The information about the procedural knowledge in terms of activation builds the user model of AdaptHelp, an adaptive help system for web-based systems. AdaptHelp is based onto established adaptive help systems, which are shortly presented and compared on the used mechanism and techniques.Mon Aug 20 10:25:28 CEST 2018Workshop on the Evaluation of Adaptive Systems, User Modellingis the ACT-value a valid estimate for knowledge?
