I uploaded on slideshare the presentation I gave time ago at Wikisym 2012. It is embedded below. There is a comparison of Points of View across different wikis (such as ecured.cu, the Cuban government official wiki, and Conservapedia, Anarchopedia, veganpedia, …) and a comparisons of the same page across different language Wikipedias thanks to Manypedia (such as “List of controversial issues” in English, Chinese and Catalan Wikipedia, “Human rights in the United States” in English and Chinese, “Osama Bin Laden” in English and Arabic, “Vietnam War” in English and Vietnamese, “Northern Cyprus” in Turkish, Greek and English Wikipedia, “Underwear” in English and Arabic)
Manypedia is online at http://www.manypedia.com.
The paper is at http://www.gnuband.org/papers/manypedia-comparing-language-points-of-view-of-wikipedia-communities/. If you like Manypedia and the paper, please cite it. Thanks!
