# Nlpir_win

A rubygem wrapper of chinese segment tools ICTCLAS2013

Nlpir version 0.0.4 , gem nlpir-0.0.4-x86-mingw32 support '>=ruby2.0.0' on win7.

## Installation

Add this line to your application's Gemfile:

    gem 'nlpir'

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install nlpir

## Usage


some DEFINE you may use :
```ruby

	  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
	
	  #词条结构体 term struct
	  Result_t = struct ['int start','int length',"char  sPOS[#{POS_SIZE}]",'int iPOS',
	  		          'int word_ID','int word_type','double weight']

	  GBK_CODE = 0                              #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，包含繁体字

```

after you gem install it:
