NELL data for KGEval and noise perturbation experiments

=========================================

1. beliefs : NELL sports subset
	Column 1: belief_ID
	Column 2: subject
	Column 3: predicate-relation
	Column 4: object


=========================================

2. horn_clause : PRA rules used for inference
	TAB separated paths of predicate-relations.
	Each line contains one horn-clause i.e. one path
	'_' prefix for predicate-relation refers to inverse of subject or object
		for example "Detroit _teamPlaysInCity RedWings"
