Introduction • The problem • Research • Solution • Application • The future Brightonart The Guardian 09.11.2010

The Problem • People searching for Music and not finding Piano teachers • Freetagging vocabularies • Diverging folksonomies Brightonart The Guardian 09.11.2010

Research • 1. Collaborative Creation of Communal Hierarchical Taxonomies in Social Tagging Systems Paul Heymann and Hector Garcia-Molina Computer Science Department, Stanford University • 2. The Structure of Collaborative Tagging Systems Scott A. Golder and Bernardo A. Huberman Information Dynamics Lab, HP Labs • 3. Clustering Tags in Enterprise and Web Folksonomies Edwin Simpson HP Labs http://www.hpl.hp.com/techreports/2008/HPL-2008-18.pdf Brightonart The Guardian 09.11.2010

Solution • NCO • Normalised Co-Occurrence • Inference to semantic distance • Actually co-interest • Useful community-specific data Brightonart The Guardian 09.11.2010

NCO – intersection / union Brightonart The Guardian 09.11.2010

NCO – intersection / union A B Brightonart The Guardian 09.11.2010

Sample Data Term A Term B NCO Driving Tai Chi 0 Tai Chi martial arts 0.04 National Standards Cycling Test cycling 0.23 Brightonart The Guardian 09.11.2010
