, I'll be happy to post a digest of the replies I hope to get. All replies and comments are welcome.
