    The current trend in Ubiquitous Computing is to develop smaller, smarter and adaptive devices that are continuously connected to the Internet through wireless technologies. This offers a great opportunity for cooperation between these devices. Although much related work has been performed on collaboration techniques between smart devices, most of the work is not suited for large-scale networks, where their number can increase significantly. Following this context, we investigate how information is exchanged and handled in a distributed way in a Collaborative Ubiquitous Environment. To be perceived as collaborative and proactive, each single component has to coordinate with the others in smart way. In order to achieve these key features, we introduce the concept of Global Proactive Scenarios (GPASs). To support the deployment of these scenarios, we propose a specially designed intelligent architecture for ubiquitous systems that allows them to be context-aware, proactive and self-adaptive. Furthermore, we provide an example of joint effort for illustrating the full potential of a network of interconnected proactive systems

    Third Revolution Digital Technology in Disaster Early Warning

    Networking societies with electronic based technologies can change social morphology, where key social structures and activities are organized around electronically processed information networks. The application of information and communications technologies (ICT) has been shown to have a positive impact across the emergency or disaster lifecycle. For example, utility of mobile, internet and social network technology, commercial and amateur radio networks, television and video networks and open access technologies for processing data and distributing information can be highlighted. Early warning is the key function during an emergency. Early warning system is an interrelated set of hazard warning, risk assessment, communication and preparedness activities that enable individuals, communities, businesses and others to take timely action to reduce their risks. Third revolution digital technology with semantic features such as standard protocols can facilitate standard data exchange therefore proactive decision making. As a result, people belong to any given hierarchy can access the information simultaneously and make decisions on their own challenging the traditional power relations. Within this context, this paper attempts to explore the use of third revolution digital technology for improving early warning

    Position paper on realizing smart products: challenges for Semantic Web technologies

    In the rapidly developing space of novel technologies that combine sensing and semantic technologies, research on smart products has the potential of establishing a research field in itself. In this paper, we synthesize existing work in this area in order to define and characterize smart products. We then reflect on a set of challenges that semantic technologies are likely to face in this domain. Finally, in order to initiate discussion in the workshop, we sketch an initial comparison of smart products and semantic sensor networks from the perspective of knowledge technologies

    Personalisation and recommender systems in digital libraries

    Get PDF
    Widespread use of the Internet has resulted in digital libraries that are increasingly used by diverse communities of users for diverse purposes and in which sharing and collaboration have become important social elements. As such libraries become commonplace, as their contents and services become more varied, and as their patrons become more experienced with computer technology, users will expect more sophisticated services from these libraries. A simple search function, normally an integral part of any digital library, increasingly leads to user frustration as user needs become more complex and as the volume of managed information increases. Proactive digital libraries, where the library evolves from being passive and untailored, are seen as offering great potential for addressing and overcoming these issues and include techniques such as personalisation and recommender systems. In this paper, following on from the DELOS/NSF Working Group on Personalisation and Recommender Systems for Digital Libraries, which met and reported during 2003, we present some background material on the scope of personalisation and recommender systems in digital libraries. We then outline the working group’s vision for the evolution of digital libraries and the role that personalisation and recommender systems will play, and we present a series of research challenges and specific recommendations and research priorities for the field
