Natural Language Processing with Python Chapter 6.1 由于nltk.FreqDist的排序问题,获取电影文本特征词的代码有些微改动. import nltk from nltk.corpus import movie_reviews as mr def document_features(document,words_features): document_words=set(document) features={} for word in w…

Support Vector Machines for classification To whet your appetite for support vector machines, here’s a quote from machine learning researcher Andrew Ng: “SVMs are among the best (and many believe are indeed the best) ‘off-the-shelf’ supervised learni…
