KoNLPy
KoNLPy provides Korean natural language processing tools for Python applications.
About KoNLPy
KoNLPy is a Python package for natural language processing (NLP) of the Korean language. It provides morphological analysis and part-of-speech tagging through several tagger classes: Hannanum, Kkma, Komoran, Mecab, and Okt. The homepage example shows sentence splitting, noun extraction, and part-of-speech tagging with the Kkma class. The documentation is for version 0.6.0.
The documentation includes a user guide, installation instructions for Ubuntu, CentOS, Mac OS, Windows, and Docker, and an API reference. The homepage states that the package is released under GPL v3 or later and asks users who use the code to cite it. The homepage also says KoNLPy is not perfect. The directory record does not list it as open source, so check the license terms before use.
