Pyner 空字典

Question

我正在使用Stanford Named Entity Recognizer (NER). The code can be found at Pyner Code

的python接口

import ner


if __name__ == "__main__": 
  tagger = ner.HttpNER(host='localhost', port=8080)
  print tagger.get_entities("University of California is located in California, United States")
  print tagger.json_entities("Alice went to the Museum of Natural History.")

假设的输出：

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

'{"ORGANIZATION": ["Museum of Natural History"], "PERSON": ["Alice"]}'

问题：为什么我得到空集？

我尝试了以下 solution-Whosebug 但没有成功我收到以下异常：

Exception in thread "main" java.net.BindException: Address already in use
        at java.net.PlainSocketImpl.socketBind(Native Method)
        at java.net.AbstractPlainSocketImpl.bind(AbstractPlainSocketImpl.java:376)

Answer 1

首先运行套接字模式下的 stanford-ner 服务器使用：

java-mx256m-cp stanford-ner.jaredu.stanford.nlp.ie.NERServer\ -loadClassifier classifiers/english.muc.7class.distsim.crf.ser.gz \ -port 8081 -outputFormat inlineXML.

将代码保存在 windows 批处理文件中，然后运行在命令提示符中保存。

您的端口 8080 有问题。这就是我将端口更改为 8081 的原因。在服务器获得运行ning 后，输入您的 python 代码 -

>>>import ner
>>>tagger = ner.SocketNER(host='localhost', port=8081)
>>>tagger.get_entities("University of California is located in California, United States")
