title = "Experimental results on user knowledge assessment with an evidential reasoning methodology",
abstract = "User modeling is a crucial element of intelligent interfaces. This paper presents some preliminary results on a method for the assessment of user knowledge. Knowledge of an individual is modeled as a subset of a global set of knowledge units (KU). The KUs are interrelated among each other through implication relations, indicating that certain KUs are prerequisite to others. The structure of implications is induced algorithmically through an induction procedure utilizing empirical data on the knowledge state of a number of subjects. It is thereafter used in a knowledge assessment process based on the Dempster-Shafer evidential reasoning methodology. The preliminary results demonstrate that our approach can successfully assess knowledge by randomly sampling KUs in a knowledge state and infer which KUs are known and unknown.",
