I recognized that there are no False Positive annotations in the evaluation when the type has no annotation in the gold cas, even when I specified a white list of types for evaluation.
Gold standard Document:
<PER>Peter</PER> develops software.
Corresponding document under test:
Peter develops <ORG>software</ORG>.
produces a False Negative for the person annotation, but no False Positive annotation for the organization annotation.
Allow to specify a pattern that filters all types of the typesystem that should be used for evaluation (including creation of false positive annotations).
