Subject RE: Difference between Refsem Class and TextSem class
Date Mon, 05 May 2014 15:14:00 GMT
org.apache.ctakes.typesystem.type.refsem.DiseaseDisorder  annotations are created by the TemplateFillerAnnotator
within ctakes-template-filler. Running AggregateTemplateFiller engine, which is under ctakes-template-filler,
will generate refsem annotations.

The concept behind having separate textsem and refsem annotations is if you have two textsem
annotations, they might refer to a single real-world object.  The goal is to (someday) have
a single refsem annotation per single real-world object, using coreference resolution to determine
which textsem annotations refer to the same thing, and having something to merge and resolve
conflicts between attributes of the coreferenced textsem annotations. That piece (merging
and dealing with conflicts of attributes) doesn’t exist yet.

So for now, the distinction between the refsem and textsem annotation is that refsem annotations
use the output of the relation extraction piece to set the bodyLocation and severity attributes.
