The multilingual Wikipedia is the largest existing collaboratively edited encyclopedia, where several translation communities are working towards translating Wikipedia articles. The different language communities are largely independent in terms of policy creation, behavior and community mechanisms. We conducted a case study on the Wikipedia community from a multilingual point of view to better understand community behavior. We also conducted a collaborative Wiki-to-Wiki translation experiment using machine translation tools provided by the Language Grid. Based on the findings of the two studies we designed and developed a multi-language discussion platform for Wikipedia translation communities. In this chapter, we discuss the results of the case study and a laboratory experiment and how the results are applied to facilitate the creation of multilingual collective intelligence in Wikipedia through a multi-language discussion platform.
