Tagging is a metadata creation approach provided by blogs, social bookmarking tools and various web 2.0 applications. Tagging-based systems enable users to categorise content by means of freely chosen keywords, tags.
A tag cloud depicts the content tags of a website. Usually, more frequently used tags are displayed in a larger font, and the display order is alphabetical.
