Task: We have Wikipedia English page and need to retrieve the same page address in Russian.
I know the Semantic Web solution - use simple query to DbPedia, but I am curious whether there are traditional solutions. I have asked the same question in semanticoverflow.com where Toby Inkster suggested to parse http://en.wikipedia.org/wiki/Colugo?action=raw results (there are other languages links in the bottom), but this way is too inefficient. Are there any other ways or DbPedia is the one real option?
Wikipedia has an extensive API, which can provide language links information among others. In this particular case, you're looking for api.php?action=query&prop=langlinks&titles=.... See here for example.
