Text Classification in scikit-learn¶ First, let’s get the corpus we will be using, which is included in NLTK. You will need NLTK and Scikit-learn (as well as their dependencies, in particular scipy and numpy) to run this code. In [1]: import nltk nltk.download(“reuters”) # if necessary from nltk.corpus import reuters [nltk_data] Downloading package reuters to /Users/jason/nltk_data…
