Designing Tag Navigation

  1. 1. Designing Tag Navigation November 2007
  2. 2. James Kalbach Human Factors Engineer LexisNexis Information Architect Razorfish Germany (2003) Library & Info Science Degree Rutgers University Designing Web Navigation (O‘Reilly, Aug 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
  10. 10. 1. Creating Tags
  11. 11. Encourage Tagging Make it easy to tag
  12. 12. Prompt for Tags Help people find words to use
  13. 13. Tag Form Avoid space-separated tags Newyearseveparty2007 iphone_review to-read Use comma-separated
  14. 14. 2. Navigating Your Own Tags
  15. 15. Provide Different Views Let people navigate in different ways
  16. 16. Navigate Resources Allow people to search their resources
  17. 17. Combine Tags Allow people to combine two tags
  18. 18. 3. Navigating Other People‘s Tags
  19. 19. Enhance Tag Clouds Show context and provide structure
  20. 20. Mix Metadata Expose other types of relevant metadata
  21. 21. Show Tags for Resource Expose tags at the resource-level
  22. 22. Link to Other People Browse the resources of other members
  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 In designing a tagging system, three stages are critical: 1. Creating tags 2. Navigating your own tags 3. Navigating the tags of others People must be able to navigate tags effectively
