  • Patent number: 10943499
    Abstract: A method for providing learning information is provided. The method includes: with reference to two or more supplementary learning patterns experienced by a learner, determining an personalized frequency index related to at least one learning unit commonly included in the two or more supplementary learning patterns; and determining a learning unit having a personalized frequency index higher than or equal to a pre-configured reference, as a personalized supplementary learning unit to be provided to the learner. Each of the two or more supplementary learning patterns includes two or more learning units having a predetermined correlation, and the predetermined correlation is acquired from a knowledge map, which includes two or more nodes corresponding to the two or more learning units and at least one link which connects the two or more nodes and is assigned the correlation between the two or more learning units.
