Computational Social Science Hack Day 2014

GT and Emory Computational Social Science enthusiasts again joined forces — this time for a hack day at Georgia Tech — following up on a fun and successful workshop at Emory in November. The 20 participants from the two universities pursued a variety of projects, including:

  • Structural balance theory in comic book narratives (Amish, Sandeep, and Vinay, with help from Vinodh)
  • Identifying noteworthy items in text from State-of-the-Union addresses (Tanushree and Yangfeng, with help from Jeff and Tom)
  • Combating the trafficking of minors, using text analysis and computer vision (Eric and Parisa)
  • Connecting spelling variation with sentiment analysis (Uma, Yi, and Yu)
  • Predicting Grammy award winners from Tweet volume (Jayita and Spurthi)
  • Mining OpenSecrets to find latent clusters of campaign donors and recipients (Jacob, Jon, and Munmun)

Since this is my blogpost, I’ll take a little more time to talk about my project. Essentially we just read in OpenSecrets data and built a matrix of donors and recipients. The sparse SVD of this matrix revealed some interesting factors. Here are the top 7 candidates and donors for each of the most interesting factors, along with my own name for the factors.

Our plan was to learn more about these factors by connecting them with text from the wikipedia pages of the companies and with the NOMINATE scores and committee memberships of the legislators. Maybe that would have been possible in a 24-hour hackathon, but we ran out of time as I was just starting to get reasonable topics for the wikipedia pages.

Wrapup
We went into the day with the goal of building and strengthening connections across disciplines and institutions, and by that metric I think the day was a success. In any case, I had a blast working with new people and trying out some new ideas, and I’m confident this will impact my research in the long run. It was also a lot of fun to work with my own students and colleagues in a more collaborative setting. Taking a day off from endless paper and proposal deadlines (and non-stop email distractions) to hack on a new project felt like a mini-vacation.
