The Problem

• People searching for Music and not finding

Piano teachers

• Freetagging vocabularies

• Diverging folksonomies


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

Solution

• NCO

• Normalised Co-Occurrence

• Inference to semantic distance

• Actually co-interest

• Useful community-specific data


NCO – intersection / union

freetagging vocabulary: magic
