    Norm-based and commitment-driven agentification of the Internet of Things

    There are no doubts that the Internet-of-Things (IoT) has conquered the ICT industry to the extent that many governments and organizations are already rolling out many anywhere,anytime online services that IoT sustains. However, like any emerging and disruptive technology, multiple obstacles are slowing down IoT practical adoption including the passive nature and privacy invasion of things. This paper examines how to empower things with necessary capabilities that would make them proactive and responsive. This means things can, for instance reach out to collaborative peers, (un)form dynamic communities when necessary, avoid malicious peers, and be “questioned” for their actions. To achieve such empowerment, this paper presents an approach for agentifying things using norms along with commitments that operationalize these norms. Both norms and commitments are specialized into social (i.e., application independent) and business (i.e., application dependent), respectively. Being proactive, things could violate commitments at run-time, which needs to be detected through monitoring. In this paper, thing agentification is illustrated with a case study about missing children and demonstrated with a testbed that uses different IoT-related technologies such as Eclipse Mosquitto broker and Message Queuing Telemetry Transport protocol. Some experiments conducted upon this testbed are also discussed

    On the emergent Semantic Web and overlooked issues

    The emergent Semantic Web, despite being in its infancy, has already received a lotof attention from academia and industry. This resulted in an abundance of prototype systems and discussion most of which are centred around the underlying infrastructure. However, when we critically review the work done to date we realise that there is little discussion with respect to the vision of the Semantic Web. In particular, there is an observed dearth of discussion on how to deliver knowledge sharing in an environment such as the Semantic Web in effective and efficient manners. There are a lot of overlooked issues, associated with agents and trust to hidden assumptions made with respect to knowledge representation and robust reasoning in a distributed environment. These issues could potentially hinder further development if not considered at the early stages of designing Semantic Web systems. In this perspectives paper, we aim to help engineers and practitioners of the Semantic Web by raising awareness of these issues

    Why States Create International Tribunals: A Response to Professors Posner and Yoo

    A recent article in the California Law Review by Professors Eric Posner and John Yoo, Judicial Independence in International Tribunals, argues that the only effective international tribunals are dependent tribunals, by which the authors mean ad hoc tribunals staffed by judges closely controlled by governments through the power of reappointment or threats of retaliation. Independent tribunals, by contrast, meaning tribunals staffed by judges appointed on similar terms as those in domestic courts, pose a danger to international cooperation. According to Posner and Yoo, independent tribunals are suspect because they are more likely to allow moral ideals, ideological imperatives or the interests of other states to influence their judgments. In this response, we identify the many shortcomings in the theory, methodology, and empirics in Judicial Independence in International Tribunals. We do so to challenge the authors\u27 core conjecture: that formally dependent international tribunals are correlated with effective judicial outcomes. We then offer our own counter-theory; a theory of constrained independence in which states establish independent international tribunals to enhance the credibility of their commitments and then use more fine grained structural, political, and discursive mechanisms to limit the potential for judicial excesses

    A multi-agent system with application in project scheduling

    Get PDF
    The new economic and social dynamics increase project complexity and makes scheduling problems more difficult, therefore scheduling requires more versatile solutions as Multi Agent Systems (MAS). In this paper the authors analyze the implementation of a Multi-Agent System (MAS) considering two scheduling problems: TCPSP (Time-Constrained Project Scheduling), and RCPSP (Resource-Constrained Project Scheduling). The authors propose an improved BDI (Beliefs, Desires, and Intentions) model and present the first the MAS implementation results in JADE platform.multi-agent architecture, scheduling, project management, BDI architecture, JADE.
