Abstract: Systems and methods for using automated translation and other statistical methods to convert a classifier in one language to another language are provided. In one embodiment of the invention, a method preferably includes marking target language examples of passages of text in order to obtain an initial classifier in the target language, re-classifying a plurality of target language examples in the initial classifier, and then questioning—i.e., determining the validity—of the marking used to obtain the initial classifier. Preferably, the questioning is based on the re-classifying. Then, preferably following the questioning, the method isolates a high-quality set of target examples based on the results of the questioning. Finally, the method uses the high-quality set of target examples to prepare a high-quality classifier in the target language.
