  • 3. Metadata
  • 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. 1. Owner-Created Metadata Pros • Consistent terms • Comprehensive Cons • Time intensive to create • Maintenance • Inflexible, rigid Example: Controlled Vocabulary
  • 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. 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

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
