Rule-Based Chatbot Integration into Software Engineering Course

A Chatbot refers to software that can perform services based on commands or answers given by a user during an online conversation. The Chatbots are applied in different areas ranging from pure entertainment solutions to learning support systems. In this article, we investigate Chatbot systems as a way to support learners during educational video sessions. We propose a rule-based Chatbot system that uses speech recognition and synthesized answers for increased immersiveness and for supporting the learners with different sensual perceptions. We introduce the design methodology we followed while creating a Chatbot system, explain the Chatbot behavior from learner and teacher perspectives and describe the system structure. The system was validated using the System Usability Scales (SUS) methodology. It shows that the current implementation has an average usability score; therefore, it needs improvement. On the other hand, the survey shows a positive learners attitude towards the proposed system.
