All this runs without problems. Web2 Jan 2024 · In NLTK, classifiers are defined using classes that implement the ClassifierI interface, which supports the following operations: self.classify (featureset) self.classify_many (featuresets) self.labels () self.prob_classify (featureset) self.prob_classify_many (featuresets) NLTK defines several classifier classes: …
Web9 Aug 2016 · nltk.NaiveBayesClassifier () is a out-of-box multi-class classifier. So yes you can use this to solve this problem. As per the multi-labelled data, if your labels are a,b,c,d,e,f,g,h,i,j then you have to define label 'b' of a particular document as '0,1,0,0,0,0,0,0,0,0'. Feature extraction is the hardest part of Classification (Machine learning). Webclassifier = nltk.NaiveBayesClassifier.train(training_set) First we just simply are invoking the Naive Bayes classifier, then we go ahead and use .train () to train it all in one line. Easy enough, now it is trained. Next, we can test it: print("Classifier accuracy percent:", (nltk.classify.accuracy(classifier, testing_set))*100)
