  2. Personal Background Computer scientist who values insights from studies of social systems and organizations • B.Tech., IIT-Delhi, CS&E; Ph.D., U Texas, Austin • Professor, Computer Science, NCSU • EIC Emeritus, IEEE Internet Computing • MEB, J. Autonomous Agents & MultiAgent Systems; J. Web Semantics • Cochair, International Joint Conference on Autonomous Agents & MultiAgent Systems, 2005 • NSF support: DST + ITR (past IDM)

  3. Referral Systems and Networks • KM going beyond document management • Developed a prototype adaptive referral system for use by people, 1998-2003 • Studied effectiveness for searching experts • Studied emergent structural properties contrasting with static studies of Web structure and recommender systems, 1999-present • Quality inversely related with clustering • Distributions of degree and authority under various behaviors • Emergence of communities

  4. Architectural Power of SNs • SNs are the right metaphor for dealing with open systems • Changing membership and relationships • Autonomous parties of unknown trustworthiness • SNs provide meaning, assessment of possibilities, basis for trust • SNs support service selection and system configuration • Computing challenge: automate the appropriate parts to improve productivity while still leaving a window for human insight
