Cognitive Artifacts for Intelligent Agents in MAS: Exploiting Relevant Information Residing  in Environments


Emiliano Lorini  /  Alessandro Ricci, Michele Piunti

Besides using languages and direct communication, humans
adopt various kind of artifacts as effective means to represent and share
knowledge, and finally support knowledge-based cooperation in complex
work environments. Similarly to the human case, we argue that an analo-
gous concept can be effective also in the context of cognitive multi-agent
systems (MAS). Based on previous work on artifact-based environment
and A&A conceptual framework, in this paper we investigate the use of
a special kind of artifacts, cognitive artifacts, as computational entities
designed to store, process and make available those information which is
relevant for agents to coordinate their cooperative and distributed activ-
ities. After introducing the main concepts, we discuss some of the practi-
cal benefits of the approach through an experiment based on CARTAGO
and Jason technologies, respectively a platform for developing artifact-
based environments for MAS and for programming cognitive BDI-based
agents, comparing different interaction styles for teams of goal-directed
agents engaged in distributed cooperative works
