Hello everyone, The next Research Showcase will be live-streamed on Wednesday, December 18, at 9:30 AM PST/17:30 UTC. We’ll have a presentation from Fabian Suchanek on incomplete knowledge bases and one from Brian Keegan about Wikipedia and the 2016 US Presidential election. YouTube stream: https://www.youtube.com/watch?v=b4VrphM_TTA As usual, you can join the conversation on IRC at #wikimedia-research. You can also watch our past research showcases here: https://www.mediawiki.org/wiki/Wikimedia_Research/Showcase This month's presentations: Making Knowledge Bases More Complete By Fabian Suchanek, Télécom Paris, Institut Polytechnique de Paris A Knowledge Base (KB) is a computer-readable collection of facts about the world (examples are Wikidata, DBpedia, and YAGO). The problem is that these KBs are often missing entities or facts. In this talk, I present some new methods to combat this incompleteness. I will also quickly talk about some other research projects we are currently pursuing, including a new version of YAGO.

How did the production and consumption of political information on Wikipedia mirror the dynamics of the 2016 U.S. Presidential campaign? Drawing on systems justification theory and methods for measuring the enthusiasm gap among voters, this paper quantitatively analyzes the candidates' biographical and related articles and their editors. Information production and consumption patterns match major events over the course of the campaign, but Trump-related articles show consistently higher levels of engagement than Clinton-related articles. Analysis of the editors' participation and backgrounds show analogous shifts in the composition and durability of the collaborations around each candidate. The implications for using Wikipedia to monitor political engagement are discussed.
