For the marriage relation, the results not only show that our RTE engine adaptations yielded a much higher recall (with almost no loss in precision) than the original implementation (thanks to an increased number of relevant alignments), but also that pattern selection can in fact benefit from the graph structure: Entailment graphs created using MultiAlignAdapted achieved much better performance than a selection based on pair-wise entailment computation using the same RTE model.
it cannot express that the relation expressed by pattern P3 entails the relation expressed by pattern P1, but not vice versa.
