....2. Agent Communication and Electronic Commerce This approach to agent communication gets its origins from KQML. This section gives an introduction of that part of KQML and other agent communication efforts that are pertinent to this work. 2. 1 Correlation with KQML The motivation for KQML [15][16] was to formalize a method by which agents can communicate effectively and efficiently. The message format supplies the agent with knowledge of which agent it is communicating to, a protocol for establishing dialogue, the language by which agents are communicating, terms by which other agents will ....

....communication that implements KQML semantics using Jini services. Two main focuses in specifying an implementation for agent communication languages are developing a standard suite of APIs that support message transfer and an infrastructure of services that support basic facilitation services [16]. The problem with this currently is that there are many different implementations that tend to deviate from the semantics. KOJAC standardizes an implementation by integrating a standard ACL into a known set of tools and services. By using the primitive structures and functions, other agent based ....

....6 Detailed Design The detailed design phase is intended to introduce additional detail for each architectural component of a system. In our case, this includes actor communication and actor behavior. To support this phase, we propose to adopt existing agent communication languages like FIPA ACL [35] or KQML [18] message transportation mechanisms and other concepts and tools. One possibility is to adopt extensions to UML [4] like AUML, the Agent Unified Modeling Language [3,38] proposed by the FIPA (Foundation for Physical Intelligent Agents) 19] and the OMG Agent Work group. We have also ....

....limited. For example, it does not address issues like cross platform migration of agents. In the area of Agent Communication Languages, two standards have been developed so far: FIPA ACL [4] and KQML [18] The purpose of ACLs in general is to facilitate interchange of information and knowledge [10]. A sample KQML message might look like this: ask one :sender joe :content (PRICE IBM price) receiver stock server :reply with ibm stock :language LPROLOG :ontology NYSE TICKS) The above message consists of a so called performative (ask one) a content part (price ibm price) and a ....

....versatility of natural languages which allow one to adapt to new situations. The current trend in ACL is the design of languages with a broad meaning and the use of protocols (i.e. rules of interpretation) for correctly understanding the meaning of the sentences in the context of a conversation [4]. 3 Examples Below are three examples in which the lack of a particular treatment of the interpretation of a representation by individuals prevents intelligibility. 3.1 Classes In a context related to knowledge formalisation, a user can express knowledge under the form of class hierarchies and ....

....themselves are based upon principles that have not been shown to be suitable for all classes of agent applications. Furthermore it has been suggested that the semantics are not as important to developers as the issues related to infrastructure such as naming services, matchmaking services etc [11]. Some of the issues with the ACL semantics are summarised below. Relationship to a theory of agency The FIPA ACL is intrinsically tied to a theory of agency which is not necessarily suitable for all agent applications. The Mariner team [12] have highlighted difficulties with an Agent based ....

.... the informative descriptions of Communicative Acts (CA) more useful [12] Irrelevance of rational Effects A sending agent cannot make any assumptions about the affect of a communicative act upon the receiver [12] Furthermore there is no guarantee that a Rational effect will come about at all [11], therefore rational effects are of no use in conformance testing. Difficulty in testing for compliance There is no obvious method of testing an agent for compliance with the semantics of the ACL, this is especially true for agents whose internal architecture does not correspond with that used ....
