Building a Large-Scale Repository of Textual Entailment Rules
Milen Kouylekov, Bernardo Magnini · 2006
Entailment rules are rules where the left hand side (LHS) specifies some knowledge which entails the knowledge expressed in the RHS of the rule, with some degree of confidence.Simple entailment rules can be combined in complex entailment chains, which in turn are at the basis of entailment-based reasoning, which has been recently proposed as a pervasive and application independent approach to Natural Language Understanding.We present the first release of a large-scale repository of entailment rules at the lexical level, which have been derived from a number of available resources, including WordNet and a word similarity database.Experiments on the PASCAL-RTE dataset show that this resource plays a crucial role in recognizing textual entailment.
