Abstract:
The collaboration between two intelligent agents can be greatly enhanced if a third agent, who has some understanding of the communication between the first two, intervenes with appropriate information or by acting helpfully. The behavior of the latter agent, which is quite common in human interaction, is called overhearing. We present an agent architecture modeling the overhearing behavior. In particular, we focus on overhearing based on ontological reasoning, that is, the overhearer semantically selects pieces of communication according to his own knowledge (ontologically organized) and goals. Internally, the overhearer is split in two sub-agents. One is the overhearing agent which, using a formal ontology, classifies the overheard communication. The other one is the suggester agent whose goal is to make appropriate suggestions at the appropriate time point. We present a formal language for the interaction of the two sub-agents.

A prototype of the architecture implemented using Jack Intelligent Agents is briefly described and preliminary experimental results are discussed.
