Subject RE: Ctakes relation extraction
Date Fri, 24 Feb 2017 09:07:25 GMT
Hi Dmitriy.

Thank you for your reply.

I am not sure how can I extract location_of and degree_of.
AggregateTemplateFiller doesn't return anything in CVD as well as 
TemporalAggregatePipeline.
There is BinaryTextRelation class that as I understand should fill in 
relations but no data is displayed.

I was trying to execute RelationExtractorPipelineSingleCas but it doesn't 
print anything related to relations.

Could you please help me with extraction of relations from the med text ?

As I am a new to ctakes and uima could you please provide step to step 
instructions and exact classes to use.


Thanks in advance,
Oleg.

Hi Oleg,

The relation extraction AE currently only handles location_of and degree_of 
relations as described here:

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3994852/

The dependencies are handled by the dependency parser (i.e. a separate 
module).

So you’ll need to run both and collect all annotated relations from the the 
CAS.

Hope this helps.

Dima
