scikit-learn has an implementation of multinomial naive Bayes, which is the right variant of naive Bayes in this situation. A support vector machine (SVM) would probably work better, though. As Ken pointed out in the comments, NLTK has a nice wrapper for scikit-learn classifiers. Modified from the docs, here’s a somewhat complicated one that does … Read more
To save: import pickle f = open(‘my_classifier.pickle’, ‘wb’) pickle.dump(classifier, f) f.close() To load later: import pickle f = open(‘my_classifier.pickle’, ‘rb’) classifier = pickle.load(f) f.close()
The accepted answer has many elements of k-NN (k-nearest neighbors), a different algorithm. Both k-NN and NaiveBayes are classification algorithms. Conceptually, k-NN uses the idea of “nearness” to classify new entities. In k-NN ‘nearness’ is modeled with ideas such as Euclidean Distance or Cosine Distance. By contrast, in NaiveBayes, the concept of ‘probability’ is used … Read more
