For those who couldn’t attend Wikimania, the annual international Wikimedia conference, this panel of top contributors to the wiki community reviews some of the latest developments, lessons learned, and what to expect from Wikimedia in the future.

Adina Levin of SocialText leads a panel that includes Wikimedia executives and other noted wiki experts as they share highlights from Wikimania 2009. The panelists discuss a project that would allow Wikimedia to be more usable for contributers, opportunities to help Wikimedia move forward, and the latest wiki trends.

Yahoo!'s Micah Alpern describes the culture of Wikimania. 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. Whether you use wikis for reference, contribute to wikis at work, use other kinds of user-contributed media, or participate in open-source communities, you'll learn a lot from these experts.

    • 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 rates Were high cost and scaled up with traffic
    • Answers Community Moderation To address these challenges: challenges: Deployed a new Community Moderation system Empowered trusted Answers users to help moderate content by allowing their report abuse actions to automatically delete content. content. Illustration by Bryce Glass System didn’t reveal reputation scores to users, didn’ users, Encouraged them to report accurately so they could gain more community influence. influence.

    • 1.  What’re the Global Activity level patterns? 2.  What’re activity patterns by Editor Classes? 3.  Are the Population Sizes stable? Analysis of Population by Editor Class

    • Monthly Edits by Editor Class (in thousands)
    •   Undoing the effects of one or more edits –  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”
    • Monthly Ratio of Reverted Edits
    •   Increased resistance from the Wikipedia community to activities by occasional editors   Disparity of treatment of edits –  Occasional editors have been reverted in a higher rate Photo: http://lianza2009.wordpress.com/
    • 1.  What’re the Global Activity level patterns? 2.  What’re activity patterns by Editor Classes? 3.  Are the Population Sizes stable? Analysis of Population by Editor Class
    • Monthly Active Editors
    • 1.  What’re the Global Activity level patterns? –  No longer following an exponential growth curve. –  Logistic growth is now a better explanation 2.  What’re activity patterns by Editor Classes? –  Middle class decreasing their proportion of edits –  Different editor classes experience differing resistances 3.  Are the Population Sizes stable? –  Middle class a smaller portion of the pyramid
    •   Exponential growth model –  Growth rate depends on the current N dN = 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
    •   Ecological population growth model –  r, growth rate of the population –  K, carrying capacity (due to resource limitation) dN N = rN(1− ) dt K €
    •   Follows a logistic growth curve New Article
    •   Carrying Capacity as a function of time.
    •   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
    •   Ecological growth model –  r, growth rate of the population –  K, carrying capacity (due to resource limitation)   r-Strategist –  Growth or exploitation dN N –  Less-crowded niches / produce many = rN(1− ) dt K offspring   K-Strategist –  Conservation [Gunderson & Holling 2001] –  Strong competitors in crowded niches / € invest more heavily in fewer offspring
    •   People-ware –  Growing resistance to new content –  Coordination cost and bureaucracy   Knowledge-ware –  Availability of easy topics to write about   Tool-ware –  Quality of tools used by editors and admins
