USR:一种无监督无参考的对话生成评价指标

USR: An Unsupervised and Reference Free Evaluation Metric for Dialog Generation

摘要:

由于缺乏有意义的对话自动评价指标,阻碍了开放域对话的研究。标准的语言生成度量已经被证明对于评估对话模型是无效的。为此,本文提出了USR,一个无监督和无参考的对话评价指标。USR是一个无参考的指标,它训练无监督模型来测量对话的几个理想质量。USR被证明与人类对Topical-Chat(回合级别:0.42,系统级别:1.0)和PersonaChat(回合级别:0.48和系统级别:1.0)的判断密切相关。USR还为对话框的几个理想属性提供了可解释的措施。

英文摘要:

The lack of meaningful automatic evaluation metrics for dialog has impeded open-domain dialog research. Standard language generation metrics have been shown to be ineffective for evaluating dialog models. To this end, this paper presents USR, an UnSupervised and Reference-free evaluation metric for dialog. USR is a reference-free metric that trains unsupervised models to measure several desirable qualities of dialog. USR is shown to strongly correlate with human judgment on both Topical-Chat (turn-level: 0.42, system-level: 1.0) and PersonaChat (turn-level: 0.48 and system-level: 1.0). USR additionally produces interpretable measures for several desirable properties of dialog.
