Extracting lack of information on Wikipedia by comparing multilingual articles

Wikipedia has multilingual articles, the information of which differs, even for articles on the same topic. As described in this paper, we propose a system to extract and present lack of information of one language on Wikipedia by comparing two languages on the Wikipedia. When we compare Wikipedia articles of two languages, the granularity of information between them differs. Therefore, we propose a method of extracting multiple comparison articles using a Wikipedia link graph. The system extracts lack of information that is included in articles in Wikipedia by comparing one base article with other articles that are found using the link graph.
