除了文字对话,我们还可以用Python进行诗歌分析,判断某首唐诗是李白还是杜甫的作品。通过自然语言处理和特征提取,可以实现简单但有效的文本分类。 import jieba from nltk.classify import NaiveBayesClassifier text1 = open(r"libai.txt", "rb").read() list1 = jieba.cut(text1) result1 = "".join(list1) ...
我试图使用NLTK工具包对Twitter上的一部新电影做一些情感分析。当我调用nltk.classify.util.accuracy(classifier, testfeats)时,问题就出现了。以下是代码:importglobfromnltk.classifyimportNaiveBayesClassifierfromnltk.c 浏览4提问于2015-08-10得票数1 回答已采纳 ...
from sklearn.linear_model import LogisticRegression from sklearn.naive_bayes import GaussianNB from sklearn.ensemble import RandomForestClassifier 下面的可视化工具一次只能接受两个特征作为输入,所以我们创建了数组['proline', 'color_intensity']。因为这两个特征在上述利用ELI5分析时,具有最高的特征重要性。 X...
