Since the Tagger class loads the binary dictionary at initialization, it is recommended to reuse the instance.

tagger = Suika::Tagger.new

sentences.each do |sentence|
  result = tagger.parse(sentence)

  # ...
end

Test

Suika was able to parse all sentences in the Livedoor news corpus without any error.

require 'suika'

tagger = Suika::Tagger.new

Dir.glob('ldcc-20140209/text/*/*.txt').each do |filename|
  File.foreach(filename) do |sentence|
    sentence.strip!
    puts tagger.parse(sentence) unless sentence.empty?
  end
end

Respect

  • Taku Kudo is the author of MeCab that is the most famous morphological analyzer in Japan. MeCab is one of the great software in natural language processing. Suika is created with reference to the book on morphological analysis written by Dr. Kudo.
  • Tomoko Uchida is the author of Janome that is a Japanese morphological analysis engine written in pure Python. Suika is heavily influenced by Janome's idea to include the built-in dictionary and language model. Janome, a morphological analyzer written in scripting language, gives me the courage to develop Suika.
