摘要:

在过去的几年里,开放域人机对话已经引起了越来越多的关注。然而,目前还没有一个标准的开放域对话系统的自动评估指标,研究人员通常诉诸于人类的模型评估,这是时间和劳动密集型的注释。在本文中,我们提出了橡胶,一个参考的度量和未参考的度量混合评估例程,它评估的答复,同时考虑到地面实况答复和查询(以前的用户发出的话语)。我们的指标是可学习的,但它的训练不需要人类满意度的标签。因此,RUBER是灵活的,可扩展到不同的数据集和语言。检索和生成对话系统的实验表明,橡胶具有较高的相关性与人类的注释。

英文摘要:

Open-domain human-computer conversation has been attracting increasing attention over the past few years. However, there does not exist a standard automatic evaluation metric for open-domain dialog systems; researchers usually resort to human annotation for model evaluation, which is time- and labor-intensive. In this paper, we propose RUBER, a Referenced metric and Unreferenced metric Blended Evaluation Routine, which evaluates a reply by taking into consideration both a groundtruth reply and a query (previous user-issued utterance). Our metric is learnable, but its training does not require labels of human satisfaction. Hence, RUBER is flexible and extensible to different datasets and languages. Experiments on both retrieval and generative dialog systems show that RUBER has a high correlation with human annotation.
