English: In Wikipedia, articles about various topics can be created and edited independently in each language version. Therefore, quality of information about the same topic depends on language. Any interested user can improve an article and that improvement may depend on popularity of the article. The goal of the presentation is to show how we can measure quality and popularity of the Wikipedia articles to find what topics are best represented in different language versions of Wikipedia using over 10 million categories and over 26 million links between them. Additionally data from DBpedia and Wikidata were used. Different quality and popularity measures can be used to create various rankings of Wikipedia articles in local and global scale, as well as to build profile of each article - as an example WikiRank use case is described.
