The big picture, from grids and clouds to crowds: a data collective computational intelligence case proposal for managing disastersBessis, Nik; Asimakopoulou, Eleana; French, Tim; Norrington, Peter; Xhafa, Fatos (IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC, 2010)Much work is underway within the broad next generation technologies community on issues associated with the development of services to foster collaboration via the integration of distributed and heterogeneous data systems and technologies. Various technology-driven paradigms have emerged, including Web Services, Web 2.0, Pervasive, Grids and Cloud Computing. Recently, some new paradigms have emerged, including Situated Computing and Crowd Sourcing. In this exploratory paper, we aim to be visionary, thus, we offer an overview highlighting relationships between these paradigms, the goal is to present how these fit into the broader picture of IT. More specifically, to discuss how these could help coin and prompt future direction of their usage (integration) in various real-world scenarios. A disaster management scenario is presented to illustrate the big picture's model architecture, as well as briefly discuss the potential impact resulting from the collective computational intelligence approach.
Towards a corporate governance trust agent scoring model for collaborative virtual organisationsFrench, Tim; Bessis, Nik; Xhafa, Fatos; Maple, Carsten (Inderscience, 2011)In this 'visionary' paper, we describe how a semiotic ladder, together with a supportive trust agent, can be used to address 'soft' trust issues in the context of collaborative Virtual Organisations (VOs). The intention is to offer all parties better support for trust (as reputation) management, including the reduction of risk and improved reliability of VO e-services. The semiotic ladder is intended to support the VO e-service life cycle through the articulation of e-trust at various levels of system abstraction, including trust as a measurable confidence level. A novel trust agent is used to provide the consumer with an objective measure of the trustworthiness of the e-service at runtime, just prior to its actual consumption. Specifically, VO consumer confidence level is informed via a set of Corporate Governance (CG) scores, which are used as a trust proxy for the 'real' owner of the VO.
