Exploring Social Annotations for E-learning

In social annotation services, there is some semantic relatedness hidden behind the co-occurrences of users, resources and tags. This paper aims to explore the implicit information and semantics with a case study of the dasiae-learningpsila annotation. Users feature, resources distribution and dasiae-learningpsila tag co-occurrence network are investigated. The results are helpful to develop learning community and system, design adaptive learning materials and form domain concepts. Although the paper instantiates the study in the context of e-learning, the methodology is generic.
