....formulation is an architecture for possible organisations of an interactive system where control is either centralised to an umpire, or distributed to individual players, or both. We exemplify the architecture by showing how to formulate interactions resulting from agent interaction protocols [Fou97].

....relate this to existing literature on agent communication languages. 2 Imperatives and agent communication Knowledge level [16] communication between agents through speech act based [2, 20] agent communication languages (ACLs) is both an active area of research [23, 19] and of standardisation [8, 7]. These languages typically include indicatives (or assertions) such as tell (KQML) and inform (FIPA) for example, It s raining . Queries or questions are also common (i.e. interrogatives) such as ask if (KQML) and query if (FIPA) for example, Is it raining . In addition to these, ....

.... For example, one agent offers a service to another, which may be responded to with acceptance, rejection or silence (cf. Barbuceanu and Fox [3] This extension of an agent communication language to capture typical conversations between agents is the approach taken by the FIPA specification [8], and it is the specification of imperatives within FIPA that is returned to in section 5. The grounding of agent communication languages in such formal models is essential to ensure that the meaning of communicative acts are clear to those designing agents for practical applications. Without ....

....they specify the form of a conversation, but leave open the content. Two policies are illustrated in Figures 1 and 2. Bradshaw and others suggest that these conversation policies can be either the result of emergent behavior (in the case of intelligent agents) or the result of off line design [1, 6]. In either case, the agent must behave in conformance with # This research was supported in part by the Information Technology Promotion Agency, Japan, as part of the Industrial Science and TechnologyFrontier Program, New Models for Software Architecture sponsored by NEDO (New Energy and ....

....to notify the other agent should he change his mind or discover a problem with the REQUEST. By communicating his PWAG the agent is already treating the agent receiving the REQUEST as a team member [11] This meaning of REQUEST differs from the semantics of the REQUEST in the FIPA ACL specification [6], for which the feasibility preconditions are based only on the intentions of the requesting agent. While this is sufficient to communicate the content of the REQUEST, it is not a strong enough commitment to begin forming a team. For example, should the requesting agent drop the intention behind ....

....divided from other aspects of system functionality. In the specification provided in this paper, these aspects can be integrated. Thirdly, in undertaking the previous aims, we draw out guidelines that may be applied more generally to the specification of other protocols for agent communication [1, 4, 6]. We begin in the next section by considering what is required in the general case of such a protocol specification. This overview provides an indicationof how other specifications might be developed and serves to give structure to the specification of the Agentis protocols, which is organised as ....

....5 and 6 we de 3 fine our approach to introspection and communication in agents, respectively. In section 7 we illustrate the framework by means of an example. In section 8 we consider some communication performatives from exisiting agents communication languages, in particular the FIPA ACL [12] and show how to express them and their semantics in our framework, in terms of the basic primitives tell and ask. In section 9 we conclude and discuss future work. This paper is a revised and extended version of [10] 2. Preliminaries 2.1. Basic definitions Definition 1. A logic program is a ....

Existing communication languages, e.g. KQML [11] and FIPA ACL (Agent Communication Language) [12], include additional performatives, such as ask if, ask one, ask all, deny, achieve and unachieve in KQML and inform, query if, request, request whenever, propose in FIPA ACL, to mention a few. In this section we will show how some of the performatives in FIPA ACL can be expressed via definitions ....
