For about 30 years, I have worked at the intersection of the fields of Artificial Intelligence (knowledge engineering) and TEL (Technology Enhanced Learning). Its research activities focus on the fields of learning, lifelong learning and cultural heritage for formal and informal learning and the design of new computing environments to support researchers in History of Science and Technology - Digital Humanities. I am interested in the problems of designing environments of learning and cultural mediation based on investigative approaches or connectivism, using social media in open environments of the MOOC type. From a knowledge engineering informational point of view, the issues are as follows: acquisition and representation of knowledge, learning analytics, semantic web and Linked Data, context sensitivity and adaptation, Learning Analytics, and dynamic generation of dashboards to support all stakeholders
