I haven't tried it yet, but Spacy has a guide[1] for adding a new languages to their python NLP framework. Maybe it can be of use to you.

This is supervised algorithm, it requires that you annotate a lot of existing text so that the algorithm knows how to annotate "new" sentences.

It statistic based.
