We introduce a method that extracts keywords in a language with the help of the other.The method involves estimating preferences for topical keywords and fusing language-specific word statistics.At run-time, we transform parallel articles into word graphs, build crosslingual edges for word statistics integration, and exploit PageRank with word keyness information for keyword extraction.We apply our method to keyword analysis and language learning.Evaluation shows that keyword extraction benefits from cross-language information and language learners benefit from our keywords in reading comprehension test.
