The script oie_evaluation.py includes several functions which can be used for OIE evaluation. It cannot be executed without creating a corresponding main file. I have used these functions in my own OIE system, which focuses on combining semantic hyperedges with annotations from the LSOIE dataset for a supervised rule learning process. This system will be available as part of the newpotato framework (https://github.com/adaamko/newpotato) in near future.

I have added a check to make sure that the correct number of variables is returned in apply_variables() in graphbrain/patterns
/variables.pyx.
