Hi Liam, associatedSignSymptom has not been implemented yet.
More details of the relation extraction module are in https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3994852/ I hope this helps you.

It turns out I need to specify the model file: builder.add( AnalysisEngineFactory.createEngineDescription(LocationOfRelationExtractorAnnotator.class, "classifierJarPath", "/org/apache/ctakes/relationextractor/models/location_of/model.jar") ); With that, I manged to extract "bodyLocation" for each Identified Annotation. How about "associatedSignSymptom"? I couldn't find any AnalysisEngine that would outputs this attribute. Thanks.

Based on cTAKES sourcecode, it seems these classes (DiseaseDisroder, Procedure, etc do support such relation through several attributes bodySite, associatedSignSymptom, etc). However, I do not know which cTAKES component or analysis engine that I should use to get these info. I also notice there is cTAKES Relation Extraction component, but I have no idea how to get it running. Does anyone happen to have insight on these topics?
