@Tanja, I was wondering if adding roles would increase significantly the training time for CRFEntityExtractor ? The training for this extractor used to take no more than 2-3 mins and now takes 1h45, although I just added 2 entities with 2 roles ( the roles are the same for both entities), and around 100 sentences with these entities and roles (the extraction is working well, apart from this training time problem…) I haven’t seen anyone complaining about this problem so I’m quite curious.
