If you’re a NLP enthusiast, you’re going to love this section. It lacked a scientific approach and was detached from language itself. Here’s what a model usually does: it describes how the modelled process creates data. Le NLP fut développé autour de la recherche linguistique et des sciences cognitives, la psychologie, la biologie et les mathématiques. With these scripts, you can do the following things without writing a single line of code: train NLTK based models; evaluate pickled models against a corpus; analyze a corpus; These scripts are Python 2 & 3 compatible and work with NLTK 2.0.4 and higher.
