OpenRefine (formerly GoogleRefine) is a powerful tool for working with messy data: cleaning it; transforming it from one format into another; extending it with web services; and linking it to databases.  The session builds on material covered in the Introduction to OpenRefine workshop last year. We will review some of the basic capabilities, then explore advanced data operations, installing extensions, using GREL (General Refine Expression Language) for data manipulation, data reconciliation, and named entity recognition. Some experience with OpenRefine or GoogleRefine is expected.

Participants are strongly encouraged to bring a laptop.  Laptops are available for checkout from the Library information desk (Pitt ID required); if you will be checking out a library laptop please give yourself extra time before the workshop.
