MERLIN will use off-the-shelf text mining techniques to enrich the functionality of the SHERPA-LEAP
consortial repository cross-searching service, LASSO. LASSO offers search across aggregated,
normalised metadata which is collected from London-based institutional repositories using OAI-PMH
harvesting. MERLIN will use the TerMine term extraction tool to derive terms from the full text digital
objects held at LASSO"s source repositories and, after a weighting process, enrich the LASSO
database with derived keywords. The derived terms will be exposed at various points in the LASSO
interface to support discovery. In a supplementary strand, MERLIN will apply the tools developed by
the HILT project to construct a pilot hierarchical, browsable subject tree from the text-mined keywords.
