o the source given the target sentence.
A commonly used metric for evaluating the success of this process is the BLEU score. Brown et. al. developed IBM's Models 1, 2, 3, 4, and 5, in increasing degree of complexity, for performing the alignment necessary to carry out this process. The decoding step in this process consists of finding the source that best matches the target, and stack-based decoders for this process typically function by generating a hypothesis, extending it, and picking the hypothesis with the highest score. This process generally proceeds by Bayesian expectation maximization methods in which a source sentence is found that maximizes the posterior probability o the source given the target sentence. For 10 points, identify this process in which a computer is given a word or phrase in one language and produces its equivalent in another.
