It's great that it's possible to use the POS analysis of LanguageTool when creating new rules. But the analysis itself is far from perfect. If I enter a sentence like
Zwei Putzfrauen wurde der Regenschirm gestohlen.
the POS tagger does not know if “Putzfrauen” is an accusative, dative, genitive or nominative plural of the lemma "Putzfrau". This leads to the problem that the gender neutral alternative "Reinigungskraft" is suggested in the wrong case (accusative instead of dative). Additionally the tagger thinks that "Regenschirm" is the nominative case of the lemma but in this case it's the accusative (maybe it generally has a problem with sentences that are missing a subject?).
So my question is: Is there a possibility to improve the POS analysis?
