What are Agents? ...Software entities that assist people and act on their behalf ...Software “robots” Proactive detect changes in their environment and react to those in a timely manner by answering to events and initiating actions Traditional Software Object Goal-driven have a purpose and act in accordance with that purpose until it is fulfilled Behavior State Agent Technology Communicative able to interact and communicate with users and other agents Autonomous can have control over their own actions and be able to work and launch actions independent of the user or other actors Learning have the ability to learn from experiences in their environment
Simple Agent Example Agent, find me the book “War and Peace,” and I need it tomorrow Amazon 2 Days $18.50 Barnes and Nobel 1 Day $21.75 Borders NA ... Does the agent understand buying books? Form a plan to buy the book Execute the plan Order the book B. Dalton 1 Day $20.25 Learn for next time

Current situation • Problem • Field Work Proposals (FWPs) submitted to DOE are in paper books • Weeks and thousands of dollars are spend in collating, copying, binding, and shipping these books • The books provide very limited query and search capability • Approach • Developed an FWP “ontology” for several national laboratories • Pioneered use of the Extended Markup Language (XML) as a means of storing, querying, and presenting FWP information. • Simple data storage technology • Very low costs to the labs, integration work done by CME team • Very well received article at XML’98, InForum’99, InterLab’99.
