This month:
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.
Active Editors' Survival Models
by Leila Zia -- I will talk about first results in building prediction models for active
editors' survival. A sample of such prediction models, their performance, and the
important variables in predicting survival will be presented.
