mecab.js

Node.js bindings for mecab (japanese word boundaries) The original project: http://mecab.googlecode.com/svn/trunk/mecab/doc/index.html

Installation

If you read Japanese, follow the instructions on http://mecab.googlecode.com/svn/trunk/mecab/doc/index.html, do not forget to compile mecab-ipadic with unicode support.

For the rest of us:

Get the latest version of mecab from http://mecab.googlecode.com/svn/trunk/mecab/doc/index.html#download

tar zxfv mecab-X.X.tar.gz
cd mecab-X.X
./configure 
make
make check
sudo make install

Get the latest version of mecab-ipadic (a dictionary) from the same site. There are other dictinaries, but I haven't tried them yet.

tar zxfv mecab-ipadic-2.7.0-XXXX.tar.gz
mecab-ipadic-2.7.0-XXXX
./configure --with-charset=utf-8
make
sudo make install

Make sure you have a recent version of Node.js installed.

git clone https://github.com/simedw/mecab.js.git
cd mecab.js
npm install

Usage

mecab  = require 'mecab'
input  = '犬が猫を追いかけていました。'

parser = new mecab.MeCab()
parser.parse input, (error, result) ->
  throw error if error
  console.log result

Gives the following output

[ '犬', 'が', '猫', 'を', '追いかけ', 'て', 'い', 'まし', 'た', '。' ]

Todo

  • Return information for each word segment (if it's an adjective, verb etc)
  • Make the result included the second best result as well
