nimono

nimono is an interface of CaboCha for MRI Ruby and JRuby, and parsing Japanese sentences using the library. It depends on the CaboCha library so the library will have to install first.

Requirements

nimono requires the following:

• CaboCha 0.69
• CaboCha requires CRF++, MeCab and either of the following dictionaries.
• mecab-ipadic, mecab-jumandic, unidic. For further information please refer to the MeCab.
• ffi 1.9.0 or higher

Installation

Install it as:

$ gem install nimono

Usage

Create an instance of Nimono::Cabocha and parse the sentence. By default, the result is outpeuuted by displaying Sumple Tree.

require 'nimono'

nc = Nimono::Cabocha.new
puts nc.parse('太郎は花子が読んでいる本を次郎に渡した')
    太郎は---------D
      花子が-D     |
    読んでいる-D   |
            本を---D
            次郎に-D
              渡した
EOS

Example of analyzing dependency:

require 'nimono'

nc = Nimono::Cabocha.new('-n1')
nc.parse('太郎は花子が読んでいる本を次郎に渡した')

nc.chunks.each do |chunk|
  puts "* #{chunk.id} #{chunk.link}D #{chunk.head_pos}/#{chunk.func_pos} #{'%6f' % chunk.score}"
  chunk.tokens.each do |token|
    puts "#{token.surface}\t#{token.feature}\t#{token.ne}"
  end
end
