Using rummble as a personalised travel guide

Abstract

Rummble Ltd (www.rummble.com) is an online mobile local content provider that gives users access to trusted spatially-located content via the web and mobile. Rummble brands itself as a "Personalised travel guide written by your friends". Users sign up and build a social network. They upload reviews of places they have visited and provide ratings for them. The service carries out a trust network analysis on each person's friends network and determines the individually most trusted people in their network. The service can then determine the likelihood a user will enjoy visiting a particular place by combining the trust (and ratings) for each person who has reviewed the place in question. For example, a user visiting the Barri-Gotic in Barcelona can immediately find via their mobile phone bars and restaurants they might like which have been reviewed by trusted people from their friends network and rated highly. © 2008 International Federation for Information Processing.
