sorry i didn't finish writing when i pushed send. Actually my types are Lemma (with feature lemma), Term (with features lemma and postag) and POSTag (with feature postag) and i was learning rules with the feature lemma only.
And for this: this.activeFeatures = new ArrayList<String>(tokenAnnotation.getFeatureMap().keySet()); I didn't get your point. In the featureMap there are only features we want to consider, so what is the problem? For types not concerned, this map is empty anyway. Best, Sondes
