....a timely and e#cient manner. The information channel is viewed as a means for transportation of information and not as an approach to supporting complex interactions at a higher level. Thus, a specific language or protocol for knowledge and information sharing needs to be provided, such as KQML [11, 19]. 3.4 Multiple Responses from Multiple Agents It is noted in [14] that, For DAI systems which use result sharing, the user may be confronted with a number of di#erent agent responses to the same demand. This could be extremely confusing, unless the DAI system facilitated her interactions ....

In addition, they must choose a set of acceptable message types. The messages can use any syntactic and semantic codes (KQML [3] and KIF [5] for example) The only requirement is that the agents also agree on a mapping from message type to response requirements. Finally, the target field can be used to indicate the intended recipient(s) of the message. It could be intended for a single team member, for some subset of ....

In particular, KQML assumes point to point message passing, possibly with the aid of facilitator agents [3]. Nonetheless, KQML performatives could be used for the content portions of our proposed communication scheme. KQML does not address the problems raised by having a single, low bandwidth communication channel. With only a single team present, a situation similar to the one considered here is ....

Among other, existing protocols for these three levels are KIF for content [GF92] KQML for message format [FMFM94] and COOL for coordination [Mat95] Planning Communicative Acts. Communication actions might alter the beliefs of other agents and therefore modify the external world. As a consequence, their execution is planned in the same way other actions are. The theory of communication as action is called ....

KQML is used as a language by application programs to interact with a network of intelligent agents and to share knowledge in support of cooperative problem solving [14].

....their expertise. In the subfield of agent research that focuses on agent architectures, various types of agents have been proposed that facilitate the communication process in a multi agent system. These agents, referred to with terms like facilitators, routers, mediators, brokers and so on (cf. [8]) act as intermediaries between communicating agents by providing services like the matchmaking between information producers and consumers. This denotes the act of referring agents in need of some piece of information to agents that might be able to provide it. As mentioned before, such ....

....the use of a centralized look up service. Although these distributed Web services can cooperate together to achieve a certain goal, they typically provide only predefined, limited functionalities. Another, more semantic approach, stems from earlier research in agent technology such as KQML [10]. Web services usually declare their capabilities (e.g. finding information about computers) and requirements (e.g. input format, communication mode) in a more or less expressive description language. Special purpose agents can then mediate services to users, by locating, matching and connecting ....

The interface exported by the communication objects implements KQML (Knowledge Query and Manipulation Language) performatives and their (possibly nested) argument lists [5]. KQML, being neutral to details of the content argument that varies with agents and services, makes it well suited for supporting the diverse uses of the UMDL. To facilitate the agent design, we provide an agent shell a C Agent class. The Agent class encapsulates the communication ....

Recently, several agent communication languages have been proposed in the literature, like for instance the language kqml [8]. However none of these communication languages have been given a fully formal account of their semantics [14] The main contribution of this paper is the introduction of a formal semantic theory for the exchange of information in multi agent systems.

....this paper presents a rst formal semantic account of the exchange of information in multi agent systems. This semantics, we believe, provides a general basis for the semantics of agent communication languages in general as introduced in arti cial intelligence, like for instance the language kqml [8]. Other approaches that relate to our programming language include the work of R ety on distributed concurrent constraint programming [12] One of the differences with our approach is that in this framework distributed processes do not share any variables. In particular, communication between ....
