DVS Workshop: Open (aka Google) Refine

Open Refine (formerly Google Refine) is a tool for working with semi-structured datasets. It allows you to explore data, easily find facet patterns within data, enables simple detection of data inconsistencies, and offers quick clean-up and transformation options. Open Refine is an often intuitive but powerful tool for normalizing data before importing the dataset into a presentation application (e.g. mapping, charting, or analyzing.) In this hands-on class, we'll explore how Refine can help with common data cleaning challenges.
