2. 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?v=6gmP4nk0EOEhttp://www.youtube.com/watch?v=6gmP4nk0EOE We investigate the combination of controlled and folksonomy approaches to support resource discovery in digital collections

3. 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 http://www.intute.ac.ukhttp://www.intute.ac.uk
