The Semantic Web community could benefit greatly from 'eating its own dog food' in order to better understand the challenges and opportunities of a Semantic Web from the user perspective. In this paper we describe the deployment of Semantic Web applications and services at the 3rd European Semantic Web Conference (ESWC2006), before presenting results of an… (More)
In this paper, we describe the notion of a <i>semantic information portal</i>. This is a community information portal that exploits the semantic web standards to improve structure, extensibility, customization and sustainability. We are in the process of developing a prototype directory of environmental organizations as a demonstration of the approach and… (More)
We present an analysis of the potential worldwide demand for downloaded data and the resulting energy requirements of the cloud. Assuming that the average westerner’s media consumption moves fully online but does not rise substantially beyond current levels, and the global middle class reach western levels of consumption, we estimate the overall… (More)
In this paper we construct adaptive user profiles from tagging data. We present and evaluate an algorithm for creating such profiles, characterizing its behavior through statistical analysis.
This report describes the aims and requirements for the second of the two open demonstrators which make up workpackage 12.1. This, second, demonstrator is designed to illustrate decentralized creation and enrichment of cross-community information portals. We first describe the general problem class and the broad technical approach which the semantic web… (More)
The use of information and communication technology and the web-based products it provides is responsible for significant emissions of greenhouse gases. In order to enable the reduction of emissions during the design of such products, it is necessary to estimate as accurately as possible their carbon impact over the entire product system. In this work we… (More)
The Semantic Portals demonstrator is the second of the two open demonstrators which make up workpackage 12.1. In this report we summarize the ideas behind the demonstrator and describe the design, implementation and deployment of the demonstrator. At each stage we try to identify lessons that have been learnt from the demonstrator.
