摘要:

现有的开放域对话响应生成系统的自动评估指标与人类评估的相关性很差。我们专注于通过响应选择来评估响应生成系统。为了通过响应选择正确地评估系统,我们提出了一种方法来构建响应选择测试集与精心挑选的假候选人。具体来说,我们建议构建测试集过滤掉某些类型的错误候选人:(i)那些无关的地面真相的反应和(ii)那些可接受的适当的反应。通过实验,我们表明,通过响应选择与我们的方法开发的测试集评估系统与人类的评价更强的相关性,与广泛使用的自动评价指标,如BLEU相比。

英文摘要:

Existing automatic evaluation metrics for open-domain dialogue response generation systems correlate poorly with human evaluation. We focus on evaluating response generation systems via response selection. To evaluate systems properly via response selection, we propose the method to construct response selection test sets with well-chosen false candidates. Specifically, we propose to construct test sets filtering out some types of false candidates: (i) those unrelated to the ground-truth response and (ii) those acceptable as appropriate responses. Through experiments, we demonstrate that evaluating systems via response selection with the test sets developed by our method correlates more strongly with human evaluation, compared with widely used automatic evaluation metrics such as BLEU.
