Natto2classifier

Welcome to your new gem! In this directory, you'll find the files you need to be able to package up your Ruby library into a gem. Put your Ruby code in the file lib/natto2classifier. To experiment with that code, run bin/console for an interactive prompt.

Add this line to your application's Gemfile:

gem 'natto2classifier'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install natto2classifier

bayes = Natto2classifier::Bayes.new '朝食', '夕食'
bayes.train '朝食', '今日の朝食は納豆だ'
bayes.train '夕食', '今日の夕食は湯豆腐だ'
bayes.classify '納豆はいつも朝食べている' #=> '朝食'

lsi = Natto2classifier::LSI.new
lsi.add_item '今日の朝食は納豆だ', '朝食'
lsi.add_item '今日の夕食は湯豆腐だ', '夕食'
lsi.classify '納豆はいつも朝食べている' #=> '朝食'
lsi.find_related '納豆はいつも朝食べている' #=> ['今日 キョウ の ノ 朝食 チョウショク は ハ 納豆 ナットウ だ ダ', '今日 キョウ の ノ 夕食 ユウショク は ハ 湯豆腐 ユドウフ だ ダ']

sample_data = CSV.read('./data/train.csv')
bayes = Natto2classifier::Bayes.new '朝食', '夕食'
cross_validate(bayes, sample_data) #=> report...

test_data, training_data = sample_data.partition.with_index { |_, i| (i % 2).zero? }
validate(bayes, training_data, test_data) #=> {"夕食"=>{"夕食"=>3, "朝食"=>0}, "朝食"=>{"夕食"=>...}}

After checking out the repo, run bin/setup to install dependencies. Then, run rake test to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.
