Nlpir
A rubygem wrapper of chinese segment tools ICTCLAS2013
Installation
Add this line to your application's Gemfile:
gem 'nlpir'
And then execute:
$ bundle
Or install it yourself as:
$ gem install nlpir
Usage
Nlpir version 0.0.1 just support the *nix OS, and We`ll release it for windows platform in few days.
some DEFINE you may use :
NLPIR_FALSE = 0
NLPIR_TRUE = 1
POS_MAP_NUMBER = 4
ICT_POS_MAP_FIRST = 1 #计算所一级标注集
ICT_POS_MAP_SECOND = 0 #计算所二级标注集
PKU_POS_MAP_SECOND = 2 #北大二级标注集
PKU_POS_MAP_FIRST = 3 #北大一级标注集
POS_SIZE = 40
Result_t = struct ['int start','int length',"char sPOS[#{POS_SIZE}]",'int iPOS',
'int word_ID','int word_type','double weight']
GBK_CODE = 0 #默认支持GBK编码
UTF8_CODE = GBK_CODE + 1 #UTF8编码
BIG5_CODE = GBK_CODE + 2 #BIG5编码
GBK_FANTI_CODE = GBK_CODE + 3 #GBK编码,里面包含繁体字
after you gem install it:
require 'nlpir'
include Nlpir
s = "坚定不移沿着中国特色社会主义道路前进 为全面建成小康社会而奋斗"

if NLPIR_Init(nil, UTF8_CODE ,File.("../", __FILE__))==NLPIR_FALSE
