Principles, functions, and potential applications of Artificial Intelligence (AI)-based English learning chatbots. (English)

This paper discusses the key technologies and limitations of Al-based chatbots, as well as their types and functions, and their contributions to English language learning. Two specific research questions were posed: first, what are the background and key technologies of Al-based language learning, and what are the technological limitations? Second, what are the conversation processing technologies and types of Al-based chatbots, their roles in English language learning, and pedagogical challenges? Based on the discussion, the main conclusions are as follows: first, the core principles of AI chatbots are human-robot interaction (HRI) technology and natural language processing (NLP) technology, which are evolving into various interactive and game-like models, tailored to the diversity and individuality of learners. Second, natural language processing technology has overcome initial linguistic, technical, and practical challenges and is increasingly being utilized for English language learning through the emergence o£ ChatGPT. Third, AI personal assistant tools can become effective lifestyle English learning tools as natural language processing technology continues to advance. Fourth, Al-based English learning chatbots are effective in pattern matching, conversation database, knowledge base, and language generation models, in that order. Finally, the role and pedagogical challenges of AI chatbots as English language learning tools are discussed. [ABSTRACT FROM AUTHOR]
