Apps from Open Data

Chicago Health Atlas

• Restaurant inspection predictive analytics actively operates off of data from the Chicago Open Data portal– Predicts restaurants most likely to have serious or

critical health code violations– Allows inspectors to prioritize those restaurants,

helping remediate potential problems faster’

• This is the latest turn in the open data movement, suggesting all [releasable] government data should be released

• Even if we don’t think it’s that valuable to release, others might– “One man’s garbage [data] is another man’s gold[en data]”– E.g. Snowplow tracking; NYS nursing home beds//Irene

• Timely and consistent publication of public information and data is an essential component of an open and effective government
