Question

我在NLP项目的win8.1 64x上的Azure Jupyter笔记本上使用Python 3.6。我正在尝试安装Stanford NER Tagger。我下载了Java和所有三个组件

1）stanford-ner-2015-12-09， 2）stanford-parser-full-2018-10-17， 3）stanford-postagger-2015-12-09

并将这三个文件上传到我在Azure Jupyter笔记本上的目录中。为了测试斯坦福大学的NER Tagger，我按照https://pythonprogramming.net/named-entity-recognition-stanford-ner-tagger/

的建议运行了以下代码

# -*- coding: utf-8 -*-

from nltk.tag import StanfordNERTagger
from nltk.tokenize import word_tokenize

st = StanfordNERTagger('/usr/share/stanford-ner/classifiers/english.all.3class.distsim.crf.ser.gz',
                       '/usr/share/stanford-ner/stanford-ner.jar',
                       encoding='utf-8')

text = 'While in France, Christine Lagarde discussed short-term stimulus efforts in a recent interview with the Wall Street Journal.'

tokenized_text = word_tokenize(text)
classified_text = st.tag(tokenized_text)

print(classified_text)

但是我收到以下查找错误，该错误基本上建议在CLASSPATH上设置变量。我之前在Azure Jupyter笔记本上安装了许多软件包，但这是第一次要求设置CLASSPATH环境。我上网浏览了可用的文档，但是很遗憾，到目前为止，没有人针对Azure Jupyter环境解决此问题。感谢您的帮助。
