we are currently in process of deciding whether LanguageTool is something we should use in our teaching and provide our students with. One key argument for us would be if it was possible to form rules to warn our students when getting POS order wrong (i.e. putting prepositional phrases outside the German "Verblammer" of auxilary and inflected verb at the very end of the sentence, see http://www.schrijven.ugent.be/duits/verbklammern).
German sentences such as
"Peter wurde intensiv hofiert von Petra im Sommer."
are correct under certain oral discourse conditions, but are mostly regarded as unacceptible, especially in written German.
The correct version should be:
"Peter wurde im Sommer intensiv von Petra hofiert."
From what I read in the wiki, I would guess that POS tags are the key to the solution, but I'm not sure whether I already understand them ... I'd really appreciate some advice how we could write a rule or a set of rules that would warn our students when they are getting these things wrong.
