April 30, 2018

Kiran, Gianmarco, Aris and I attended the Web Conference in Lyon last week, where we presented our tutorial (link) on polarization on social media, as well as our recent, large-scale study on echo chamber on Twitter (link).
The tutorial was a particularly good opportunity to present a large number of works from the related literature of various disciplines and discuss with the audience. Part of the discussion was reported on Lemonde by William Audureau, who covered the conference for the newspaper.

Best Student Paper award at WSDM

We just heard that our paper on “Balancing Opposing Views to Reduce Controversy” (available on the ACM Digital Library) was nominated for best paper at WSDM 2017.


Update: Cornell received the best paper award – and our paper the best student paper award, with Kiran as first author.

At PyCon Finland

Yesterday, I attended PyCon Finland as a speaker. Kiran and I gave a talk on using networkx to visualize interactions on Twitter. The talk was aimed at beginner / intermediate-level programmers and we described, essentially, how we produced the plots that appear in our work¹ on polarization on social media.

The Jupyter notebook for our slides is here.

Update: The video of our talk is posted on YouTube.

In a parallel session, Clemens also presented coding material from his masters thesis on text classification.
