python - 斯坦福解析器不适用于 python (Windows 7)

Question

我正在尝试使用此解决方案 Stanford Parser and NLTK ，但它就是行不通。这基本上是从 python 调用斯坦福解析器，然后在 python 中获取输出。解析器是用java编写的。

import os
sentence =  '''I shot an elephant in my pajamas'''
os.popen("echo '"+sentence+"' > ~/stanfordtemp.txt")
parser_out = os.popen("C:/Python27/stanford-parser-2012-11-12/lexparser.sh   ~/stanfordtemp.txt").readlines()
print parser_out

它的工作原理很奇怪，因为当补丁不正确时，它不会报告错误，而当软件的补丁正确时，windows 会询问我要在哪个程序中打开应用程序。在我这样做之后，我仍然像以前一样得到空白输出。也许这与我运行 Windows 7 而不是 Unix 有关？

Update: Tried to install CoreNLP and I cannot ... the file location is accurate.
corenlp = StanfordCoreNLP(corenlp_dir)  # wait a few minutes...

如果您正在寻找使用斯坦福 NLP 解析器，我会采取简单的方法并按照这些说明进行操作。

https://bitbucket.org/torotoki/corenlp-python

将 NLP 解析器作为服务器启动后(注意默认端口为 8080)，打开另一个 python session 并输入以下内容。

刚试了一下，效果很好:-)

import jsonrpclib
import json

server = jsonrpclib.Server("http://localhost:8080")

result = json.loads(server.parse("What is the airspeed velocity of an unladen swallow?"))
print result

这是打印输出:
