Sue Gardner, Wikimedia's executive director, covers the foundations priorities and projects. Ed Chi of PARC summarizes his much-discussed research on the slowing growth of Wikipedia, with data, models, and possible explanations. Naoko Komura shows off the achievements of Wikimedia's Usability Project and describes its future plans. Jack Herrick of wikiHow describes his company's efforts to increase contributions to wikis.The broad wiki community is strong, productive, and inventive, and our panelists are a few of the people who help make it a success.

Traditional Moderation Failed As Answers grew traditional moderation methods failed to scale with the community. Manual customer care systems: Had slow response times Treated all abuse reports the same Had high false positive and false negative ratesWere high cost and scaled up with traffic 12. Answers Community Moderation To address these challenges:challenges:Deployed a new Community Moderation systemEmpowered trusted Answers users to help moderate content by allowing their report abuse actions to automatically delete content.content.Illustration by Bryce GlassSystem didnt reveal reputation scores to users, didnusers, Encouraged them to report accurately so they could gain more community influence.influence. 13.

Undoing the effects of one or moreedits The page being restored to a version that existed sometime previously. Reverting may also refer to any action that reverses the actions of other editors. Fighting vandalism This analysis exclude vandalism to model resistance 30. Monthly Ratio of Reverted Edits 31. Increased resistance fromthe Wikipedia community toactivities by occasionaleditors Disparity of treatment of edits Occasional editors have been reverted in a higher ratePhoto: http://lianza2009.wordpress.com/ 32. 1. Whatre the Global Activity level patterns?2. Whatre activity patterns by Editor Classes?3. Are the Population Sizes stable? Analysis of Population by Editor Class 33. Monthly Active Editors 34. 1. Whatre the Global Activity level patterns? No longer following an exponential growth curve. Logistic growth is now a better explanation 2. Whatre activity patterns by Editor Classes? Middle class decreasing their proportion of edits Different editor classes experience differingresistances 3. Are the Population Sizes stable? Middle class a smaller portion of the pyramid 35. Exponential growth model Growth rate depends on the current NdN= r*N dt Preferential Attachment: Edits beget edits The more number of previous edits, the more number of new edits r, growth rate of the population 36. Ecological population growth model r, growth rate of the population K, carrying capacity (due to resource limitation)dNN = rN(1 )dtK 37. Follows a logistic growth curve New Article 38. Carrying Capacity as a function of time. 39. Biological system Competition increases as population hit the limits of the ecology Advantage go to members of the population that have competitive dominance over others Analogy Limited opportunities to make novel contributions Increased patterns of conflict and dominance 40. Ecological growth model r, growth rate of the population K, carrying capacity (due to resource limitation) r-Strategist Growth or exploitation dNN Less-crowded niches / produce many = rN(1 )dtK offspring K-Strategist Conservation[Gunderson & Holling 2001] Strong competitors in crowded niches / invest more heavily in fewer offspring 41.
