使用Stanford Word Segmenter and Stanford Named Entity Recognizer (NER)实现英文命名实体识别

http://blog.csdn.net/shijiebei2009/article/details/42525091
2016/1/11通过阅读上面的博客，学习了如何使用Stanford Word Segmenter and Stanford Named Entity Recognizer (NER)实现英文命名实体识别，为了把这些好的资源保存，特意写了这个博客，我弄的是英文文本，下面代码稍有改动，真的感觉大牛无处不在，感恩大牛们的资源，让我能不断学习。

一、分词介绍
http://nlp.stanford.edu/software/segmenter.shtml
斯坦福大学的分词器，该系统需要JDK 1.8+，从上面链接中下载stanford-segmenter-2014-10-26，解压之后，如下图所示

进入data目录，其中有两个gz压缩文件，分别是ctb.gz和pku.gz.
其中 CTB：宾州大学的中国树库训练资料 ,
PKU：中国北京大学提供的训练资料。
当然了，你也可以自己训练，一个训练的例子可以在这里面看http://nlp.stanford.edu/software/trainSegmenter-20080521.tar.gz

二、NER介绍
http://nlp.stanford.edu/software/CRF-NER.shtml

斯坦福NER是采用Java实现，可以识别出（PERSON，ORGANIZATION，LOCATION），使用本软件发表的研究成果需引用下述论文：

Jenny Rose Finkel, Trond Grenager, and Christopher Manning. 2005. Incorporating Non-local Information into Information Extraction Systems by Gibbs Sampling. Proceedings of the 43nd Annual Meeting of the Association for Computational Linguistics (ACL 2005), pp. 363-370.

下载地址在：
http://nlp.stanford.edu/~manning/papers/gibbscrf3.pdf
在NER页面可以下载到两个压缩文件，分别是stanford-ner-2014-10-26和stanford-ner-2012-11-11-chinese

将两个文件解压可看到,默认NER可以用来处理英文，如果需要处理中文要另外处理。

Included with Stanford NER are a 4 class model trained for CoNLL, a 7 class model trained for MUC, and a 3 class model trained on both data sets for the intersection of those class sets.
3 class: Location, Person, Organization
4 class: Location, Person, Organization, Misc
7 class: Time, Location, Organization, Person, Money, Percent, Date
如上图可以看到针对英文提供了3class、4class、7class
但是中文并没有，这是一个在线演示的地址，可以去瞧瞧 ,http://nlp.stanford.edu:8080/ner/

三、分词和NER使用

在Eclipse中新建一个Java Project，将data目录拷贝到项目根路径下，再把stanford-ner-2012-11-11-chinese解压的内容全部拷贝到classifiers文件夹下，将stanford-segmenter-3.5.0加入到classpath之中，将classifiers文件夹拷贝到项目根目录，将stanford-ner-3.5.0.jar和stanford-ner.jar加入到classpath中。最后，去http://nlp.stanford.edu/software/corenlp.shtml下载stanford-corenlp-full-2014-10-31，将解压之后的stanford-corenlp-3.5.0也加入到classpath之中。最后的Eclipse中结构如下：

根据
We also provide Chinese models built from the Ontonotes Chinese named entity data. There are two models, one using distributional similarity clusters and one without. These are designed to be run on word-segmented Chinese. So, if you want to use these on normal Chinese text, you will first need to run Stanford Word Segmenter or some other Chinese word segmenter, and then run NER on the output of that!
Chinese NER
这段说明，很清晰，需要将中文分词的结果作为NER的输入，然后才能识别出NER来。
同时便于测试，本Demo使用Junit-4.4.jar，下面开始上代码
