What is Tag Cloud

Modern Web 2.0 technologies facilitate the collaboration and sharing of information among users, thereby enabling cooperative processes of information search. One kind of user participation is collaborative tagging, where individuals assign keywords to resources and objects on the Internet. Through the allocation of keywords, objects are enhanced with user-created metadata which results in the so-called folksonomies. This chapter focuses on the classification of tags based on function and user motivation, examines advantages and disadvantages of folksonomies, and provides a review of current applications using collaborative tagging. Future trends and potential developments are identified as they relate to the implementation of collaborative tagging in corporate settings.
