A study for the development of an English learning chatbot system based on Artificial Intelligence

Artificial Intelligence has become a big part of our daily lives. The key technology of Artificial Intelligence, machine learning and deep learning, has developed chatbot. Chatbot is a conversational agent system which has recently been programmed to perform a variety of tasks such as shopping, making reservations, giving consultation, and other noteworthy tasks which require interaction with human users. Global ICT companies have increased efforts to develop advanced chatbot systems which provide a variety of chatbot services to mobile users through their Messenger platform. Although the incorporation of chatbot systems into our daily lives has seen rapid progression, the development of English learning chatbot systems has not seen the same amount of advancement. The purpose of this study is to provide theoretical background for the development of an English learning chatbot system based on Artificial Intelligence. First of all, in this study, an analysis of the core technology of Artificial Intelligence such as machine learning, deep learning and natural language processes was provided. Then, the recent developmental status of chatbot based on the messenger interface was examined. Finally, a developmental plan for the design of a chatbot for English learning was provided. As a developmental plan for designing an English learning chatbot, object and non-object oriented chatbot systems were suggested. For the object oriented chatbot, application plans of a limited theme and database were introduced. For the design of the non-object oriented chatbot, application plans for a database, a diamond tree diagram, function keys, and emoticons were proposed.
