Unfortunately, there was a bug in a recent data population that we did
and the semantic types are currently unavailable in the Annotator. We're
working on re-populating the data and it should be available in 3-4
As a workaround, you can call use our web services to look up the
semantic type for the concepts that are returned by the annotator,
removing those that don't match your preferred list. Documentation on
using the term service is available here:
Please let me know if you have any other questions.
