Non-intrusive appliance load monitoring is the process of disaggregating a household’s total electricity consumption into its contributing appliances. In this paper we propose an approach by which individual appliances can be iteratively separated from an aggregate load. Unlike existing approaches, our approach does not require training data to be collected(More)
The work of the Open Hypermedia Systems Working Group (OHSWG) has lead to the creation of several hypermedia models and a common protocol for Navigational Hypertext. However none of these include a working model of context. In this paper we present how we have extended the Fundamental Open Hypermedia Model (FOHM) to include context and behaviour. We then(More)
Ubiquitous and mobile technologies provide opportunities for designing novel learning experiences that move out of the classroom. Information can be presented and interacted with in a variety of ways while exploring a physical environment. A key issue this raises is when, where, what and how much? Our research is concerned with the design, delivery and(More)
One of the results of the Open Hypermedia work of the last decade was the Fundamental Open Hypermedia Model (FOHM) capable of representing contextual structure from a variety of hypermedia domains. As the Semantic Web becomes more important it is interesting to compare its metadata language, the Resource Description Framework (RDF), with a model such as(More)
The Artequakt project is working towards automatically generating narrative biographies of artists from knowledge that has been extracted from the Web and maintained in a knowledge base. An overview of the system architecture is presented here and the three key components of that architecture are explained in detail, namely knowledge extraction, information(More)
A large amount of digital information available is written as text documents in the form of web pages, reports, papers, emails, etc. Extracting the knowledge of interest from such documents from multiple sources in a timely fashion is therefore crucial. This paper provides an update on the Artequakt system which uses natural language tools to automatically(More)
Fieldtrips, traditionally associated with science, history and geography teaching, have long been used to support children's learning by allowing them to engage with environments first-hand. Recently, ubiquitous computing (UbiComp) has been used to enhance fieldtrips in these educational areas by augmenting environments with a range of instruments, devices(More)
The interoperability work of the OHSWG identified three major domains of hypermedia that needed to be addressed, Navigational, Spatial and Taxonomic. The Fundamental Open Hypermedia Model attempted to represent all three domains in one structure and allowed context to be tackled consistently across the domains. In the paper we reflect on our experiences(More)
