Subject Re: Ctakes relation extraction
Date Mon, 20 Feb 2017 14:47:56 GMT
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
