ISO Java implementation of NLP tasks: normalization, IBM Model 1 and Okapi BM Ask Question. up vote 1 down vote favorite. I've written a prototype in Python that uses the NLTK package to perform 3 NLP tasks: text normalization (split text into words, remove punctuation and other crud, convert words to base forms) train and use IBM. Thanks @ZiyaoWei for highlight the mistake in the IBM Model 1 algorithm documentation.. Just to validate that the fix is right. The original documentation states: In IBM Model 1, word order is ignored for simplicity. Thus, the following two alignments are equally likely. In Python, I'm using NLTK's alignment module to create word alignments between parallel texts. Aligning bitexts can be a time-consuming process, especially when done over considerable corpora. It would be nice to do alignments in batch one day and use those alignments later on.
