CppjiebaRb

Gem Version

Ruby bindings for Cppjieba. C++11 required. (gcc 4.8+)

The TRIE tree has high memory usage. For default dict, it uses ~120 MB memory.

Installation

Add this line to your application's Gemfile:

gem 'cppjieba_rb', require: false

Or pin a version:

gem 'cppjieba_rb', '~> 0.4.4', require: false

Or install it as:

$ gem install cppjieba_rb

Usage

Segmentation mode is described in cppjieba.

Word segment Usage

Mix Segment mode (HMM with Max Prob, default):

require 'cppjieba_rb'

seg = CppjiebaRb::Segment.new  # equivalent to "CppjiebaRb::Segment.new(mode: :mix)"
words = seg.segment("令狐冲是云计算行业的专家")
# ["令狐冲", "是", "云计算", "行业", "的", "专家"]

The alternative convenient method:

CppjiebaRb.segment('令狐冲是云计算行业的专家', mode: :mix)

HMM or Max probability (mp) Segment mode:

seg = CppjiebaRb::Segment.new(mode: :hmm_ # or  mode: :mp
seg.segment("令狐冲是云计算行业的专家")

Word tagging Usage

require 'cppjieba_rb'

CppjiebaRb.segment_tag("《忍者蝙蝠侠》续集《忍者蝙蝠侠vs极道联盟》发布角色预告片。")
# {"《"=>"x", "忍者"=>"n", "蝙蝠侠"=>"n", "》"=>"x", "续集"=>"v", "vs"=>"eng", "极道"=>"x", "联盟"=>"j", "发布"=>"v", "角色"=>"n", "预告片"=>"n", "。"=>"x"}

Keyword Extractor Usage

require 'cppjieba_rb'

CppjiebaRb.extract_keyword("山西退沙村的明代鼓楼，在今年初被拆掉了。", 5)

# [
#    ["退沙村", 11.739204307083542],
