Note

This library uses clojure.java.shell/sh to access mecab so that you do not need Java JNI bindings. If you want to deploy your application to Saas such as Heroku, you better use kuromoji (Java implementation) instead. But mecab is much faster than kuromoji, so you should use mecab when you process massive data.
