Abstract

In this paper, we introduce a new framework for recognizing textual entailment which depends on extraction of the set of publicly-held beliefs -- known as discourse commitments -- that can be ascribed to the author of a text or a hypothesis. Once a set of commitments have been extracted from a t-h pair, the task of recognizing textual entailment is reduced to the identification of the commitments from a t which support the inference of the h. Promising results were achieved: our system correctly identified more than 80% of examples from the RTE-3 Test Set correctly, without the need for additional sources of training data or other web-based resources.
基于话语承诺的语篇蕴涵识别框架
在本文中,我们引入了一个识别文本蕴涵的新框架,该框架依赖于提取一组公开持有的信念(称为话语承诺),这些信念可以归因于文本的作者或假设。一旦从t-h对中提取了一组承诺,识别文本蕴意的任务就简化为从t中识别支持h推理的承诺。取得了令人鼓舞的结果:我们的系统正确识别了RTE-3测试集中80%以上的例子,而不需要额外的训练数据或其他基于web的资源。
