I don't remember...if my memory doesn't lie to me,the problem was in the simple dictionary..try with full English

Hello, I am facing this problem too, I traced it in the source code, and it looks like a problem when trying to load a java class. Did changing the language helped solve your problem? I need to load `ar` language only.

[saisubra...@gmail.com]

Hi,

I had to hardcode the language in the src and re-build the jar to make it work.

Regards,
Sai

I solved it by creating a project in Eclipse, adding Wikibrain as maven dep, and writing a main() class that runs the pipeline. Thank you
