This proceedings volume of the 5th AOISW orkshop is an opportunity for looking back at five years of organizing AOIS workshops. What did we achieve with the AOIS workshop series? Where were we five years ago, where are we now? Did our the me impact on the information systems field in the way that we had hoped for? AOIS workshops have taken place in Seattle, Heidelberg, Skholm, Austin, Montr´ eal, Interlaken, Toronto, Bologna, Melbourne, and Chicago, always in c- junction with a major conference on either multiagent systems in artificial - telligence (AI/MAS) or information systems (IS). We have tried to innovate in holding these workshops as biconference events (each year AOIS held two wo- shop events, one at an AI/MAS conference and one at an IS conference), as well as using the AOIS web site as a medium for communication among researchers. So, certainly, we have reached a wide audience of researchers around the world from both the AI/MAS and IS communities. But did we also manage to build up a dedicated AOIS community? Five years ago, we wrote: “Agent concepts could fundamentally alter the nature of information systems of the future, and how we build them, much like structured analysis, ER modeling, and Object-Orientation has precipitated fundamental changes in IS practice. ” Of course, a period of five years is too short for evaluating the success or failure of a new scientific paradigm. But still we may observe that while most IS conferences meanwhile list agents as one of their many preferred topics, agent-orientation is generally not considered to be a fundamental IS paradigm.
