Shikib Mehri author Maxine Eskenazi author 2020-jul text Association for Computational Linguistics 1st virtual meeting conference publication It is important to define meaningful and interpretable automatic evaluation metrics for open-domain dialog research. Standard language generation metrics have been shown to be ineffective for dialog. This paper introduces the FED metric (fine-grained evaluation of dialog), an automatic evaluation metric which uses DialoGPT, without any fine-tuning or supervision. It also introduces the FED dataset which is constructed by annotating a set of human-system and human-human conversations with eighteen fine-grained dialog qualities. The FED metric (1) does not rely on a ground-truth response, (2) does not require training data and (3) measures fine-grained dialog qualities at both the turn and whole dialog levels. FED attains moderate to strong correlation with human judgement at both levels. mehri-eskenazi-2020-unsupervised https://www.aclweb.org/anthology/2020.sigdial-1.28 2020-jul 225 235
