Dynamics of Conflicts in Wikipedia PLoS ONE English June 2012 In this work we study the dynamical features of editorial wars in Wikipedia (WP). Based on our previously established algorithm, we build up samples of controversial and peaceful articles and analyze the temporal characteristics of the activity in these samples. On short time scales, we show that there is a clear correspondence between conflict and burstiness of activity patterns, and that memory effects play an important role in controversies. On long time scales, we identify three distinct developmental patterns for the overall behavior of the articles. We are able to distinguish cases eventually leading to consensus from those cases where a compromise is far from achievable. Finally, we analyze discussion networks and conclude that edit wars are mainly fought by few editors only. 44 1
A practical approach to language complexity: a Wikipedia case study Submitted to PLoS ONE English 2012 In this paper we present statistical analysis of English texts from Wikipedia (WP). We try to address the issue of language complexity empirically by comparing samples of the main English WP (Main) and the simple English WP (Simple). Simple is supposed to use a more simplified language with a limited vocabulary, and editors are explicitly requested to follow this guideline, yet in practice the vocabulary richness of both samples are at the same level. However, detailed analysis of longer units (n-grams rather than words alone) shows that the language of Simple is indeed less complex than that of Main. Comparing the two language varieties by the Gunning readability index supports this conclusion. We also report on the topical dependence of language complexity, e.g. that the language is more advanced in conceptual articles compared to person-based (biographical) and object-based articles. Finally, we investigate the relation between conflict and language complexity by analysing the content of the talk pages associated to controversial and peacefully developing articles, concluding that controversy has the effect of reducing language complexity. 0 0

WebSci Conference English 2011 We present a new, eficient method for automatically detecting conict cases and test it on five diferent language Wikipedias. We discuss how the number of edits, reverts, the length of discussions deviate in such pages from those following the general workow. 4 2
Edit wars in Wikipedia IEEE Third International Conference on Social Computing English 2011 We present a new, efficient method for automatically detecting severe conflicts `edit wars' in Wikipedia and evaluate this method on six different language WPs. We discuss how the number of edits, reverts, the length of discussions, the burstiness of edits and reverts deviate in such pages from those following the general workflow, and argue that earlier work has significantly over-estimated the contentiousness of the Wikipedia editing process. 9 2
