摘要:

我们引入了不确定自然语言推理(UNLI),这是自然语言推理(NLI)的一种改进,它远离了分类标签,而是针对主观概率评估的直接预测。我们证明了通过在概率尺度下重新标记SNLI数据集的一部分来为UNLI收集注释的可行性,即使具有相同分类标签的项目在给定前提下人们判断它们为真的可能性也不同。我们描述了一种直接标量回归建模方法,并发现现有的分类标记的NLI数据可以用于预训练。我们最好的模型接近人类的表现,证明模型可能能够比目前NLI任务中采用的分类箱分配更微妙的推断。

英文摘要:

We introduce Uncertain Natural Language Inference (UNLI), a refinement of Natural Language Inference (NLI) that shifts away from categorical labels, targeting instead the direct prediction of subjective probability assessments. We demonstrate the feasibility of collecting annotations for UNLI by relabeling a portion of the SNLI dataset under a probabilistic scale, where items even with the same categorical label differ in how likely people judge them to be true given a premise. We describe a direct scalar regression modeling approach, and find that existing categorically labeled NLI data can be used in pre-training. Our best models approach human performance, demonstrating models may be capable of more subtle inferences than the categorical bin assignment employed in current NLI tasks.
