摘要:

为了使面向任务的对话系统最大限度地发挥作用,它必须能够以一种方式来处理对话,该方式是(1)对于新的任务域,可以用少量的训练样本来概括,以及(2)对于各种风格、模态或域的用户输入是鲁棒的。为了实现这些目标,我们引入了RADDLE基准测试,这是一个用于评估不同领域模型性能的语料库和工具的集合。通过包含具有有限训练数据的任务,RADDLE旨在支持和鼓励具有较强泛化能力的模型。RADDLE还包括一个诊断清单,便于在语言变化、语音错误、不可见实体和域外话语等方面进行详细的鲁棒性分析。我们评估了最近基于预训练和微调的最先进的系统,发现在异构对话语料库上进行接地预训练比每个域训练单独的模型表现更好。总体而言,现有的模型在鲁棒性评价方面不太令人满意,这表明未来有改进的机会。

英文摘要:

For task-oriented dialog systems to be maximally useful, it must be able to process conversations in a way that is (1) generalizable with a small number of training examples for new task domains, and (2) robust to user input in various styles, modalities or domains. In pursuit of these goals, we introduce the RADDLE benchmark, a collection of corpora and tools for evaluating the performance of models across a diverse set of domains. By including tasks with limited training data, RADDLE is designed to favor and encourage models with a strong generalization ability. RADDLE also includes a diagnostic checklist that facilitates detailed robustness analysis in aspects such as language variations, speech errors, unseen entities, and out-of-domain utterances. We evaluate recent state-of-the-art systems based on pre-training and fine-tuning, and find that grounded pre-training on heterogeneous dialog corpora performs better than training a separate model per domain. Overall, existing models are less than satisfactory in robustness evaluation, which suggests opportunities for future improvement.
