CUMULATE is a central user modeling server "designed to provide user modeling functionality to a student-adaptive educational system. It collects evidence (events) about student learning from multiple servers that interact with the student. It stores students' activities and infers their learning characteristics, which are the basis for an individual adaptation to them. ... External and internal inference agents process the flow of events and update the values in the inference model of the server. Each inference agent is responsible for maintaining a specific property in the inference model, such as the current motivation level of the student or the student's current level of knowledge for each course topic..."
