报告简介:

Traditionally, in management information systems (or collaborative learning systems in particular), user (or learner) group’s detection algorithms primarily focus on the network structure, while clustering algorithms mostly consider only individual user’s attributes. Recent researches reveal that an algorithm upon separated two sources of information may fail to account for important structure in the data. However, combing individual user’s attributes and network topology for user group’s analytics is challenging, partially due to the needs to integrate two very different modalities of information. This direction has drawn intensive researches recently towards social network analytics, but researchers seem to do little work to address the issues and innovate methods and theory to leverage social learning analytics in collaborative work environment or learning systems.

The goal of this talk is to introduce the concepts of users’ (or learners’) interrelated data models, algorithm analyses and implementations for social learning analytics with the integrated clustering attributed graphs. Ultimately, given the application domain in smart and collaborative learning systems, our own learning environment, and the learning environment and cases in other universities will be considered while the dataset and algorithm models are analyzed via the proposed approaches. The approaches can be extended to the application domains where intensive user’s interactions and collaborative knowledge sharing are concerned to leverage better collaboration and workflow management.
