We incorporated into the evaluation tests the idea of negative points per incorrect answer, which is described. Knowledge of basics, rules and semantics of the language, and also training of(More)
Models of behavior mining from logs in adaptive systems are one from many methods how to obtain useful information for personalized navigation. Target of this paper is to describe modified results of full scan algorithm used to creation recommended links to concepts. For creation recommended links is used technique of traversal patterns. Established weights(More)
