58. Slide 65: Currency • Instantaneous Results • Changes and/or additions to the taxonomy are added to the whole as quickly as they are made by the individuals.
59. Slide 66: Discovery Potential
60. Slide 67: Insight into User Behavior
61. Slide 68: Community • The social nature of tagging engenders a sense of community. • People have a common goal of cataloging their own information, but also sharing it with others. • Offers a chance to view what people have tagged with a word, also how others categorized a particular resource. • Involves the user and gets them invested in a website or brand.
62. Slide 69: Low Cost • Low/No Cost alternative to a traditional taxonomy for cataloging Web-based resources. • Massive rate of publication online between mediums such as blogs, wikis, etc. make a controlled vocabulary impossible. • Library of Congress collection consists of 130 million items. • The blogosphere alone produces more than 1.3 million items in the form of new blog posts every day. • Flickr has a million photos uploaded every day.

66. Slide 73: Limitations?
67. Slide 74: Lack of Synonym Control
68. Slide 75: Lack of Hierarchy • Folksonomies are flat, there are no parent- child relationships, no sub-categories. • Makes for a less robust classification system than the traditional taxonomy. • This limits the ability to add context to tags.
69. Slide 76: Lack of Precision • Discovery Systems • Folksonomies don’t have any hierarchical relationships, making searches less precise.
70. Slide 77: Lack of Recall • Recall: the ability of a system to return all resources related to a topic. • Because of lack of synonym control, a search of a folksonomy will not effect a complete results list because of the use of similar tags. • A search for cat will usually not retrieve resources which have been tagged with kitten, feline, or tabby.
71. Slide 78: Susceptible to Spam • Because these systems are open, spammers and/or unethical users out to corrupt a system could propagate bad tags.
