Wikimedia Research/Showcase

The Monthly Research & Data Showcase is a public showcase of recent research by the Wikimedia Foundation's Research and Data Team, other WMF researchers and occasionally guest presenters. The showcase is hosted at the Wikimedia Foundation every 3rd Wednesday of the month at 11.30 Pacific Time and live streamed on YouTube.

How to attend
We live stream our research showcase every month on YouTube. The link is announced a few minutes before the showcase starts via wiki-research-l, analytics-l and @WikiResearch. You can join the conversation and participate in Q&A after each presentation by connecting to our IRC channel on freenode:

 * MoodBar -- lightweight socialization improves long-term editor retention
 * by Giovanni Luca Ciampaglia -- I will talk about MoodBar, an experimental feature deployed on the English Wikipedia from 2011 to 2013 to streamline the socialization of newcomers. I will present results from a natural experiment that measured the effect of Moodbar on the short-term engagement and long-term retention of newly registered users attempting to edit for the first time Wikipedia. Our results indicate that a mechanism to elicit lightweight feedback and to provide early mentoring to newcomers significantly improves their chances of becoming long-term contributors.

 * A bird's eye view of editor activation
 * by Dario Taraborelli -- In this talk I will give a high-level overview of data on new editor activation, presenting longitudinal data from the largest Wikipedias, a comparison between desktop and mobile registrations and the relative activation rates of different cohorts of newbies.


 * Collaboration patterns in Articles for Creation
 * by Aaron Halfaker -- Wikipedia needs to attract and retain newcomers while also increasing the quality of its content. Yet new Wikipedia users are disproportionately affected by the quality assurance mechanisms designed to thwart spammers and promoters. English Wikipedia’s en:WP:Articles for Creation provides a protected space for newcomers to draft articles, which are reviewed against minimum quality guidelines before they are published. In this presentation, describe and a study of how this drafting process has affected the productivity of newcomers in Wikipedia. Using a mixed qualitative and quantitative approach, I'll show the process's pre-publication review, which is intended to improve the success of newcomers, in fact decreases newcomer productivity in English Wikipedia and offer recommendations for system designers.

 * WikiProjects yesterday, today and tomorrow
 * Morgan_WMFresearchShowcase04162014_slides.pdf)]] by Jonathan Morgan -- in this talk I'll give an overview of some research on English Wikipedia Wikiprojects: what kind of work they do, how they do it, and how they have changed over time. 


 * Visualizing Wikipedia Communities using Gephi
 * by Haitham Shammaa -- I will introduce Gephi as a tool for generating a visualized representation of Wikimedia projects communities. Gephi is an open-source network analysis and visualization software, and is utilized to generate graphs that represent users and the interaction among them based on the frequency they send messages to each other on their talk pages.

 * Metrics standardization
 * Metrics Standardization - Wikimedia Research & Data showcase - March 2014.pdfby Dario Taraborelli -- In this talk I'll present the most recent updates on our work on metrics standardization and give a teaser of the Editor Engagement Vital Signs project. 


 * Wikipedia: maintaining production efficiency
 * Maintaining_production_efficiency_(March,_2014).pdfby Aaron Halfaker -- In Halfaker et al. (2013) we present data that show that several changes the Wikipedia community made to manage quality and consistency in the face of a massive growth in participation have ironically crippled the very growth they were designed to manage. Specifically, the restrictiveness of the encyclopedia's primary quality control mechanism and the algorithmic tools used to reject contributions are implicated as key causes of decreased newcomer retention.

 * Mobile session times
 * Mobile_sessions_presentation_(Feb_2014).pdf by Oliver Keyes -- A prerequisite to many pieces of interesting reader research is being able to accurately identify the length of users' 'sessions'. I will explain one potential way of doing it, how I've applied it to mobile readers, and what research this opens up. (slides, read more)


 * Wikipedia article creation research
 * Wikipedia article creation (Nov, 2013).pdf by Aaron Halfaker -- A brief overview of research examining trends in newcomer article creation across 10 languages with a focus on English and German Wikipedias.  In wikis where anonymous users can create articles, their articles are less likely to be deleted than articles created by newly registered editors.  An in-depth analysis of Articles for Creation (AfC) suggests that while AfC's process seems to result in the publication of high quality articles, it also dramatically reduces the rate at which good new articles are published.

 * IP reliability tracking: by Oliver Keyes
 * The Wikipedia Adventure, quantitative and qualitative results from the pilot: by Jake Orlowitz (User:Ocaasi) We made a 7 mission gamified interactive onboarding tutorial to teach people how to edit Wikipedia in 1 hour. The journey involves badges, barnstars, challenges, and simulated interaction throughout a realistic quest to edit the article Earth. Game dynamics were used to create a sense of understanding, belonging, deep value identification, and technical proficiency. The use of games in open source and free culture online communities has great potential to drive participation. This talk will share the inspiration for taking a gamified approach, a review of the design highlights, and a discussion of quantitative and qualitative data and survey analysis. (slides, read more)

 * On the nature of Anonymous Editors
 * Anonymous_editors_-_WMF_R%26D_showcase_(Dec._2013).pdf by Aaron Halfaker -- A brief discussion & critique of the use of the term "anonymous" to refer to IP editors and a presentation of research results that suggest that newly registered users who edit anonymous right before registering their account are highly productive.
