Classification of Utterances Based on Multiple BLEU Scores for Translation-Game-Type CALL Systems

2018 · IEICE Transactions on Information and Systems

This paper proposes a classification method of second-language-learner utterances for interactive computer-assisted language learning systems. This classification method uses three types of bilingual evaluation understudy (BLEU) scores as features for a classifier. The three BLEU …

Contrastive Response Pairs for Automatic Evaluation of Non-task-oriented Neural Conversational Models

2021

Responses generated by neural conversational models (NCMs) for non-task-oriented systems are difficult to evaluate. We propose contrastive response pairs (CRPs) for automatically evaluating responses from non-task-oriented NCMs. We conducted an error analysis on responses generated …
