This paper describes a semi-automated process, framework and tools for harvesting, assessing, improving and maintaining high-quality linked-data. The framework, known as DaCura 1 , provides dataset curators, who may not be knowledge engineers, with tools to collect and curate evolving linked data datasets that maintain quality over time. The framework(More)
Centralized semantic sensor network systems gradually show performance degradation as the scale of the sensor network increases. Thus systems based on distributed approaches with local, autonomous management features are urgently required. In order to achieve local autonomy, it is necessary to push semantics towards the edge of the sensor network, but this(More)
OWL (Web Ontology Language) reasoning has been extensively studied since its standardization by W3C. While the prevailing research in the OWL reasoning community has targeted faster, larger scale and more expressive OWL reasoners, only a small body of research is focused on OWL reasoning for resource-constrained devices such as mobile phones or sensors.(More)
— Modern smart buildings utilize sensor networks for facilities management applications such as energy monitoring. However as buildings become progressively more embedded with sensor networks, the challenge of managing and maintaining the sensor networks themselves becomes ever more significant. As a cost-sensitive activity, facilities management(More)
—Increasingly there is a demand for more scalable fault management schemes to cope with the ever increasing growth and complexity of modern networks. Current distributed fault correlation schemes typically adopt rigid topologies, which require great effort in topology configuration. In this paper, we introduce a distributed fault correlation scheme which(More)

To increase the interoperability and accessibility of data in sensor-rich systems, there has been a recent proliferation of the use of Semantic Web technologies in sensor-rich systems. Quite a range of such applications have emerged, such as hazard monitoring and rescue, context-aware computing, environmental monitoring, field studies, internet of things,(More)
— Existing approaches for selecting the most appropriate reasoner for different semantic applications mainly relies on discussions between application developers and reasoner experts. However this approach will become inadequate with the increasing adoption of Semantic Web technologies in applications from different domains and the rapid development of OWL(More)
