Samir,
Actually, the relations are represented in the type system differently.
Please take a look at the BinaryTextRelation type. If you'd like an
example of how to iterate over the relations, take a look at
ctakes-relation-extractor/src/main/java/org/apache/ctakes/relationextractor/pipelines/RelationExtractorConsumer.java.
Once you get a hold of each BinaryTextRelation, you can determine the
relation type by looking at the 'category' attribute.

Hi Dima,
I run RelationExtractorPipelineSingleCas.java and i got
degree_of(severe pain/3, severe/2)
degree_of(pain/3, severe/2)
location_of(pain/3, wrists/6)
but when i run UIMA_CVD--relation-extractor.launch - or
UIMA_CPE--relation-extractor.launch on the hurd coded text "He still is not able
to work because of severe pain involving his wrists." there is no annotation of type:
org.apache.ctakes.typesystem.type.relation.LocationOf
org.apache.ctakes.typesystem.type.relation.DegreeOf
I need to identify the relations by their annotation type so i can iterate on
them
Thanks
Samir

Subject: Re: examples of relation extractor annotations
Samir,
Could you please try to run
ctakes-relation-extractor/src/main/java/org/apache/ctakes/relationextractor/pipelines/RelationExtractorPipelineSingleCas.java
and see if it finds any relations in the hard-coded sample sentence. In that
sentence
"He still is not able to work because of severe pain involving his wrists."
you should see the following relations:
degree_of(severe pain/3, severe/2)
degree_of(pain/3, severe/2)
location_of(pain/3, wrists/6)
which will be printed to the console. The numbers next to each argument are the
UMLS semantic types (e.g. 6 = anatomical site).

Hi,
I tried to get examples of relation extractor annotations using
RelationExtractorAggregate.xml. I tried the RelationExtractorAggregate on many
input medical text but there was no annotation for any kind of relation. I even
tried the bellow text used in RelationExtractorAnnotatorsTest but again no
relation is annotated. Do you have idea or am i missing some thing ?
"He had a slight fracture in the proximal right fibula.",
"He had a slight fracture in the proximal right fibula .",
"PRP VBD DT JJ NN IN DT JJ JJ NN .");
Thanks
Samir
