Artificial intelligence empowered domain modelling bot.

With the increasing adoption of Model-Based Software Engineering (MBSE) to handle the complexity of modern software systems in industry and inclusion of modelling topics in academic curricula, it is no longer a question of whether to use MBSE but how to use it. Acquiring modelling skills to properly build and use models with the help of modelling formalisms are non-trivial learning objectives, which novice modellers struggle to achieve for several reasons. For example, it is difficult for novice modellers to learn to use their abstraction abilities. Also, due to high student-teacher ratios in a typical classroom setting, novice modellers may not receive personalized and timely feedback on their modelling decisions. These issues hinder the novice modellers in improving their modelling skills. Furthermore, a lack of modelling skills among modellers inhibits the adoption and practice of modelling in industry. Therefore, an automated and intelligent solution is required to help modellers and other practitioners in improving their modelling skills. This doctoral research builds an automated and intelligent solution for one modelling formalism - domain models, in an avatar of a domain modelling bot. The bot automatically extracts domain models from problem descriptions written in natural language and generates intelligent recommendations, particularly for teaching modelling literacy to novice modellers. For this domain modelling bot, we leverage the capabilities of various Artificial Intelligence techniques such as Natural Language Processing and Machine Learning.
