TUTORING: Instruction-Grounded Conversational Agent for Language Learners

In this paper, we propose Tutoring bot, a generative chatbot trained on large scale of tutor-student conversations for English-language learning. To mimic human tutor's behavior in language education, the tutor bot leverages diverse educational instructions and grounds to each instruction as additional input context response generation. As single generally involves multiple dialogue turns give student sufficient speaking practice, is required monitor capture when current should be kept or switched next instruction. For that, learned not only generate responses but also infer its teaching action progress conversation simultaneously by multi-task learning scheme.
