An OCaml binding of MeCab, a part-of-speech and morphological analyzer.

MeCab is a open-sourced part-of-speech and morphological analyzer independent from languages, dictionaries, and corpuses, developed by a joint project team of
Graduate School of Informatics in Kyoto University and
NTT Communication Science Laboratories.
MeCab is almost faster than ChaSen, Juman, and KAKASHI.
The official documentation (written in Japanese) is published at MeCab: Yet Another Part-of-Speech and Morphological Analyzer, and English-translated version is at MeCab English Documentation.
