get tfidf score for a sentence
>>> from sklearn.feature_extraction.text import TfidfVectorizer >>> corpus = [ ... 'This is the first document.', ... 'This document is the second document.', ... 'And this is the third one.', ... 'Is this the first document?', ... ] >>> vectorizer = TfidfVectorizer() >>> X = vectorizer.fit_transform(corpus) >>> print(vectorizer.get_feature_names()) ['and', 'document', 'first', 'is', 'one', 'second', 'the', 'third', 'this'] >>> print(X.shape) (4, 9)
