AOL has published this week 36 millions search queries from more than 650,000 US users. The data has been anonymized, but you can still use the queries to find information about each person. The data, released by AOL Labs as a research material, stirred a lot of negative controversy, and it was removed from AOL's site. AOL spokesman Andrew Weinstein confessed: "This was a screw-up, and we're angry and upset about it. It was an innocent enough attempt to reach out to the academic community with new research tools, but it was obviously not appropriately vetted, and if it had been, it would have been stopped in an instant."
The valuable data is still available on other sites, including this searchable database and this mirror (439 MB, tgz file). You can find users like 1983280 and track all the searches between March 1st and May 31st this year. The data set includes these fields: UserID, Query, Query Time, Clicked Rank, Destination Domain. So what can you find out about our user? She's a teenager interested in politics, she's from Washington DC, she likes photography and American Idol, one of her parents died and she's about to get married. From other users, you can find the name, the address, the work place and other details that allows identifying the person. New York Times discovered the user no. 4417749, Thelma Arnold, a 62-year-old widow who lives in Lilburn. AOL didn't realize that, in the name of the science, has comitted the biggest privacy breach a search engine ever did. Google didn't let the Government to obtain a similar data set, and AOL, who gets the search results from Google, releases them to the public.
Despite all the privacy considerations, the database is fascinating and it could be the subject of a book about human nature.
