Google Unveils Data Cleanser
Once known as "Freebase Gridworks", Google has since transformed and improved on the acquired Metaweb's software as their own. Tagged as Google Refine, the open-source application is primarily a collection of tools designed to analyze and clean up data sets. For example, it can detect variant spellings of a word in a data set and replace them with the appropriate term.
