一个基于XML的Agent通信框架 总被引:8,自引:0,他引:8
Agent通信是多Agnet系统的核心活动之一,是Agent相互协调、合作、竞争和完成任务的基础。Agent通信语言为此提供了一种高层次、灵活、通用的通信模式。在KQML和FIPA-ACL的基础上提出通用Agent通信语言的概念,阐述构建通用ACL的重要性和可行性,深入讨论一个基于XML的Agent通信框架,最后给出实例。 相似文献

目前主流的主体通信语言FIPA ACL对于形成团队协作求解存在通信原语支持不充分的问题.首先指出基于全责提议通信原语的FIPA ACL不能充分支持团队协作的原因,进而明确区分全责提议与联合提议,引入语义成分扩展定义了联合提议.通过以联合提议原语形成的团队性质定理之验证,从理论上使团队在以联合提议形式进行联合意图交流时,团队主体间的协作能力得到改进. 相似文献

团队是动态不可预测性环境下协作问题求解的有效方式,联合意图是团队联合求解的关键.因此,主体在团队活动中如何采用言语动作形成、维护、解除联合意图,是一个值得研究的重要问题.旨在设计一种基于主体通信语言FIPA(foundation forintelligent physical Agent)ACL(Agent communication language)的多主体团队交互协议.首先,分析了现有FIPA ACL支持团队联合求解的充分性问题.在概念上明确区分了联合请求与委托请求,指出委托请求言语动作不能充分支持团队协作.并扩展定义了联合请求,讨论了相关定理.然后,基于联合请求动作,提出一种主体团队交互协议,并给出了协议的形式化语义,最后讨论了协议的实际应用.区别于现有的基本动作请求协议、合同网协议以及拍卖协议,团队交互协议描述了另一类主体交互模式,对主体交互模块的设计具有指导意义. 相似文献

现在已经存在的不同异构间的移动Agent系统已经阻碍了移动Agent间的互操作。虽然已经存在一些解决方案,但都限制在某一方面。该文给出了一个:基于抽象层,并遵循FIPA标准的移动Agent互操作模型。 相似文献

提出一种基于模板分析方法,说明Agent之间通信如何使用这种方法去构造和分解消息,并说明这种方法减少了在ACL上的假设和消息格式的使用。模板的应用降低了Agent之间相互操作的需求,允许Agent在一个开放的多Agent系统中通信,可以事先不考虑缺少ACL协议和消息格式要求。 相似文献

阐述了将传统的P2P服务扩展到无线网络环境的重要性、可行性、和面临的主要困难。在分析了一种系统架构MobiShare的基础上,提出了一种新的应用Agent技术实现P2P服务扩展的系统架构。该系统应用CAS对区域内的移动终端设备提供的服务进行管理;应用多Agent技术实现对环境信息的实时检测以实时更新服务的描述;应用移动Agent迁移技术实现对服务的发现和收集;异构Agent之间通信的描述则采用FIPA ACL语言。最后通过模拟实验说明了应用该系统架构所具有的优越性 相似文献

The Foundation for Intelligent Physical Agents (FIPA) standardisation body has produced a set of specifications outlining a generic model for the architecture and operation of agent-based systems. The FIPA'97 Specification Part 2 is the normative specification of an Agent Communication Language (ACL) which agents use to talk to each other. The FIPA ACL is based on speech act theory. Its syntax is defined by performatives parameterised by attribute value pairs, while its semantics is given in terms of the mental states of the communicating agents (i.e. intentionality). However, it is not clear if the formal semantics is meant as a normative or informative specification. The primary purpose of this paper is then to give an expository analysis of the FIPA ACL semantics to clarify this situation. We also offer some guidelines motivated from our own analysis, experience and understanding of how the semantic definitions and logical axioms should be interpreted and applied. However, our conclusion is that while the FIPA ACL specification offers significant potential to a developer using it for guidance, there are limitations on using an agent's mental state to specify the meaning of a performative as part of a normative standard. We consider some possibilities for making improvements in this direction. 相似文献

Agent通信语言综述 总被引:14,自引:0,他引:14
作为Agent间通信的关键,Agent通信语言(AgentCommunicationLanguage,ACL)已经得到学术界和企业界的广泛研究。在综合分析国内外有关ACL文献的基础上,总结了ACL的起源和发展,设计了ACL的基本框架;并在此框架基础上,分析比较了各种ACL,尤其对两种主流ACL:KQML(KnowledgeQueryandManagementLanguage)和FIPAACL(TheFoundationforIntelligentPhysicalAgentsACL)进行比较分析,最后对ACL研究热点做了总结,概括了可能的进一步研究方向。 相似文献

We show how a formal framework for the observation issue in computer systems can be used for the specification of an agent behavior, abstracting away from agent inner details while focusing on its interactive behavior. This model can also be used as a specification of agent communication languages (ACLs), providing the proper abstraction level to represent the conditions causing an agent to send a message, as well as its effect on the receiving agent. In particular, this approach generalizes upon existing ACL semantics, such as FIPA ACL, that relate agent communicative acts to the agent mental state. Since the observation framework induces a more abstract architecture than other known approaches, our semantics are likely to be applicable to a wider set of agent architectures, thus better supporting standardization aims. Some application examples are shown, describing how various aspects of ACL semantics can be specified within our framework. 相似文献

The State of the Art in Agent Communication Languages 总被引:5,自引:1,他引:4

Like societies of humans, there is a need for agents in a multi-agent system to rely on one another, enlist the support of
peers in order to solve complex tasks. Agents will be able to cooperate only through a meaningful communication language that
can bear correctly their mental states and convey precisely the content of their messages. In search for the ideal agent communication
language (ACL), several initiatives like the pioneering work of the Knowledge Sharing Effort and the Foundation for Intelligent
Physical Agents (FIPA) are paving the way for a platform where all agents would be able to interact regardless of their implementation
environment. ACL is a new field of study that could gain from a survey in expanding its application areas. For this purpose,
we examine in this paper the state of the art in ACL design and suggest some principles for building a generalized ACL framework.
We then evaluate some existing ACL models, and present the current issues in ACL research, and new perspectives.
