Hi Carsten, please see https://github.com/m09/readability/blob/master/java/uima-corpus-creator/src/main/java/eu/crydee/readability/uima/corpuscreator/DictCreationPipeline.java#L200
for an example pipeline and https://github.com/m09/readability/blob/master/java/uima-corpus-creator/src/main/java/eu/crydee/readability/uima/corpuscreator/ae/RevisionsFilterAE.java for an example filter. This uses uimafit so you'll have to translate it in UIMA terms but it might be a starting point.
