While a significant amount of research has been devoted to textual entailment, automated entailment from conversational scripts has re- ceived less attention. To address this limi- tation, this paper investigates the problem of conversation entailment: automated inference of hypotheses from conversation scripts. We examine two levels of semantic representa- tions: a basic representation based on syntac- tic parsing from conversation utterances and an augmented representation taking into con- sideration of conversation structures. For each of these levels, we further explore two ways of capturing long distance relations between lan- guage constituents: implicit modeling based on the length of distance and explicit mod- eling based on actual patterns of relations. Our empirical findings have...
