Embodiment Construction

[0057] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0058] Aiming at the problems existing in the prior art, the present invention aims at the problems that the current online course platform target object interaction relationship is sparse and the online theme learning community cannot provide accurate learning guidance for target objects, especially inert target objects and cold start target objects. The academic friend relationship data in the social network complements the learning relationship data (classmate relationship, teacher-student relationship) of the target object in the online course platform, and detects the ...

Abstract

The invention discloses a learner potential overlapping community detection method, device, equipment and medium. The method includes: abstracting the social relationship data and learning relationship data of a target object into a learner relationship network; acquiring the target object in the academic social network Academic friend relationship, complementing the learner relationship network; searching the learner relationship network high-order structure triangle motif in the learner relationship network after completion, and constructing the adjacency matrix of the triangle motif; according to The adjacency matrix determines node labels in the learner relationship network; according to the node labels, determines the detection result of the potential overlapping community of the target object. The invention improves the quality and accuracy of target object potential overlapping community detection, and can be widely used in the technical field of data mining.

Description

technical field [0001] The invention relates to the technical field of data mining, in particular to a method, device, equipment and medium for detecting potential overlapping communities of learners. Background technique [0002] For the target audience, the online course platform is an extremely free learning environment. Most of them do not have strict teaching organization forms such as classrooms or classes. A course has thousands or even tens of thousands of target audiences, and the target audiences are distributed There are significant differences in age structure, knowledge level, subject background and even learning purpose. Therefore, "gathering" target objects with similar professional backgrounds, learning interests, knowledge levels, and even geographical proximity (discovery communities) helps to standardize and guide learning behaviors, and provides guidance for target objects, especially those who need accurate personalized learning. Target objects (lazy ta...
