Folksonomy / Tagging • Folksonomi merupakan hasil pengategorian oleh pengguna. • Secara demokratis pengguna menerapkan tag sesuai dengan kecocokan mereka terhadap isi materi. • Folksonomi mengatasi kerumitan konsep kategori yang terstruktur formal dan bertingkat yang disebut taksonomi. • Kelemahan folksonomi misalnya tidak luput dari derau (noise), bisa terjadi ada banyak tag/label yang kosakatanya salah, tidak semua user tag/label tersebut cocok
Tagging
Social bookmarking •There are a number of sites for this •By far the most popular is http://del.icio.us •Rather than bookmarking sites locally allows you to have access to your bookmarks from wherever you are. •This is a small example of the “web as desktop” philosophy.
del.icio.us
Fitur Web 2.0 • Search – The ease of finding information through keyword search.
• Links – Ad-hoc guides to other relevant information.
• Authoring – The ability to create constantly updating content over a platform that is shifted from being the creation of a few to being constantly updated, interlinked work. In wikis, the content is iterative in the sense that users undo and redo each other's work. In blogs, content is cumulative in that posts and comments of individuals are accumulated over time.
• Tags – Categorization of content by creating tags: simple, one-word userdetermined descriptions to facilitate searching and avoid rigid, pre-made categories.
• Extensions – Powerful algorithms that leverage the Web as an application platform as well as a document server.
• Signals – The use of RSS technology to rapidly notify users of content changes.
Search • Search the content • Oracle Secure Enterprise Search Oracle Ultra Search • Google Search Appliance
Link • Build links to other content, users, etc. • Tracking/analyzing clicks/usage patterns is key
Authorships • Blogging and allowing users to create their own content • Wikis • Blogspot • Forums
