Information-based item selection with blocking strategy based on a Bayesian network
Tien-Yu Hsieh, Bor‐Chen Kuo · 2010
searching optimal adaptive item sequence in computerised adaptive test systems based on Bayesian network. Information theory such as entropy between dichotomous concepts and test items generalise common intuitions about item comparison for heuristic methodology. However, the executive time and the storage space are still open problems in constructing and storing decision item trees. The blocking strategy is proposed for overcoming those problems. Experimental results show that the blocking strategy could overcome both the executive time and storage space problems.
