Google Refine

Paul Makepeace

Refine is a powerful, fun, fast tool for exploring, visualising, and 'cleaning' datasets.

Refine can help interactively discover patterns and sift out and transform your dataset, without scripting or programming. I'll cover core concepts: faceted browsing and clustering, as well as touch on the GR Expression Language, and reconciliation.
