1. DARPA CoABS Workshop Las Vegas, NV. Final Group 1 (TIE) Briefing Coordinator: Katia Sycara January 29, 1999

2. LV 1999: Group 1 Briefing Katia Sycara2 Group Results 1. Participants in each TIE got together to resolve technical issues –There will be 3 TIEs conceptually connected through a story. –consensus –commitment 2. Participants discussed –Visualization of multi-agent interactions in the TIEs –Functionality of agents –Agent activity –Debugging/history

3. LV 1999: Group 1 Briefing Katia Sycara3 Group Results (continued) 3. Interaction of TIEs and GRID 4. Scientific Claims 5. Procedural Issues

4. LV 1999: Group 1 Briefing Katia Sycara4 GRID 1. Agreed with current view of GRID design of GITI/ISX of bottom up 2. Services eg. Interoperability agent RETSINA matchmaker OAA facilitator

5. LV 1999: Group 1 Briefing Katia Sycara5 GRID (continued) Other Useful Services for TIEs translation visualization support for different types of simulators networking infrastructure language/tools for best use of GRID services service description languages

6. LV 1999: Group 1 Briefing Katia Sycara6 Summary of Scientific Claims TIE 1 - “Helo Evac” Key Questions 1. Can multi-agents be programmed at the team-level? (Team-Oriented Programming) 2. What are the key requirements for ACLs in team setting? 3. What are the key requirements for distributed monitoring & diagnosis to provide (guaranteed) robustness?

7. LV 1999: Group 1 Briefing Katia Sycara7 Team-Oriented Programming (TOP) Short-Term Goals (March) Can TIE team be programmed by: –Organization Hierarchy –Team Procedures –Current team goals and plans –Automated coordination via TEAMCORE? Long-Term Goals Extract general principles of “TOP” and build tools to facilitate “TOP”

8. LV 1999: Group 1 Briefing Katia Sycara8 Distributed Monitoring, Diagnosis & Recovery Short-Term Goals (March) Explore appropriateness of existing techniques in TEAMCORE for distributed monitoring, diagnosis & recovery Build primitives for TEAMCORE agents to monitor domain-level agents Compile logs of failures Long-Term Goals Extract general principles from compiled logs, add to existing TEAMCORE techniques

9. LV 1999: Group 1 Briefing Katia Sycara9 ACLs for TEAMs Short-Term Goals (March) Explore shortcomings of existing ACLs for TEAMWORK Explore interoperation of OAA (Quickset) & TEAMCORE (KQML) Long-Term Investigate efficiency of semantics of ACL (particularly for teamwork) Development of semantic interpretation bridge between TEAMCORE and OAA

10. LV 1999: Group 1 Briefing Katia Sycara10 Scientific Claims Technical Challenges TIE 2 1. Coherent Communication –Webtrader brokers information sources Adriadne dynamically incorporates request “Address in Kuwait for conference attendees” –Multiple translators glued together speech (MMM)  ML Menus 2. Control –Planner controls multiple simulated physical agents –Planner responds to outside events –Posting goals 3. Human in the loop

11. LV 1999: Group 1 Briefing Katia Sycara11 1. Coherent communication of meaning between two heterogeneous MAS 2. Functional substitutability of agents 3. “Agentification” of legacy systems 4. Adaptivity at different levels: –Interfaces –MAS organization –Single Agent 5. Collaboration –human-human –human-agent –MAS Scientific Claims Technical Challenges TIE 3

12. LV 1999: Group 1 Briefing Katia Sycara12 1. Coherent Communication of Meaning Short-Term Goals –Structure of interop agent –Protocols of interop agent Long-Term Goals –Interoperation services for the GRID? –ACL’s for the GRID 2. Functional Agent Substitutability Short-Term Goals –Provide languages and protocols for capability advertisement Long-Term Goals –Mechanisms for resolving mismatches of substitutable agent tasking and results Scientific Claims - TIE 3

13. LV 1999: Group 1 Briefing Katia Sycara13 3. “Agentification” of legacy systems Short-Term Goals –Providing wrapping mechanisms Long-Term Goals –Explore different mechanisms for agentification 4. Adaptivity/Robustness Short-Term Goals –Adaptive interface to user resources –Organizational adaptivity through middle agents Long-Term Goals –Explore additional mechanisms for organizational adaptivity Scientific Claims - TIE 3 (continued)

14. LV 1999: Group 1 Briefing Katia Sycara14 5. Collaboration –Human-Agent Short-Term Goals Giving tasks to agents Long-Term Goals Principles for functional role allocation between human and agent –MAS Short-Term Goals dynamic team formation Long-Term Goals tradeoffs of different organizational structures (eg. Teams, hierarchies, heterarchies) Scientific Claims - TIE 3 (continued)

15. LV 1999: Group 1 Briefing Katia Sycara15 Procedural Issues 1. Increase frequency of telecons to 1 per week 2. Build Ties at GITI/ISX –set and commit to a date –install components –meet to rehearse –clarify audience
