background
Background
  • JISC funded (Information Environment 09-11, Resource Discovery strand)
  • Partners: UCL, ULCC, University of Nottingham
  • Aims
    • use off-the-shelf text-mining tools to enrich repository functionality
    • refine this work with user feedback and roll out
  • 18 months (April 2009 – September 2010)
objectives
Objectives
  • Integrate NacTEM tools in the SHERPA-LEAP consortial repository ‘LASSO’, deriving weighted keywords from source repositories.
  • Modify LASSO to expose these mined terms for discovery.
  • Work with users to ensure usefulness and user-friendliness of these modifications.
  • Experiment with thesauri: can mined terms be used to support/enhance structured navigation?
  • Roll out a MERLIN tool for plugging in to IRs.
  • Full project evaluation.
  • Dissemination.
text mining for repositories why
Text-mining for repositories: why?
  • Improve discoverability of repository content
  • Cost-effective description – cheaper than subject cataloguing…
  • Uses researchers\' own vocabularies
  • Supports interdisciplinarity
  • Adds selectivity and weight to full text indexing
  • May also be used as the basis for structured navigation
  • Examples: how MERLIN outputs might look…
lasso with terms mined from full texts
LASSO: with terms mined from full texts

Terms are weighted by frequency. Use slider to see

Progress / next steps
  • Done
    • Initial text mining
    • Integration of mined dataset with LASSO data
    • LASSO customisation under way
  • Tasks between now and Easter
    • User evaluation of LASSO; iterative improvement
    • Refinements to text mining; full integration into LASSO workflow
    • Begin thesaurus work...
