It depends on the type of annotation.

Some are rule-based. Some are machine-learning based (models).  Some are dictionary dependent.
 And some are based on annotations earlier in the pipeline, and so looking at the part of
speech tags within the tokens, for example, can explain which chunk something appears in,
which can explain why something might not have been annotated as a DiseaseDisorderMention,
for example.  

Are you asking a general question or is there a specific type of annotation you are most interested

Is there a generally accepted procedure for identifying why an annotation
wasnt made?
