Hello Daniel, I'm new to the list, but as i also work with german language and POS-tags, i want to give my 2 cent: Please consider that capitalisation is probably one of the features used to determine the correct tag.
So if you have a noun like "Sonne" it should not begin with a small "s". Most NLP tools are not very robust for this kind of errors (and so sometimes out of the box not a good match for e.g. social media, because they are trained on news which mostly have correct spelling).

That would help me a lot. Or can you recommend someone who is experienced? I m not into computer linguistic in detail. In past, i wrote my own algorithms, compined them with stemming and levinstein but openNLP would offer a totally different approach - i guess. Rright now, i just need someone who pushes me into the right direction.
