Competing agents in agent-mediated institutions

Social processes and agent interaction always take place in a specific context. A school of thought in social studies analyses them in the framework of institutions. We present in this paper the notion ofagentmediated institutions and show how it is relevant for multi-agent systems (MAS) in general and, more specifically, for MAS that include human agents and software agents involved in socioeconomic interactions. We show how the social interactions of human and software agents taking place in the Cohabited Mixed-Reality Information Spaces (COMRIS) project can be described as such an institution, the Conference Centre institution.
