Hello, this PR is for the Greek resources that were developed for my thesis at the University of Athens.
I used the WikiWarsEL corpus for the training process and TestWarsEL for the evaluation process.

Evaluation results:

	F-Score	Precision	Recall
Strict Match	85.87	83.37	88.53
Relaxed Match	94.33	91.58	97.25

	Value	Type
Attribute F1	82.31	90.32

Please don't hesitate to contact me for more information.

Best regards.
Manolis.
