    62. 69. Low Cost <ul><li>Low/No Cost alternative to a traditional taxonomy for cataloging Web-based resources. </li></ul><ul><li>Massive rate of publication online between mediums such as blogs, wikis, etc. make a controlled vocabulary impossible. </li></ul><ul><li>Library of Congress collection consists of 130 million items. </li></ul><ul><li>The blogosphere alone produces more than 1.3 million items in the form of new blog posts every day. </li></ul><ul><li>Flickr has a million photos uploaded every day. </li></ul>

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