Question

我想使用pyner库在python中使用Stanford NER。这是一个基本的代码片段。

import ner 
tagger = ner.HttpNER(host='localhost', port=80)
tagger.get_entities("University of California is located in California, United States")

当我在我的本地python控制台（IDLE）上运行它时。它应该给我这样的输出

  {'LOCATION': ['California', 'United States'],
 'ORGANIZATION': ['University of California']}

但是当我执行此操作时，它显示为空括号。我实际上是新手。

我可以使用以下方式在套接字模式下运行stanford-ner服务器：

java -mx1000m -cp stanford-ner.jar edu.stanford.nlp.ie.NERServer \
    -loadClassifier classifiers/english.muc.7class.distsim.crf.ser.gz \
    -port 8080 -outputFormat inlineXML

并从命令行接收以下输出：

Loading classifier from 
/Users/roneill/stanford-ner-2012-11-11/classifiers/english.muc.7class.distsim.crf.ser.gz 
... done [1.7 sec].

然后在python repl中：

Python 2.7.2 (default, Jun 20 2012, 16:23:33) 
[GCC 4.2.1 Compatible Apple Clang 4.0 (tags/Apple/clang-418.0.60)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import ner
>>> tagger = ner.SocketNER(host='localhost', port=8080)
>>> tagger.get_entities("University of California is located in California, United States")
{'ORGANIZATION': ['University of California'], 'LOCATION': ['California', 'United States']}

我如何使用斯坦福NER（命名实体识别器）的python接口？
