Since German has arbitrary composita, a purely lookup-based lemmatiser will often fail because of OOV words. But in many cases a guess that is better than nothing at all could be to combine the prefix with the lemma of a known suffix, e.g: lemma("Mithelferinnen" ) = "Mit"+lemma("Helferinnen").
Are there any plans to add support for composita?
