The winners of the Data Science award were a team that did an analysis of a million tweets about feminism. The team members were Zafarali Ahmed, Jerome Boisvert-Chouinard, Dave Gurnsey, Nancy Lin, Reda Lotfi and David Taylor. Congratulations to the whole team!
David posted a couple of writeups of what they did: an overview of their findings on his Prooffreader blog as well as a nerdier writeup of their methodology on Prooffreader Plus (their methodology is what won them the prize!). You can also see the deck they presented at the end of the Hackathon.
Here are a couple photos of the event:
