15. A system comprising: a memory device configured to store a natural language processing (NLP) management module; a processing device in communication with the memory device, the processing device configured to execute the NLP management module stored in the memory device to manage NLP model training, the managing comprising: providing an unlabeled corpus of multilingual documents that span a plurality of target languages; training a multilingual embedding on the corpus of multilingual documents as input training data, the multilingual embedding being generalized across the target languages by modifying the input training data and/or transforming multilingual dictionaries into constraints in an underlying optimization problem; training an NLP model on training data for a first language of the target languages, using word embeddings of the trained multilingual embedding as features; and applying the trained NLP model on data from a second of the target languages, the first and second languages being different.
