NattoWrap

NattoWrap is lightweight wrapper library for using natto. It is useful for extracting nouns, converting to MeCabModels and so on from sentences. To experiment with that code, run bin/console for an interactive prompt.

original natto library is at https://github.com/buruzaemon/natto

Add this line to your application's Gemfile:

gem 'natto_wrap'

And then execute:

$ bundle

Or install it yourself as:

$ gem install natto_wrap

require 'natto_wrap'

puts NattoWrap::MeCabModel.to_reading('今日は晴です')

キョウハハレデス


puts NattoWrap::MeCabModel.extract_nouns('今日は晴です').map(&:word)

今日
晴


models = NattoWrap::MeCabModel.convert_model('今日は晴です')
puts models.map { |model| model.to_csv.join(',') }
