This book constitutes the thoroughly refereed post-proceedings of the Second International Workshop on Modeling and Retrieval of Context, MRC 2005, held in Edinburgh, UK in July/August 2005, as associated event of the 19th International Joint Conference on Artificial Intelligence, IJCAI 2005.

The 9 revised full papers presented were carefully selected and include extended versions of some of the papers presented at the MRC 2005 workshop. A major goal of the workshop was to study, understand, and explore the handling of context in IT applications. The papers illustrate the state of the art of context modeling and elicitation as well as identification and application of context in different application scenarios.
