Abstract: A device may identify a first concept hierarchy of a first multimedia presentation and a second concept hierarchy of a second multimedia presentation. The device may determine a set of concepts associated with the first concept hierarchy and the second concept hierarchy and may determine a plurality of similarity scores associated with the set of concepts. The device may generate a new concept hierarchy based on the plurality of similarity scores, the first concept hierarchy, and the second concept hierarchy by: performing a first process to merge a concept with an additional concept; performing a second process to position a concept sequentially before or after an additional concept; performing a third process to position a concept and a different concept to sequentially follow an additional concept; and performing a fourth process to position a concept to sequentially follow an additional concept and a different concept.

Abstract: According to an example, with respect to knowledge graph based learning content generation, a plurality of concepts may be extracted from a plurality of documents. A word embedding similarity, and pointwise mutual information may be determined between each concept of the plurality of concepts. A concept similarity may be determined between each concept of the plurality of concepts, and a plurality of concept pairs that include similar concepts may be identified. A relationship may be determined between concepts for each concept pair of the plurality of concept pairs, and a determination may be made as to whether a concept of a concept pair is a pre-requisite of another concept of the concept pair to generate a knowledge graph. Based on the knowledge graph, a plurality of attributes and a learning goal for a learner, a concept of the plurality of concepts that matches the learning goal may be determined.
