Abstract: Systems and methods associated with discussion resource recommendation are disclosed. One example method may be embodied as computer-executable instructions stored on a non-transitory computer-readable medium. The instructions may cause a computer to construct a resource network that links members of asset of online discussion resources. The online discussion resources may be linked based on user participation overlap between members of the set of discussion resources. The instructions may also cause the computer to generate content similarity scores that measure content overlap for pairs of discussion resources. The instructions may also cause the computer to generate network relevancy scores for the pairs of discussion resources based on the resource network. The instructions may also cause the computer to recommend, based on the content similarity scores and the network relevancy scores, a related discussion resource to a user when the user accesses a primary discussion resource.

Abstract: Examples disclosed herein relate to creating a heterogeneous learner group. In one implementation, a processor associates a selected learner with a group of learners based on a value of a factor associated with the group of learners compared to a value of the factor associated with the selected learner. For example, the value associated with the selected learner may be indicative of a strength compared to the value associated with the group of learners. The processor may output information related to a heterogeneous learner group created from the group of learners and the selected learner.
