Abstract: Wikipedia's brilliance and curse is that any user
can edit any of the encyclopedia entries. We introduce the notion of the impact of an edit, measured by the number of times the edited version is viewed. Using several datasets, including recent logs of all article views, we show that an overwhelming majority of the viewed words were written by frequent editors and that this majority is increasing. Similarly, using the same impact measure, we show that the probability of a typical article view being damaged is small but increasing, and we present empirically grounded classes of damage. Finally, we make policy recommendations for Wikipedia and other wikis in light of these findings.
Really interesting metrics for measuring the actual impact of errors in WikiPedia!
And I am looking forward to seeing your GeoWiki talk at WikiSym. Guys, this is only one of many excellent talks that will be given at WikiSym. I invite you all to attend it in Montreal this month:
