This paper's goal is to design an intrusion detection system for a distributed environment adapted for developing and monitoring agents. The idea is to endow the agent platform with a high level of immunity by integrating the intrusion detection system based on artificial intelligence techniques. The agent platform itself is improved with advanced mechanisms for monitoring, analyzing, discovering, learning, and detecting intruders. The most important aspect of this platform is represented by its capability of detecting and rejecting possible intruders. The paper discusses in a critical way the traditional views of intrusion detection and analyzes the more complex approach to human immune system. The proposed architecture is a layered one and the paper describes the role and capability of each layer. The novelty of this approach is proved by the monitoring agents' activities regarding services and actions which are translated in terms of system's resources: processor, memory and bandwidth. The monitoring process is the key of the intrusion detection mechanism.

Business agents have precise responsibilities assigned to organizational business roles. They collaborate and interact in order to achieve the business goals of the organization. The activity of business agents follows behavioral patterns that are specified according to the business rules of the organization. In this paper we present how business process models that define organizational activity can be modeled and implemented using agent-oriented programming. In particular we present how business processes captured as role-activity diagrams can be formalized and enacted using agentSpeak programs. This approach of combining sound methods of business process and agent-oriented modeling opens new possibilities for the development of agent-based business organizations.

This paper proposes a multi-agent approach to power system restoration. The proposed system consists of several Bus agents (BAGs) and a single Facilitator agent (FAG). A BAG is developed to decide a sub-optimal target configuration after faults occur by interacting with other BAGs, while a FAG is developed to act as a manager for the decision process. The interaction of several simple agents leads to a dynamic system allowing efficient approximation of a solution. It is shown from simulation results that this method is able to obtain sub-optimal target configurations which are the same as ones obtained by a mathematical programming approach.

Mental attributes of agents are investigated in a framework of transition systems and abstract languages. The mental attitudes are related to beliefs, desires/goals and intentions/plans which are known from so-called BDI-architectures. Actions and events are more stressed than states. This allows the consideration of global and individual aspects of belief, desire, intentions etc. in a simple unified formalism.

Construction and use of software agents for industrial and business computer systems is a well-known subject for professional development teams. But the full potential of agent-oriented programming usually remains hidden to these groups and agents are usually not exploited to their full potential. This study shows the description and implementation of a number of techniques created to face the construction of agents composed of a number of behaviors that may be debugged and revised in a step-by-step fashion, both at design and at runtime. The set of techniques also include a mechanism for managing the orchestration of behaviors, what gives the development teams insight on the final behavior resulting from the combination of the individual ones. These techniques allow the application of agile software development principles to multiagent environments, making it easier to integrate these kind of software artifacts into complex projects using this paradigm. The paper also describes two practical sample use cases where these techniques are employed: the application of the techniques to the simple JADE Dummyagent and to complex rule-based agents that run behaviors based on CLIPS or JESS rules.

We provide a taxonomy of concurrency models for BDI frameworks, elicited by analysing state-of-the-art technologies, and aimed at helping both BDI designers and developers in making informed decisions. Comparison among BDI technologies w.r.t. concurrency models reveals heterogeneous support, and low customisability.

The paper presents a new Learning Technology System Architecture that is implemented using agents and semantic Web. The architecture is divided into client and server parts to facilitate adaptivity in various configurations such as online, offline and mobile scenarios. The implementation of this approach to architecture is discusses in SiDeC (authoring tool) and Evaluation System, which are researching, evaluating and developing an integrated system for Web-Based Education, with powerful adaptivity for the management, authoring, delivery and monitoring of such material.

To support the practical development of intelligent agents, several programming languages have been introduced that incorporate concepts from agent logics: on the one hand, we have languages that incorporate beliefs and plans (i.e., procedural goals), and on the other hand, languages that implement the concepts of beliefs and (declarative) goals. We propose the agentprogramming language Dribble, in which these features of procedural and declarative goals are combined. The language Dribble thus incorporates beliefs and goals as well as planning features. The idea is, that a Dribble agent should be able to select a plan to reach a goal from where it is at a certain point in time. In order to do that, the agent has beliefs, goals and rules to select plans and to create and modify plans. Dribble comes with a formally defined operational semantics and, on top of this semantics, a dynamic logic is constructed that can be used to specify and verify properties of Dribble agents. The correspondence between the logic and the operational semantics is established.

Reactive behaviour in Belief Desire Intention (BDI)-based models and architectures adopted in agentprogramming is typically specified in terms of reactive plans not bound to any specific goal. In this paper, we present and discuss an extension of the plan model used in BDI programming languages in which goal-based plans encapsulate both proactive and reactive behaviour. This brings important benefits both to the practice of agentprogramming and in supporting agent reasoning at runtime. The approach is evaluated through concrete implementations based on two existing agentprogramming platforms, namely Jason and ASTRA.

The Internet and Web have brought in a new era of information sharing and openedup countless opportunities for people to rethink and redefine communication. Withthe development of network-related technologies, a Client/Server architecture has becomedominant in the application layer of the Internet. Nowadays network nodesare behind firewalls and Network Address Translations, and the centralised design ofthe Client/Server architecture limits communication between users on the client *** the conflicting goals of data privacy and data openness is difficult and inmany cases the difficulty is compounded by the differing solutions adopted by differentorganisations and companies. Building a more decentralised or distributed environmentfor people to freely share their knowledge has become a pressing challengeand we need to understand how to adapt the pervasive Client/Server architecture to thismore fluid *** thesis describes a novel framework by which network nodes or humans can interactand share knowledge with each other through formal service-choreography specificationsin a decentralised manner. The platform allows peers to publish, discoverand (un)subscribe to those specifications in the form of Interaction Models (IMs). Peergroups can be dynamically formed and disbanded based on the interaction logs ofpeers. IMs are published in HTML documents as normal Web pages indexable bysearch engines and associated with lightweight annotations which semantically enhancethe embedded IM elements and at the same time make IM publications complywith the Linked Data principles. The execution of IMs is decentralised on each peer viaconventional Web browsers, potentially giving the system access to a very large usercommunity. In this thesis, after developing a proof-of-concept implementation, wecarry out case studies of the resulting functionality and evaluate the implementationacross several *** increasing number of service providers have began to look for
