python调用NLPIR - ICTCLAS2013实现中文分词

环境：win7、VS2008、Python2.7.3

第一步：照着文档[2]将NLPIR库封装成Python的扩展；

第二步：新建一个名为“nlpir_demo”的目录，将第一步最后得到的名为“nlpirpy_ext”的文件夹拷贝到“.../nlpir_demo/”目录下；

第三步：在文档[2]尾部提供的“seg.py”基础上，在“.../nlpir_demo/nlpirpy_ext/”目录下，新建一个名为“C_NLPIR_ICTCLAS2013.py”的文件，内容如下，目的是将NLPIR进一步封装成一个Python类；

 import NLPIR
 import os

 class C_NLPIR_ICTCLAS2013:
     def __init__(self,s_code='GBK'):
         dataurl = os.path.join(os.path.dirname(__file__))
         isinit = 0
         if s_code == 'GBK':
             isinit = NLPIR.NLPIR_Init(dataurl,NLPIR.GBK_CODE)
         elif s_code == 'UTF-8':
             isinit = NLPIR.NLPIR_Init(dataurl,NLPIR.UTF8_CODE)
         elif s_code == 'BIG5':
             isinit = NLPIR.NLPIR_Init(dataurl,NLPIR.BIG5_CODE)
         elif s_code == 'GBK_FANTI':
             isinit = NLPIR.NLPIR_Init(dataurl,NLPIR.GBK_FANTI_CODE)
         if isinit:
             print 'NLPIR 初始化成功'
         else:

 if __name__ == '__main__':

     O_C_NLPIR_ICTCLAS2013 = C_NLPIR_ICTCLAS2013('UTF-8')
     raw_input('\n~!')

第四步：在“.../nlpir_demo/”目录下，新建一个名为“NLPIR_demo.py”的文件，内容如下，试着调用“.../nlpir_demo/nlpirpy_ext/C_NLPIR_ICTCLAS2013.py”中定义的类C_NLPIR_ICTCLAS2013；

 #-*-encoding:utf-8-*-
 from nlpirpy_ext.C_NLPIR_ICTCLAS2013 import C_NLPIR_ICTCLAS2013

 if __name__ == '__main__':

     o_C_NLPIR_ICTCLAS2013 = C_NLPIR_ICTCLAS2013('UTF-8')
     raw_input('\n~!')

     s_test = '1989年春夏之交的政治风波1989年政治风波24小时降雪量24小时降雨量863计划ABC防护训练APEC会议BB机BP机C2系统C3I系统C3系统C4ISR系统C4I系统CCITT建议'
     result = o_C_NLPIR_ICTCLAS2013.stringSeg(s_test)

     raw_input(result)

第五步：执行文件“.../nlpir_demo/NLPIR_demo.py”，即可~！

说明：关于文档[2]中提到的SWIG，可见文档[1]提供了另外两篇文档~！
