The seventh German Conference on Multi-Agent System Technologies (MATES 2009) took place in Hamburg, Germany, during September 9-11, 2009, and was colocated with the tenth International Workshop on Computational Logic in Multi-Agent Systems (CLIMA X) and the Fifth International Workshop on Modelling of Objects, Components, and Agents (MOCA 2009). MATES 2009 wasorganizedby the German"Gesellschaft für Informatik" (GI) Special Interest Groups on "Distributed Arti?cial Intelligence" and "Communication and D- tributed Systems" in cooperation with the Steering Committee of MATES. One main aim of the MATES conference series consists in bringing together researchers from around the world and providing a fruitful discussion basis for exchanging ideas and sharing the newest scienti?c results. Since its inception in 2003, MATES has been colocated with mainstream software engineering conf- ences like the Net. ObjectDays as well as with the German Arti?cial Intelligence Conference (KI) and has thus strived to address the full range of agent research topics ranging from practical applications and tools for agent technology to the theoreticalfoundations of multi-agentsystems. In additionto the broadrange of topics covered by MATES, in recent years special areas of interest (hot topics) within the ?eld of multi-agent systems have also been identi?ed and have in- enced the conference editions. In 2009 the focus was laid on complex, adaptive systems and phenomena of self-organization.

This book constitutes the refereed proceedings of the 7th German Conference on Multiagent Systems Technologies, MATES 2009, held in Hamburg, Germany in September 2009 - colocated with the 10th International Workshop on Computational Logic in Multi-Agent Systems (CLIMA X) and the 5th International Workshop on Modelling of Objects, Components, and Agents (MOCA 2009).
The 14 revised full papers, 10 short papers, and 5 exhibition papers presented together with one invited talk were carefully reviewed and selected from 44 submissions. The papers present and discuss the latest advances of research and development in the area of autonomous agents and multiagent systems ranging from theoretical and methodological issues to applications in various fields.
