This book constitutes the thoroughly refereed post-proceedings of the 13th Agent-Oriented
Software Engineering (AOSE) workshop held at the 11th International Conference on Autonomous
Agents and Multiagent Systems AAMAS 2012 in Valencia Spain in June 2012. This volume
presents 9 thoroughly revised papers selected from 24 submissions as well as two invited
articles by leading researchers in the field. The papers cover a broad range of topics related
to software engineering of agent-based systems with particular attention to the integration of
concepts and techniques from multi-agent systems with recent programming languages platforms
and established software engineering methodologies.
