Recommendation by Example in Social Annotation Systems
Lecture Notes in Business Information Processing, 2011Recommendation by example is common in contemporary Internet applications providing resources similar to a user-selected example. In this paper this task is considered as a function available within a social annotation system offering new ways to model both users and resources. Using three real-world datasets we motivate several conclusions.

Impact on Performance and Process by a Social Annotation System: A Social Reading Experiment
Lecture Notes in Computer Science, 2009Social annotation systems such as SparTag.us and del.icio.us have been designed to encourage individual reading and marking behaviors that, when shared, accumulate to build collective knowledge spaces. Prior work reported on the experimental design and performance effects observed in a controlled study of SparTag.us.

Uncle-Share: Annotation-Based Access Control for Cooperative and Social Systems
Lecture Notes in Computer Science, 2008Shared workspaces and Web 2.0 platforms provide lots of services for sharing various objects. Most current shared workspaces and Web 2.0 platforms provide role-based, coarse-grained access control policies which undermine the utility of them in some cases.

Hybrid tag recommendation for social annotation systems
Proceedings of the 19th ACM international conference on Information and knowledge management, 2010Social annotation systems allow users to annotate resources with personalized tags and to navigate large and complex information spaces without the need to rely on predefined hierarchies. These systems help users organize and share their own resources, as well as discover new ones annotated by other users.

A scalable, collaborative similarity measure for social annotation systems
Proceedings of the 20th ACM conference on Hypertext and hypermedia, 2009Collaborative annotation tools are in widespread use. The metadata from these systems can be mined to induce semantic relationships among Web objects (sites, pages, tags, concepts, users), which in turn can support improved search, recommendation, and otherWeb applications.

A Study of a Social Annotation Modeling Learning System
Journal of Educational Computing Research, 2011The transition from classroom instruction to e-learning raises pedagogical challenges for university instructors. A controlled integration of e-learning tools into classroom instruction may offer learners tangible benefits and improved effectiveness.

On Kernel Information Propagation for Tag Clustering in Social Annotation Systems
2011In social annotation systems, users label digital resources by using tags which are freely chosen textual descriptors. Tags are used to index, annotate and retrieve resource as an additional metadata of resource. Poor retrieval performance remains a major challenge of most social annotation systems resulting from the severe problems of ambiguity ...

Tag Prediction in Social Annotation Systems Based on CNN and BiLSTM
2018Social annotation systems enable users to annotate large-scale texts with tags which provide a convenient way to discover, share and organize rich information. However, manually annotating massive texts is in general costly in manpower. Therefore, automatic annotation by tag prediction is of great help to improve the efficiency of semantic ...

Resource Recommendation in Social Annotation Systems Based on User Partitioning
2014Social annotation systems have become a staple of the World Wide Web, enabling users to organize their favorite resources with tags. Resource recommenders that exploit these tags to model users and resources have proven to be effective in assisting users navigate complex information spaces, particularly when combined with other approaches.
