Models and tools to enable computational reuse of learners heterogeneous profiles

In this paper, we present our work about reuse of learners profiles carried out within the PERLEA project. We address the issue of reuse of heterogeneous profiles by actors (human or software) different from their creators. These profiles can be pencil and paper or coming from software, they can be existing or to be created, and we don’t know they structure. Our approach consists in rewriting a posteriori the profiles in a common formalism thanks to semi-automatic processes. After a presentation of the model of learners profiles management process that we propose, we detail the profiles harmonization step, the profile modeling language that we established to allow this harmonization, and we show the tools we implemented to operationalize this process
