在基于辩论的多agent系统研究中,agent之间的对话博弈一般是双方的,然而现实中的辩论却常常涉及到多方参与者,如何实现多agent系统的多方对话博弈是当前的研究热点之一。用于多方论据博弈的辩证分析模型(DAM-MAG)是一种借鉴中国武术擂台比武思想,将多方对话博弈转化为若干个双方对话博弈的理论模型。DAM-MAG的难点在于多方对话博弈协议的设计和实现。为此,基于该理论模型提出了一种多方对话博弈协议。该协议提供了通过双方对话博弈来解决多方对话博弈问题的方法,为解决多agent系统的多方对话博弈提供了新的途径。 相似文献

多Agent对话系统是一个能够模仿该领域专家进行辩论的计算机程序。它可以根据当前用户输入的信息进行逻辑分析和判断,最终通过辩论得出对该领域某一具体问题的建议。其基本过程是参与对话的Agent根据系统的知识库围绕主题构造出争议,通过对话构造争议之间的攻击关系,最后根据辩论算法确定可接受争议集,该系统能够模拟专家进行分析和决策,以解决那些需要专家才能做出决策的复杂问题。 相似文献

如今,多agent系统(multi-agent system,简称MAS)被广泛用于开发各种应用系统.当前,开放、动态、难控的计算平台要求软件系统能够根据系统自身及其环境状态信息及其改变,动态地调节自身的行为,即具备一定的上下文感知能力.然而,现有工作并未就如何向既有的MAS应用系统引入上下文感知能力提出有效的解决方案.依照关注分离原则,结合面向上下文程序设计技术(context-oriented programming,简称COP)、反射技术(reflection)以及代码植入技术(code instrumentation),提出了一套MAS系统上下文感知增强框架和底层支撑技术.开发人员可以在既有应用源码不可得的情况下,自动地将指定agent类型转换为(扩展为)具有上下文感知能力的agent类型.此外,利用底层运行支撑环境,系统管理员可以在系统运行时刻动态地调整指定agent的上下文感知行为. 相似文献

在可计算论辩模型中,论辩语义的证明理论解决如何判定给定论辩语义中某个论证的证成状态的问题,这通常需要建构与之对应的论证博弈模型。论证博弈发生在正方和反方的论证交互过程中,正反双方都是通过给出攻击论证来质疑对方的论证和辩护己方的论证,正方只有在论证博弈中获胜才能使其初始论证获得确定的证成状态。文中定义了一种被称为BRD-论辩语义的渐进式论辩语义,不同于Dung的抽象论辩语义,它是在结构化论辩框架ASPIC+中嵌入了一种用于计算论证的强度和证成度的循环语义。为了给出该语义的证明理论,建构了与之对应的论证博弈模型。 相似文献

Communication between agents needs to be flexible enough to encompass together a variety of different aspects such as, conformance to society protocols, private tactics of the individual agents, strategies that reflect different classes of agent types (or personal attitudes) and adaptability to the particular external circumstances at the time when the communication takes place. In this paper, we propose an argument-based framework for representing communication theories of agents that can take into account in a uniform way these different aspects. We show how this approach can be used to realize existing types of dialogue strategies and society protocols in a way that facilitates their modular development and extension to make them more flexible in handling different or special circumstances. 相似文献

As utility calculus cannot account for an important part of agents' behaviour in Multi-Agent Systems, researchers have progressively adopted a more normative approach. Unfortunately, social laws have turned out to be too restrictive in real-life domains where autonomous agents' activity cannot be completely specified in advance. It seems that a halfway concept between anarchic and off-line constrained interaction is needed. We think that the concept of right suits this idea. Rights improve coordination and facilitate social action in Multi-Agent domains.Rights allow the agents enough freedom, and at the same time constrain them (prohibiting specific actions). Besides, rights can be understood as the basic concept underneath open normativesystems where the agents reason about the code they must abide by. Typically, in such systems this code is underspecified. On the other hand, the agents might not have complete knowledge about the rules governing their interaction. Conflict situations arise, thus, when the agents have different points of view as to how to apply the code. We have extended Parsons's et al. argumentation protocol (Parsons et al. 1998a, b) to normative systems to deal with this problem. 相似文献

One of the most difficult problems in Multi-Agent Systems (MAS) involves representing the knowledge and beliefs of an agent which performs its tasks in a dynamic environment. New perceptions modify this agent’s current knowledge about the world, and consequently its beliefs about it also change. Such a revision and update process should be performed efficiently by the agent, particularly in the context of real-time constraints. In the last decade argumentation has evolved as a successful approach to formalize defeasible, commonsense reasoning, gaining wide acceptance in the MAS community by providing tools for designing and implementing features, which characterize reasoning capabilities in rational agents. In this paper we present a new argument-based formalism specifically designed for representing knowledge and beliefs of agents in dynamic environments, called Observation-based Defeasible Logic Programming (ODeLP). A simple but effective perception mechanism allows an ODeLP-based agent to model new incoming perceptions, and modify the agent’s knowledge about the world accordingly. In addition, in order to improve the reactive capabilities of ODeLP-based agents, the process of computing beliefs in a changing environment is made computationally attractive by integrating a “dialectical database” with the agent’s program, providing pre-compiled information about previous inferences. We present algorithms for managing dialectical databases as well as examples of their use in the context of real-world problems. 相似文献
