Learning Objects (LO) have been used for designing e-learning paradigms. Granularity of learning objects is related with the concept of reusability. The reused learning objects are henceforth used for effective personalization. Personalization based on the learner's intuitiveness is preferred using preference based and correlation based algorithms. Based on the user preference and learning style with domain ontology, the effective personalization can be attained. The performance measures and evaluation aids in deciding the learner's effective personalized experience of the system. © 2005 - 2012 JATIT & LLS.
