Tagging: What and Why?

- Searching:

• Social Bookmarking
• Mata data – data about data, give the information about data that user collect and tagging

• Folksonomy – use the collaborative theory to classified the data
• Tag cloud – show user tagging and tag topic will be bigger if user give the attention
• Clod start – there is a few information about this data and user just start tagging this topic so, there are no information behind this topic
• Faceted search – user can apply filter to explore the data such as food and book. The information that use want to find is already save in the server like finding the book in the library.

- Traditional Classified:

• Pre-defined vocabulary – use to find the keywords
• Structure
• Done by author or librarian
• Non trivial task – this task must be considered

Social tagging is show interesting research challenge by using the mix of control, user behavior, information retrieval and interface design. The purpose of tagging is for supporting users’ tasks.
