Well, in a simple scenario, say NER, we just want to compare the entity 
mentions found by different components (either different analysis 
components, or e.g. a gold standard). Features of the annotation types 
should also be considered during comparison. I thought that such a 
comparator would make new annotations to the CAS for TP/FP/... so that 
from such annotations overall scores (R/P/F) can be calculated.
