    Setting up an EC2 instance for TwitterGoggles

    by  • May 13, 2013 • Code, Research • 0 Comments

    TwitterGoggles requires Python 3.3. I’m new to Python, and 3.3 is (relatively) new to everyone. So, getting help is both necessary and challenging. I want to run TwitterGoggles on Amazon EC2 instances, so I’m setting up an AMI that has all of the requirements: gcc 4.6.3 git 1.8.1.4 mlocate 0.22.2 MySQL 5.5 Python 3.3...

    Calculating Geometric Mean in NodeXL

    by  • November 28, 2012 • Research, Social Computing • 2 Comments

    My social networks reading group read De Choudury et al’s WWW’10 paper about inferring social networks from email (citation’s below) this week, and I was inspired by our discussion to calculate geometric means for Twitter mentions. You can read elsewhere about the public officials and social media project, but basically I have a bunch...

    Congress Hashtag Networks

    This morning, I led an hour of WebShop 2012. At the beginning of the talk, I asked the audience, especially students, to brainstorm questions about public officials and Twitter, specifically. You can see the list we generated as a Google doc. Many of those questions my colleagues and I are already investigating, but like I...

    U.S. Congressional Mention Networks

    by  • July 11, 2012 • Politics, Research, Social Computing • 0 Comments

    I used the Twitter Database Server and my own Twitter-collectors to gather 42,813 tweets posted by 417 elected members of Congress (69 Senators and 348 Representatives) between December 22, 2011 and March 15, 2012. From those tweets, I made a network based on when Members of Congress mentioned each other and used NodeXL to analyze and graph the...

    One-mode Projections in NodeXL

    by  • May 14, 2012 • Code, Research, Social Computing • 0 Comments

    Many of the networks I retrieve and analysis are two-mode affiliation networks – meaning they’re networks of people connected to share objects or communities. For instance, Senators using the #gopconference hashtag on Twitter, where I’ll have an edgelist of Senators and the hashtags they use. NodeXL, my free network analysis software of choice, doesn’t currently...
