Designing Tag Navigation

  1. 1. Desiging Tag Navigation November 2007

  3. 3. Metadata
  4. 4. The Navigation Layer “ [Filters] help people move from the world they know (“hits”) to the world they don’t (“niches”)… ” “ Soon everything will make it to the market and the real opportunity will be sorting it all out. ”
  5. 5. 1. Owner-Created Metadata Pros • Consistent terms • Comprehensive Cons • Time intensive to create • Maintenance • Inflexible, rigid Example: Controlled Vocabulary
  6. 6. 2. Technically Generated Metadata Cons Pros • Can be inaccurate • Scales up • Performance intensive • Quick, timely • High cost to enter • Inexpensive to run Examples: Entity Extraction
  7. 7. 3. User-Generated Metadata Pros • Low maintenance • Self-generating organization • Low costs to get started • OK for an answer Cons • Lacks comprehensiveness • Requires incubation time • Navigating other's tags difficult Example: Tagging
  8. 8. Tagging ≠ Tag Cloud
  9. 9. Tagging Process Why do people tag? • Re-find something of value • Share a resource or object with others Three key stages of tagging 1. Creating tags 2. Using and managing your own tags 3. Using other people’s tags

  23. 23. Conclusions Tagging offers an alternative to top-down classification Tags are still just another type of metadata Tagging doesn’t necessarily mean using a tag cloud Understand the broader tagging context People must be able to navigate tags effectively In designing a tagging system, three stages are critical: 1. Creating tags 2. Navigating your own tags 3. Navigating the tags of others
