Ask HN: Could you recommend language agnostic NLP tools?

I just build a spell-checker for Wolof, my native language, using some basic rules and a dictionary I managed to put together. I need your help finding open source tools for NLP that are language agnostic or do not require lot of heavy lifting to adapt to a new locale.

Thanks for your help.
