6行代码 超级简单 语言情感分析 - 使用Python的vaderSentiment库实现

废话不多说，上码！

pip install vaderSentiment

from vaderSentiment.vaderSentiment import SentimentIntensityAnalyzer
sentences = ['I like you just so so','I like you a little','I like you','I like you very much','I hate you just so so','I hate you a little','I hate you','I hate you very much',]
analyzer = SentimentIntensityAnalyzer()
for sentence in sentences:
    vs = analyzer.polarity_scores(sentence)
    print("{:-<65} {}".format(sentence, str(vs)))

输出结果的值为：消极negative、中性neutral、积极positive、复合情绪compound

注：以上代码保存为.py文件即可执行，vaderSentiment只支持英文的文本进行情感分析，不支持中文！不支持中文！不支持中文！
