这是我的代码和错误信息:
>>> from nltk.tag.stanford import StanfordTagger
>>> st = StanfordTagger('bidirection-distsim-wsj-0-18.tagger')
Traceback (most recent call last):

raise LookupError('\n\n%s\n%s\n%s' % (div, msg, div))
LookupError:

我该如何解决?我真的很想在 Python 中使用 stanford tagger 谢谢!
最佳答案
from nltk.tag.stanford import POSTagger
st = POSTagger( < path to tagger >, < path to stanford NLP package/stanford-postagger.jar >)
包括两个参数的完整路径。
如果可行,那就试试例句
st.tag('What is the airspeed of an unladen swallow ?'.split())
检查是否将 Stanford Parser 路径添加到 CLASSPATH
环境变量
export CLASSPATH = {CLASSPATH}: < path to stanford NLP package >
这应该有效。
