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.
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)

Information and Communications Technologies (ICTs) offer great potential to enable and enhance climate change adaptation projects, programmes and activities. As yet these roles have received relatively little systematic consideration. In this paper we outline the nature of… (More)
