NLTK和停用词失败#lookuperror [英] NLTK and Stopwords Fail #lookuperror
问题描述
我正在尝试启动一个情绪分析项目，我将使用停用词方法.我进行了一些研究，发现nltk有停用词，但是当我执行命令时会出现错误.
I am trying to start a project of sentiment analysis and I will use the stop words method. I made some research and I found that nltk have stopwords but when I execute the command there is an error.
下面是我的操作，以便了解nltk所使用的单词(例如，您可能在此处找到的内容 http://www.nltk.org/book/ch02.html 在第4.1节中):
What I do is the following, in order to know which are the words that nltk use (like what you may found here http://www.nltk.org/book/ch02.html in section4.1):
from nltk.corpus import stopwords
stopwords.words('english')
但是当我按Enter时，我会得到
But when I press enter I obtain

54 except LookupError, e:
55 try: root = nltk.data.find('corpora/%s' % zip_name)
---> 56 except LookupError: raise e

而且，由于这个问题，这样的事情无法正常运行(获得相同的错误):
And, because of this problem things like this cannot run properly (obtaining the same error):
>>> from nltk.corpus import stopwords
>>> stop = stopwords.words('english')
>>> sentence = "this is a foo bar sentence"
>>> print [i for i in sentence.split() if i not in stop]
您知道可能是什么问题吗?我必须使用西班牙语单词，您推荐另一种方法吗?我还认为将Goslate包与英语数据集一起使用
Do you know what may be problem? I must use words in Spanish, do you recomend another method? I also thought using Goslate package with datasets in english
感谢阅读！
P.D .:我使用Ananconda

推荐答案
您的计算机上似乎没有停用词语料库.
You don't seem to have the stopwords corpus on your computer.
您需要启动NLTK下载器并下载所需的所有数据.
You need to start the NLTK Downloader and download all the data you need.
打开Python控制台并执行以下操作:
Open a Python console and do the following:
>>> import nltk
>>> nltk.download()
showing info http://nltk.github.com/nltk_data/
在打开的GUI窗口中，只需按下载"按钮以下载所有语料库，或转到公司"标签，仅下载您需要/想要的那些.
In the GUI window that opens simply press the 'Download' button to download all corpora or go to the 'Corpora' tab and only download the ones you need/want.
