public class GermanSeparatedParticleAnnotator
Annotator to be used for post-processing of German corpora that have been lemmatized and
POS-tagged with the TreeTagger, based on the STTS tagset.
This Annotator deals with German particle verbs. Particle verbs consist of a particle and a stem,
e.g. anfangen = an+fangen There are many usages of German particle verbs where the stem and the
particle are separated, e.g., Wir fangen gleich an. The TreeTagger lemmatizes the verb stem as
"fangen" and the separated particle as "an", the proper verblemma "anfangen" is thus not
available as an annotation. The GermanSeparatedParticleAnnotator replaces the lemma of the stem
of particle-verbs (e.g., fangen) by the proper verb lemma (e.g. anfangen) and leaves the lemma of
the separated particle unchanged.
