Table of Contents  Summary  Analysis  Question Time
Summary “Information about information - labeling, cataloging and descriptive information structured in such a way that allows Web pages to be properly searched and processed in particular by computer “ (Metadata, 2002) There are three identified core practices in metadata generation (Brun, 2008, p. 172) These are; Tagging Linking browsing What is Metadata
Summary A tag is a keyword or term associated with or assigned to a piece of information For example: a picture Article Video clip  A tag describes the item and enabling keyword-based classification of information and is usually chosen informally and personally by item author/creator or by its consumer/viewers/community (Red Alkemi, 2011) What is Tagging
A term used together with folksonomy folksonomy - a "bottom-up" organizational category that "emerge[s] when individuals tag or describe information and images and those tags are pooled". Alternative for Taxonomy What is Folksonomy?
Summary Types of Tags Identify what or whom it is about?  Identify what it is  Identify who owns it  Refining Categories Identifying Qualities or Characteristics  Self Reference  Organises information (Ames, M., and Naaman, M. (2007). Why We Tag )
Examples of Tagging Tumbler Blogging
Examples of Tagging Web-based service for collective tagging

Chinese Tagging Examples
Summary Advantage of Tagging Disadvantage of Tagging Improve the efficiency of information organization but decrease the cost. Enrich the description of information Personalize information organization Identify People People are lazy People are hypocritical  People may make some small but fatal mistakes (Montero, Y. & Solana, V. (2006).
Analysis Metadata enables the management of diversified contents on the web.  One form of this is tagging.  Google uses an algorithm to bring up the relevant information, “Google is able to extract useful information from the third key source of user-generated metadata in the present environment” (Bruns, 2008, p.174) Metadata
Analysis Tagging has become very popular because its systems have the potential to improve search, spam detection, reputation systems, and personal organization. All doing this while introducing new modalities of social communication and opportunities for data mining.” (Marlow, 2006).   Tag has brought convenience to people.  Tag clouds and folksonomies automatically help create communities as users with similar interests gravitate toward similar, searchable word tags.  Tagged content increases the amount of usable retrievals by providing more than one place you can look for information on the same topic (Doug Johnson, 2007).  Metadata using tagging
Questions Is it necessary to educate people how to tag in an appropriate way. If it is, how? Can we get reliable information with considering that ideas come from various people? If tagging is considered to be a way to manage knowledge, what role does the user take on? A describer or organizer? If this is the popular trend or emerging way of classifying knowledge (if not the future), should there be a guideline for effective tagging?
