This book constitutes the thoroughly refereed post-proceedings of the 29th Annual German Conference on Artificial Intelligence, KI 2006, held in Bremen, Germany, in June 2006 - co-located with RoboCup 2006, the innovative robot soccer world championship, and with ACTUATOR 2006, the 10th International Conference on New Actuators.
The 29 revised full papers presented together with 2 invited contributions were carefully reviewed and selected from 112 submissions. The papers are organized in topical sections on cognition and emotion, semantic Web, analogy, natural language, reasoning, ontologies, spatio-temporal reasoning, machine learning, spatial reasoning, robot learning, classical AI problems, and agents. The book is completed with the extended abstracts of 8 lectures - especially invited for the public symposium `50 Years AI' held after the regular conference sessions.
