Research on Intelligent Agents
Description
We are interested in the theory and practice of intelligent agents. We have applied our results to the following applications:
  • Information retrieval
  • Information dissemination over wide-area networks
  • Electronic commerce
  • Peer-to-Peer Computing
  • Business Process Modelling and Design
This work is done in the context of project DIET funded by the European Community under IST/FET.
