The adaptive learning system is a hotspot in the field of e-learning and intelligent education research. As the below architecture diagram illustrates, the learner model is the core of the adaptive learning system. At the same time, learner models are the foundation of adaptive learning systems that are limited to modeling only a few learner's characteristics, such as learner's knowledge and competencies, but they neglect other parameters that are as important for the adult learner. It should be noted here that domain modeling is an excellent tool for Agile enterprises to carry out a common language and a fundamental structure for analyzing features and epics. The domain model is defined and continuously refactored as enterprise knowledge about the domain improves, and the system functionality evolves.
