摘要:

我们提出了一个诊断自然语言推理(NLI)的假设只有基线。特别是当NLI数据集假设推断纯粹基于上下文和假设之间的关系发生时,因此在忽略所提供的上下文的同时评估蕴涵关系是退化的解决方案。然而,通过对10个不同的NLI数据集的实验,我们发现这种方法,我们称之为仅假设模型,能够在许多NLI数据集上显着优于大多数类基线。我们的分析表明,统计不规则性可能允许模型在某些数据集中执行NLI,超出了在没有访问上下文的情况下应该实现的范围。

英文摘要:

We propose a hypothesis only baseline for diagnosing Natural Language Inference (NLI). Especially when an NLI dataset assumes inference is occurring based purely on the relationship between a context and a hypothesis, it follows that assessing entailment relations while ignoring the provided context is a degenerate solution. Yet, through experiments on ten distinct NLI datasets, we find that this approach, which we refer to as a hypothesis-only model, is able to significantly outperform a majority class baseline across a number of NLI datasets. Our analysis suggests that statistical irregularities may allow a model to perform NLI in some datasets beyond what should be achievable without access to the context.
