This chapter focuses on the World Wide Web (Web) as a provider of shared information landscapes. It reviews our work to design 3D spaces for information navigation and social interaction, and suggests an approach to such design based on an experiential theory of meaning. The increasing use of virtual 3D space in information environments is noted, and Personal Spaces are contrasted with Public P...

TV White Spaces have recently been proposed as an alternative to alleviate the spectrum crunch, characterised by the need to reallocate frequency bands to accommodate the ever-growing demand for wireless communications. In this paper, we discuss the motivations and challenges for collecting spectrum measurements in developing regions and discuss a scalable system for communities to gather and p...

University campuses are busy places for wireless client traffic coming from Wi-Fi connections and other wireless devices that contend for the 2.4 GHz frequencies space that most campus Wi-Fi networks use currently. This is making the 2.4 GHz frequency unsuitable for WiFi connection due to too much interference from other devices as well as from Wi-Fi connections themselves. TV white space could...

Critical Discourse Analysis (CDA) is a multidisciplinary holistic, consisting of a number of different theoretical approaches to the microlevel analysis of text and talk that has to do with the social and/or political. These various methodological approaches are unified, however, by a macrolevel social critique which maintains that social inequality may be enacted, sustained and legitimised thr...

This paper presents novel dissimilarity space specially designed for interactive multimedia retrieval. By providing queries made of positive and negative examples, the goal consists in learning the positive class distribution. This classification problem is known to be asymmetric, i.e. the negative class does not cluster in the original feature spaces. We introduce here the idea of Query-based ...

As an old lighthouse (PHAROS in ancient Greek) provided a proper navigation tool for people to find their route when lost at sea, in the same way PHAROS will ensure the right way to navigate in the modern enormous information ocean.
