Folksonomy. An empirical analysis of the complex dynamics of tagging systems, published in 2007,[8] has shown that consensus around stable distributions and shared vocabularies does emerge, even in the absence of a central controlled vocabulary.
For content to be searchable, it should be categorized and grouped. While this was believed to require commonly agreed on sets of content describing tags (much like keywords of a journal article), recent research has found that, in large folksonomies, common structures also emerge on the level of categorizations.[9] Accordingly, it is possible to devise mathematical models of collaborative tagging that allow for translating from personal tag vocabularies (personomies) to the vocabulary shared by most users.[10] Origin[edit] Folksonomy is a type of collaborative tagging system in which the classification of data is done by users.
Social bookmarking. Common features[edit] In a social bookmarking system, users save links to web pages that they want to remember and/or share.
These bookmarks are usually public, and can be saved privately, shared only with specified people or groups, shared only inside certain networks, or another combination of public and private domains. The allowed people can usually view these bookmarks chronologically, by category or tags, or via a search engine.
