In an approach for evaluating performance of machine translation, a processor receives a first document in a source language. A processor translates the first document in the source language to a second document in a target language, based, at least in part, on a first quantity of information. A processor evaluates the second document in the target language, based, at least, on one or more aspects of the translation. A processor determines, based, at least in part, on the evaluation, the second document in the target language meets a predetermined threshold.
