我刚开始使用词性标注器,而且我面临很多问题。什么是NLTK POS tagger要我下载?
我开始词性标注下列要求:
import nltk
text=nltk.word_tokenize("We are going out.Just you and me.")
当我想打印'text'
,会发生以下情况:
print nltk.pos_tag(text)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "F:\Python26\lib\site-packages\nltk\tag\__init__.py", line 63, in pos_tag
tagger = nltk.data.load(_POS_TAGGER)
File "F:\Python26\lib\site-packages\nltk\data.py", line 594, in load
resource_val = pickle.load(_open(resource_url))
File "F:\Python26\lib\site-packages\nltk\data.py", line 673, in _open
return find(path).open()
File "F:\Python26\lib\site-packages\nltk\data.py", line 455, in find
raise LookupError(resource_not_found)`
LookupError:

我用nltk.download()
,但没有奏效。
为什么您要将所有文本加粗?这实际上没有必要。另外,请发布一个最小但完整的例子来说明你的错误。 – 2011-12-21 13:22:34
在那里,我为你清理它。请以此为例来说明如何格式化未来的问题。 – 2011-12-21 13:26:40
