Can you show me a simple example using http://www.nltk.org/code to determine if a string about a happy or upset mood?

推荐答案

NLTK不能开箱即用，但是如果您正在寻找有关该领域的一些相关研究，请参阅 WEKA 并使用在先前示例中经过训练的多个分类器来确定语言是否令人反感(并且在此方法中使用可调阈值).

NLTK cannot out of the box, but if you are looking for some related research on that area, take a look at this paper on Offensive Language Detection. The same methods could be adapted to detect comments which are not offensive/unoffensive, but instead happy/unhappy. The primary software package being used in this project for text classification is called WEKA and uses multiple classifiers, trained on previous examples, to determine whether language is offensive or not (and in this method uses a tunable threshold).
