In this paper, we propose Tutoring bot, a generative chatbot trained on a large scale of tutor-student conversations for English-language learning. To mimic a human tutor's behavior in language education, the tutor bot leverages diverse educational instructions and grounds to each instruction as additional input context for the tutor response generation. As a single instruction generally involves multiple dialogue turns to give the student sufficient speaking practice, the tutor bot is required to monitor and capture when the current instruction should be kept or switched to the next instruction. For that, the tutor bot is learned to not only generate responses but also infer its teaching action and progress on the current conversation simultaneously by a multi-task learning scheme. Our Tutoring bot is deployed under a non-commercial use license at https://tutoringai.com.
翻译:在本文中,我们提议“Tutoring bot ”, 这是一种为英语学习而接受大量教师-学生对话培训的基因性聊天机。为了模仿人类教师在语言教育中的行为,教士机器人将各种教育指示和理由作为每个教学的附加投入内容,作为教师响应生成过程的补充内容。由于一项单一教学通常涉及多次对话,以使学生有足够的发言练习,因此教官机器人在目前的教学应当保留或转换到下一个教学时必须进行监测和捕捉。 为此,教官机器人学会不仅产生反应,而且还通过一个多塔斯克学习计划来推断其教学行动和当前对话的进展。我们的Tutoring bot是在https://tutorringai.com上根据非商业用途许可证部署的。</s>
