• A query translation method based on expectation maximization algorithm is proposed. • The method (EM4QT) exploits pseudo-relevant documents in source and target languages. • EM4QT extracts a number of hidden variables for each translation pair. • EM4QT employs an expectation maximization algorithm for estimating the parameters. • EM4QT outperforms competitive baselines in cross-language information retrieval.
