我正在尝试使用 NLTK 中 Vader 情绪分析的 polarity_scores()，但它给了我错误:
polarity_scores() missing 1 required positional argument: 'text'
我完全是 Python 的初学者。感谢你的帮助!
from nltk.sentiment.vader import SentimentIntensityAnalyzer as sid
sentences=["hello","why is it not working?!"]
for sentence in sentences:
ss = sid.polarity_scores(sentence)
最佳答案
SentimentIntensityAnalyzer 是一个类。您需要初始化 SentimentIntensityAnalyzer 的对象并调用 polarity_scores() 方法。
from nltk.sentiment.vader import SentimentIntensityAnalyzer as SIA
sentences=["hello","why is it not working?!"]
sid = SIA()
for sentence in sentences:
ss = sid.polarity_scores(sentence)
如果您还没有下载词典文件，您可能需要下载
