Addressing the Challenges of Survey Fatigue for Lifelong User Modelling: Initialising Baseline Models Using Community Psychometric Values
Victoria Macarthur, Owen Conlan · 2012
Addressing the issue of survey fatigue is of vital importance for systems that support lifelong learning. This is because of the increasingly complex methods of measurement needed to initialise cognitive user models. This paper describes a baseline cognitive modelling approach whereby user models can be initialised with psychometric measurements form the target community. A critical analysis of current challenges and solutions to overcoming the cold-start condition are outlined. The current approaches to initialising the user model in Technology Enhanced Learning (TEL) are also described. Evaluation of this baseline modelling approach applied to metacognition indicates this method can suitably describe a learner community and result in positive learning outcomes.
