Extensive knowledge bases of entailment rules between predicates are crucial for applied se- mantic inference. In this paper we propose an algorithm that utilizes transitivity constraints to learn a globally-optimal set of entailment rules for typed predicates. We model the task as a graph learning problem and suggest meth- ods that scale the algorithm to larger graphs. We apply the algorithm over a large data set of extracted predicate instances, from which a resource of typed entailment rules has been re- cently released (Schoenmackers et al., 2010). Our results show that using global transitiv- ity information substantially improves perfor- mance over this resource and several base- lines, and that our scaling methods allow us to increase the scope of global learning of entailment-rule ...
