Uncertainty is when the text indicates some hedging about the concept:
"possible asthma" should have asthma as an IdentifiedAnnotation with the
uncertainty flag set to 1.
This is done by machine learning and it is not easy so it is not perfect.
HistoryOf is for concepts that are explicitly in patient history, often in a
history section.
"history of lymphoma as a child"
lymphoma should have its history flag set to 1.
This is done by machine learning and it is not easy so it is not perfect.
Confidence is a field that I don't believe gets set by any current annotators,
but in theory it is for methods that might use statistical methods that output
a score to set the score there.
The cTAKES dictionary lookup either hits or doesn't, so it doesn't set that
score.
DiscoveryTechnique is a way to flag which entities were annotated by which
annotator, since it's possible to have, e.g., multiple clinical concept
taggers. We use it occasionally internally
to separate gold standard entities from system-discovered entities (in a
machine learning evaluation) but I don't know if any standard pipeline
components set it.

IdentifiedAnnotations [EXTERNAL]
Hi,
Thanks for the replies but I am still not able to understand the significance
of the attributes such as Uncertainty, HistoryOf, Confidence,
DiscoveryTechniques.
Can anyone give some examples or any information which will help me to
understand these concepts in more depth?
Thanks.
