The newest version!

Phase: npnorm
Input: Token SpaceToken
Options: control = appelt

// there's no apostrophe in Danish possessives; this makes finding NEs a little tough
// e.g. "Aarhus Universitet" is the NP, "Aarhus Universitets" is the possessive 
// (cf. English's Aarhus University's)
// we have a normString feature in DKIE that the gaz uses for lookup
// in this case, if we have a proper noun ending "s", strip the "s"

Rule: PossessiveProperNoun
(
  ({Token.category == NP, Token.string ==~ ".+s"}) |
  ({Token.category == NC, Token.normString ==~ "^[A-Z].*s$"})

{
  // convert the text to replace Danish vowels with diphthong versions
  AnnotationSet tok = bindings.get("possessive");
  Annotation tokAnn = tok.iterator().next();

  FeatureMap tokfeats = (FeatureMap)((SimpleFeatureMapImpl)tokAnn.getFeatures()).clone();


  String normString = (String)tokfeats.get("normString");
  normString = normString.substring(0, normString.length() - 1);
  tokfeats.put("normString", normString);
  tokfeats.put("number", "plural");
