Diversity of structures and adaptive methods on an evolutionary hypermedia system

SEM-HP is a model for the development of evolutionary and adaptive hypermedia systems by means of: a development process that consists in iterative and evolutionary phases; a layered architecture that captures each phase in subsystems divided into two levels of abstraction (system and metasystem); and an author tool that implements the model. The paper focuses on the capability of adaptation of the hypermedia systems developed according to the SEM-HP model, in particular, the learning subsystem that is in charge of performing the user adaptation. SEM-HP offers two important contributions: supporting the process of evolution of the development of adaptive hypermedia systems, ensuring easy, flexible and consistent maintenance; and the orientation support is that inherent to the navigational structure itself.
