Wikipedia: how to find the necessary information of the highest quality?

Wikipedia currently has more than 50 million articles in more than 300 languages. Despite its popularity, this online encyclopaedia is often criticized for its low quality of information. However, depending on the topic and language version, valuable content can be found there. Using machine learning algorithms and semantic representations of Wikipedia in other knowledge bases, this information can be automatically compared in different language versions and the best (of the highest quality) can be selected. The workshop presented WikiRank, a tool that allows to evaluate and compare the quality of Wikipedia articles in different language versions and to identify the most popular articles in the world about people, films, games, companies, cars and other objects.
