Would it be possible to run some benchmarks so we know the performance
difference between the two?
The OpenNLP POS Tagger can be customized, currently is possible to
replace the feature generation,
it can probably be optimized for the medical domain, the default feature

Why Apache Mahout?

Yes, the OpenNLP Sentence Detector now supports that in the new 1.5.3

Joern- could you confirm- I think in the latest OpenNLP versions, you can
simply call something like
SentenceModel.serialize(outputstream) now to save the models?
Yes, excatly, this how a model in Open

Instead of it might be better to use and to encode
