It has been recently claimed that human movement is highly predictable. While an upper bound of 93% predictability was shown, this was based upon human movement trajectories of very high spatiotemporal granularity. Recent studies reduced this spatiotemporal granularity down to the level of GPS data, and under a similar methodology results once again(More)
In this paper we present AnswerTree, a collaborative mobile location-based educational game designed to teach 8-12 year olds about trees and wildlife within the University of Nottingham campus. The activity is designed around collecting virtual cards (similar in nature to the popular Top Trumps games) containing graphics and information about notable(More)
ZigZag is a paradigm of hypermedia that consists of a multidimensional system of principled interconnections. Its basic features and specifications are now well known, but despite this, very few practical applications have been described or discussed. This paper examines two projects as case studies. These projects both use the unique properties of ZigZag(More)
This paper reports on the generation of unambiguous clusters of URLs from clickthrough data from the MSN search query log excerpt (the RFP 2006 dataset). Selections (clickthroughs) by a single user from a single query can be assumed to have some mutual semantic relevance, and the URLs coselected in this way can be aggregated to form single-sense clusters.(More)
ZigZag is a unique hyperstructural paradigm designed by the hypertext pioneer Ted Nelson. It has piqued a lot of interest in the hypertext community in recent years because of its aim of revolutionizing electronic access to information and knowledge bases. In ZigZag information is stored in cells that are arranged into lists organized along unlimited(More)
Previous work on the Daily Car-Pooling problem includes an algorithm that consists of greedy assignment alternating with random perturbation. In this study, we examine the effect of varying the move acceptance policy, specifically Late-acceptance criteria with and without reheating. Late acceptance-based move acceptance criteria were chosen because there is(More)
It is increasingly rare to encounter a Web service that doesn't engage in some form of automated recommendation, with Collaborative Filtering (CF) techniques being virtually ubiquitous as the means for delivering relevant content. Yet several key issues still remain unresolved, including optimal handling of cold starts and how best to maintain user-privacy(More)
In this paper we concern ourselves with Service-Oriented Architectures (SOA) in the “business to consumer” (B2C) arena. In particular we consider the services required to enable consumers to combine data they possess with data held about them by businesses and government. We introduce the concept of Dataware as the logical federation of data(More)
