Background

• Controlled vocabularies improve information
  retrieval and discovery
• But, costly to index considering the amount of
  digital documents
• Social tagging holds the promise of reducing
  indexing costs
• But, tags entirely uncontrolled
• Many tag only to organise own documents
• May identify new trends and hot concepts
• Social tagging part of Web 2.0 trend to user
  added value/content
• eg see http//www.youtube.com/watch?v6gmP4nk0EOE
  
• We investigate the combination of controlled and
  folksonomy approaches to support resource
  discovery in digital collections

EnTag Purpose

• Investigate whether use of suggestions from an
  established controlled vocabulary can help move
  social tagging beyond personal bookmarking to aid
  resource discovery and retrieval
• Collaborative research project funded by JISC
• - UKOLN/Bath, Glamorgan, Intute, and other
  partners
• http//www.ukoln.ac.uk/projects/enhanced-tagging/
  
• Glamorgan role
• Develop and evaluate a Demonstrator combining DDC
• (Dewey Decimal Classification) and social tagging
• Compare pure social tagging system with
  advanced version that offers suggestions
  drawing on DDC
• Operating on an extract of the JISC (government
  funded)
• Intute Politics digital collection
