例如,在Python中可以使用NLTK库的stopwords模块来移除停用词: ```python from nltk.corpus import stopwords stop_words = stopwords.words('english') text = 'This is an example sentence, showing off stop words filtration.' clean_text = ' '.join([word for word in text.split() if word.lower() ...
我是这样使用countVectorizer的: from sklearn.feature_extraction.text import CountVectorizer vectorizer = CountVectorizer(max_features=200, min_df=2, max_df=0.7, stop_words=stopwords.words('arabic')) X = vectorizer.fit_transform(X).toarray() 现在这段代码将字符串转换为二进制,然后我将训练...
