在NLTK Python中使用Stanford POS Tagger时出错 [英] Error using Stanford POS Tagger in NLTK Python

问题描述

我正在NLTK中尝试使用Stanford POS Tagger，但无法运行此处给出的示例代码

I am trying to use Stanford POS Tagger in NLTK but I am not able to run the example code given here http://www.nltk.org/api/nltk.tag.html#module-nltk.tag.stanford

import nltk
from nltk.tag.stanford import POSTagger
st = POSTagger(r'english-bidirectional-distim.tagger',r'D:/stanford-postagger/stanford-postagger.jar')
st.tag('What is the airspeed of an unladen swallow?'.split())

我已经将环境变量添加为

I have already added environment variables as

CLASSPATH = D:/stanford-postagger/stanford-postagger.jar
STANFORD_MODELS =  D:/stanford-postagger/models/

这是我不断收到的错误

回溯(最近通话最近一次):

Traceback (most recent call last):

File "D:\pos_stanford.py", line 4, in <module>
    st = POSTagger(r'english-bidirectional-distim.tagger',
         r'D:/stanford-postagger/stanford-postagger.jar')  
... LookupError: NLTK was unable to find the english-bidirectional-distim.tagger file! Use software specific configuration paramaters or set the STANFORD_MODELS environment variable.

一些论坛建议

File "C:\Python27\lib\site-packages\nltk\tag\stanford.py", line 45, in __init__
env_vars=('STANFORD_MODELS'), verbose=verbose)

应进行更改，以使

env_vars=('STANFORD_MODELS',), verbose=verbose)

但是它也不能解决问题. 请帮助我解决这个问题.

but it doesn't solve the problem either. Please Help me in solving this issue.

其他信息: 我在用 Windows 7 64位 Python 2.7 32位 NLTK 2.0

我终于发现我做错了..结果真是个大错.

I finally found out what I did wrong.. it turned out to be a blunder.

Tagger文件名不是'english-bidirectional-distim.tagger' 而是"english-bidirectional-distsim.tagger".

Tagger file name is not 'english-bidirectional-distim.tagger' but 'english-bidirectional-distsim.tagger'.
