  2. What Are Tags? “A tag is a keyword or descriptive term associated with an item as means of classification by means of a folksonomy. Tags are usually chosen informally and personally by the author/creator of the item — i.e. not usually as part of some formally defined classification scheme. Tags are typically used in dynamic, flexible, automatically generated internet taxonomies for online resources such as computer files, web pages, digital images, and internet bookmarks.” Wikipedia, 2006 Cameron Marlow - Yahoo!

  5. Why Yahoo? Yahoo, circa 1996 Cameron Marlow - Yahoo! Research

  6. Why Yahoo? Yahoo, circa 2004 Cameron Marlow - Yahoo! Research

  7. Why Yahoo? + Cameron Marlow - Yahoo! Research

  8. Motivation • Introduce tagging for academic audiences • Create a common language for current practitioners • Point to potential and possible directions of further research • Method • Develop a model of tagging • Survey existing systems and features • Develop taxonomy Tagging Model Taxonomy Prelim. Study Future Work Cameron Marlow - Yahoo! Research

  9. Tagging Systems: Simple Model Cameron Marlow - Yahoo! Research

  10. (Automatic resource compilation by analyzing hyperlink structure and associated text, Chakrabarti et al, 1998) Tagging - Simple Model • Keywords • Describing connected resources • Sounds familiar? Cameron Marlow - Yahoo! Research

  11. What About Anchor Text? • Democratization and personalization • Extent and scale • User-inclusive model (not site- or page-based) • Notion of connected/related users • Intent of action (e.g., description vs. navigation or reference) • Richness of context Cameron Marlow - Yahoo! Research

  12. Wait! Where Are We? Taxonomy Prelim Study Tagging Model Future Work Cameron Marlow - Yahoo! Research

  13. Taxonomy • Create a common language • Point out differences and generative factors • Two taxonomies • Systems • Incentives (see paper) Cameron Marlow - Yahoo! Research

  14. Systems Taxonomy • Who • How • What • Where from • … Structure and nature of resulting tags Cameron Marlow - Yahoo! Research

  15. Tagging Rights • Who is allowed to tag a resource? Self-tagging Permission-based Open Cameron Marlow - Yahoo! Research

  16. Tagging Support • Does the system “help” in tagging? Blind Suggested Viewable Cameron Marlow - Yahoo! Research

  17. Tag Aggregation • How tags for individual resources are aggregated Set Bag Cameron Marlow - Yahoo! Research

  18. Object Type • What is the type of resource being tagged? Textual Non-textual Cameron Marlow - Yahoo! Research

  19. Object Source • Where the object media originates from User-contributed System Global Cameron Marlow - Yahoo! Research

  20. Where are we now? Tagging Model Taxonomy Prelim. Study Future Work Cameron Marlow - Yahoo! Research

  21. Case Study: Flickr and Del.icio.us • Flickr • Rights: Permission-based • Support: Blind • Aggregation: Set • Type: Non-textual • Source: User-contributed • Del.icio.us • Rights: Owner • Support: Suggested • Aggregation: Bag • Type: Textual • Source: Global Cameron Marlow - Yahoo! Research

  22. Growth of tags • Number of distinct tags in 10 user collections, over time Total number of distinct tags Index of photo Cameron Marlow - Yahoo! Research

  23. Similar to del.icio.us? Scales are different! Figure from Golder et al, 2005 1000 500 0 Total number of distinct tags 0 2500 5000 Index of bookmark Cameron Marlow - Yahoo! Research

  24. Together Total number of distinct tags Index of photo Cameron Marlow - Yahoo! Research

  25. Case Study: Flickr and Del.icio.us • Flickr • Rights: Permission-based • Support: Blind • Aggregation: Set • Type: Non-textual • Source: User-contributed • Del.icio.us • Rights: Owner • Support: Suggested • Aggregation: Bag • Type: Textual • Source: Global Cameron Marlow - Yahoo! Research

  26. Case Study: Flickr • Nobody tags other people’s content • Why? Not collected In user’s account Not identified As coming from the tagger Not prominent In the interface, as “opinion” Not aggregated Can’t “vote” on tag/item pair Cameron Marlow - Yahoo! Research

  27. Almost done Tagging Model Taxonomy Prelim. Study Future Work Cameron Marlow - Yahoo! Research

  28. Future Research • Search / IR • Comparison of hypertext and tags • Spam detection • Linguistics / NLP • Taxonomy generation • Sociolinguistics • Collaborative Filtering • Identify trends (locally and globally) • Trust metrics • Identify influencers • … Cameron Marlow - Yahoo! Research
