The Multi-Agent Systems (MAS) group at IIIA-CSIC carries out scientific research of excellence in areas that are central to autonomous agents and multi-agent systems: computational models of negotiation, control and organisation, trust and reputation, optimisation, semantics, and recommender systems. It positions itself at the intersection of CSIC's global areas SOCIETY and MATTER through interdisciplinary research of high socio-economic impact. The goals of the group are governed by an approach to AI focused on human beings, developing computer systems that are aligned with the ethical and social values of the communities that use them, empowering people in the interactions mediated by these systems, respecting and fostering diversity, and exploring new forms of collaboration.
Head of the Group: Marco Schorlemmer
