  • 1. Metadata &amp; Tagging<br />MDIA5003 – Assignment 4<br />By Marylove, Sky &amp; Vivian<br />
  • 2. Table of Contents<br /> Summary<br /> Analysis<br /> Question Time<br />
  • 3. Summary<br />“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)<br />There are three identified core practices in metadata generation (Brun, 2008, p. 172)<br />These are;<br />Tagging<br />Linking<br />browsing<br />What is Metadata<br />
  • 4. Summary<br />A tag is a keyword or term associated with or assigned to a piece of information For example:<br />a picture<br />Article<br />Video clip <br />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)<br />What is Tagging<br />
  • 5. A term used together with folksonomy<br />folksonomy - a &quot;bottom-up&quot; organizational category that &quot;emerge[s] when individuals tag or describe information and images and those tags are pooled&quot;.<br />Alternative for Taxonomy<br />What is Folksonomy?<br />
  • 6. Summary<br />Types of Tags<br />Identify what or whom it is about? <br />Identify what it is <br />Identify who owns it <br />Refining Categories<br />Identifying Qualities or Characteristics <br />Self Reference <br />Organises information<br />(Ames, M., and Naaman, M. (2007). Why We Tag )<br />
  • 7. Examples of Tagging<br />Tumbler<br />Blogging<br />
  • 8. Examples of Tagging<br />Web-based service for collective tagging<br />
  • 9. Examples using <br />a photo sharing system allowing users to store and tag their personal photos, as well as maintain a network of contacts and tag others photos.<br />
  • 10. Examples using <br />a video sharing system allowing users to upload video content and describe it with tags.<br />
  • 11. Chinese Tagging Examples<br />
  • 12. Summary<br />Advantage of Tagging<br />Disadvantage of Tagging<br />Improve the efficiency of information organization but decrease the cost.<br />Enrich the description of information<br />Personalize information organization<br />Identify People<br />People are lazy<br />People are hypocritical <br />People may make some small but fatal mistakes<br />(Montero, Y. &amp; Solana, V. (2006). <br />
  • 13. Analysis<br />Metadata enables the management of diversified contents on the web. <br />One form of this is tagging. <br />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)<br />Metadata<br />
  • 14. Analysis<br />Tagging has become very popular because its<br />systems have the potential to improve search, spam detection, reputation systems, and personal organization.<br />All doing this while introducing new modalities of social communication and opportunities for data mining.” (Marlow, 2006). <br /> Tag has brought convenience to people. <br />Tag clouds and folksonomies automatically help create communities as users with similar interests gravitate toward similar, searchable word tags. <br />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). <br />Metadata using tagging<br />
  • 15. Questions<br />Is it necessary to educate people how to tag in an appropriate way. If it is, how?<br />Can we get reliable information with considering that ideas come from various people?<br />If tagging is considered to be a way to manage knowledge, what role does the user take on? A describer or organizer?<br />If this is the popular trend or emerging way of classifying knowledge (if not the future), should there be a guideline for effective tagging?<br />
