Wikipedia announced they have decided to give away their search data to the public for free.
Yea, they would just give away search data to anyone would wanted to download it.
Shortly after they announced this, they decided to "temporarily taken down this data to make additional improvements to the anonymization protocol related to the search queries."
My first reaction when I saw that Wikipedia was releasing this information was, privacy issue!
They may search for family information, medical conditions, religious beliefs, political beliefs and so on.
If you can match those search patterns to the same user (i.e. their IP address), you can technically back track who the searcher is and build a profile of the user and their beliefs and tastes.
Great for marketers, but potentially horrible for the privacy of the searcher.
Back in 2006, AOL released this data and was blasted for doing so.
In fact, the New York Times profiles one of those searchers, Searcher No. 4417749 to prove this point.
Heck, they even made a movie around this leaked search data.
So when I heard Wikipedia is doing the same, I was a bit surprised.
Why did they decide to release it?
it provides valuable feedback to our editor community, who can use it to detect topics of interest that are currently insufficiently covered.
we can improve our search index by benchmarking improvements against real queries.
we give outside researchers the opportunity to discover gems in the data.
Again, Wikipedia has pulled down the data until they can figure out how to better anonymize the data.
