In this paper we present the communication architecture of the DALI Logic Programming Agent-Oriented language and we discuss its semantics. We have designed a meta-level where the user can specify, via the distinguished tell/told primitives, constraints on communication or even a new protocol. Moreover, the user can define meta-rules for filtering and/or(More)
Interaction is an important aspect of Multi-agent systems: agents exchange messages, assertions, queries. This, depending on the context and on the application, can be either in order to improve their knowledge, or to reach their goals, or to organize useful cooperation and coordination strategies. In open systems the agents, though possibly based upon(More)
In this paper we describe the communication architecture of the DALI Logic Programming Agent-Oriented language. We have implemented the relevant FIPA compliant primitives, plus others which we believe to be suitable in a logic setting. We have designed a meta-level where: on the one hand the user can specify, via two distinguished primitives tell/told,(More)
valutazione dell'interlocutore come ad esempio la fiducia, intesa come forma di conoscenza sociale basata su vari fat-tori, fra cui le interazioni avvenute nel passato.
