A social tagging system for online learning objects

This paper introduces a social tagging platform, where social tagging allows the public to freely tag online resources, denoted as keywords, with any words as well as to share personal opinions on those resources. Social tagging potentially helps users to organize, manage, and retrieve learning resources, which can be regarded as a new kind of metadata. In this paper, we propose a social tagging platform, building on an online depository containing about 4000 learning resources. Specifically, in our system, users are encouraged to collaboratively mark miss-tagging or similar tags, such that the learning objects can be more easily described and more readily searched out. By adopting social tagging tools, the depository can be efficiently and effectively employed by large communities.
