Yesterday I gave a lecture for management information system (MIS) students. We were looking into definitions of data quality linked to the natural language processing approach of the Human Inference software. As discussions developed, the students could not easily agree on criteria for quality in general. In an exercxise, we talked about “good” and “bad” service. It appeared that, besides differences in taste, good service had a lot to do with expectation and fulfillment of that expectation. Of course, there were also a lot of other “requirements” for good service, but the discussion made me think of a Youtube movie I had recently seen. Seeing this movie made the jump to a solid and generic data quality definition easy: data has quality if it satifies the requirements of its intended use… Enjoy the movie!
