Abstract

The use of artificial intelligent chatbots in industry and education has significantly increased these years. Most of them are used as customer support or as student tutoring. In both situations, the bot is trained to perform a question/answer task. In contrast, few systems are known to assist user's assessment, and even less so, language assessment. The goal of this master thesis is to design and implement a chatbot capable of assessing the user's level into the CEFR framework while having a natural conversation with him/her. We divided the problematic of building such system into two distinct sub-problems. First, we study the different components of a chatbot and analyse various existing solutions. Second, we explore the fields of automated assessment particularly and short answers assessment. Finally, we implement a solution combining the two different parts of this work. Experimentations help us to point out critical aspects of our work that can be improved in further work.
