Scikit-learn text feature extractors
KTT can provide facilities for using most Scikit-learn text feature extractors with your classifiers. Two of the bundled models also make use of Scikit-learn’s TfidfVectorizer facilities.
At present, KTT comes bundled with one predesigned Scikit-learn preprocessor, the SnowballStemmerPreprocessor. As its name implies, this preprocessor stems non-stopword tokens in your text to reduce the amount of vocabulary your encoder has to learn. Its stop words dictionary is powered by NLTK.
