  5. Alternative Outline How? Why? What? http://zonetag.research.yahoo.com

  6. Information Overload? • Flickr “geotagged” http://zonetag.research.yahoo.com

  7. What can we derive? • Given all photos from a geographic region, • find a “representative” summary set • generate a meaningful visualization • Dataset: (photo_id, user_id, latitude, longitude) (photo_id, tag) http://zonetag.research.yahoo.com

  8. Issues to Tackle • Noisy data • Photographer biases • In locations • In Tags • Wrong data Whatever, color, city, spectrum, santa barbara, california, usa, Lookatme, Herbert Bayer Chromatic Gate http://zonetag.research.yahoo.com

  9. Intuition • More “activity” in a certain location indicates importance of that location • Tag that are unique to a certain location can suggest importance of that location http://zonetag.research.yahoo.com

  10. (Very) Simple Example http://zonetag.research.yahoo.com

  11. Golden Gate Bridge TransAmerica AT&T Baseball Park Golden Gate Twin Peaks Golden Gate Ocean Beach Bay Bridge Chinatown Summary of San Francisco http://zonetag.research.yahoo.com

  14. Outline • Wisdom of the tags • mining information from geo-tagged photos • ZoneTag • your photos in context • Why we tag • a user study of tagging http://zonetag.research.yahoo.com

  15. Outline How? Why? What? http://zonetag.research.yahoo.com

  16. Another Look at the Tag Map http://zonetag.research.yahoo.com

  17. ZoneTag(?) How would we: Create/store? Find? Share? Discover? “Everything in the world exists to end up in a photograph”-- Susan Sontag http://zonetag.research.yahoo.com

  18. Why Cameraphones? • Programmable • Context-aware • Network-connected • Quality… it’s getting there • Numbers, numbers… • 500,000,000 (Source: Future Image Inc.) http://zonetag.research.yahoo.com

  19. Current Mobile Experience • Difficult to share (or even save!) • Hard to find • No context • No semantic information http://zonetag.research.yahoo.com

  20. ZoneTag Experience • 2-click upload (same key!) • Photo uploaded with location and time metadata http://zonetag.research.yahoo.com

  21. ZoneTag Experience • Tagging made easy • Tag/annotate your photos from the phone http://zonetag.research.yahoo.com

  22. Where do locations come from? • Bluetooth GPS (when available) • User-contributed cell tower mapping http://zonetag.research.yahoo.com

  23. Where do tags come from? • Tags I used in this context (`home’) • Tags my friends used in this context (`Research Meeting’) • Tags other people used in this context (`PARC’, ‘Mor Naaman’, `This talk sucks’) http://zonetag.research.yahoo.com

  24. Where do tags come from? • Stuff around you: • Yahoo! Local • Upcoming.org (`Mor Naaman @ PARC’, `PARC George E. Pake Auditorium’) • Stuff from you (any RSS 2.0 feed): • Calendar (G, Upcoming.org, Kiko,…) • Favorite hangouts http://zonetag.research.yahoo.com

  25. Suggested Tags “When I went to upload, there were already all these exotic tags like "Bill Graham Civic Auditorium" and "Bob dylan live" available...it sure was convenient to just select and go…” http://zonetag.research.yahoo.com

  26. Where do tags go? • Back to the original RSS items • Upcoming.org • Action Tags • Trigger a call to a web service • With parameters • Command line - from your phone Rotate:right Email:dad Group:zonetag Scanr:document http://zonetag.research.yahoo.com

  27. (?) (?) (?) (Bradley Horowitz, elatable.com) I’m Too Lazy (you’re not alone) • Tagging is the means, not the goal • Benefits even if you never tagged a single image http://zonetag.research.yahoo.com

  28. Things We Learned • “Best” feature: 2-click upload • Even users that often tag • For some, last chance to annotate • Mobile tagging - not just experts, not all experts… http://zonetag.research.yahoo.com

  29. Things We Learned • Tagging behavior: • All over the place • More than Shozu • Connected to privacy http://zonetag.research.yahoo.com

  30. Outline • Wisdom of the tags • mining information from geo-tagged photos • ZoneTag • your photos in context • Why we tag • a user study of tagging http://zonetag.research.yahoo.com

  31. Outline How? Why? What? http://zonetag.research.yahoo.com

  32. Why Tag? • What are tags? http://zonetag.research.yahoo.com

  33. Why Tag? Bay Bridge, Fog, [San Francisco, 94105] http://zonetag.research.yahoo.com

  34. Why Tag? RedSox, Fenway, GreenMonster, [Boston, 02215], … http://zonetag.research.yahoo.com

  35. Why Tag? Liz, sunbathing, sunny, sunglasses, concrete, [Palo Alto, 94306], … http://zonetag.research.yahoo.com

  36. Tag Affordances on Flickr • Displayed next to photo • Can be used to search: • Your own photos • Others’ photos • Public photos http://zonetag.research.yahoo.com

  37. Tags on ZoneTag • By default, tags are kept from one photo to next • Tags used in a location will be suggested in that location • To you • To others • Immediate (i.e., during event) • Place name tags added automatically http://zonetag.research.yahoo.com

  38. User Study • 13 ZoneTag users (23-45, 9m, 4f) • All “taggers” (no use to ask non-taggers why they tag) • Structured interviews http://zonetag.research.yahoo.com

  39. Expected… • Organization/retrieval • Creator/synthesizer • “Tagging for community” http://zonetag.research.yahoo.com

  40. Found… • Motivation taxonomy • No “synthesizers” • Inspired by community • Organization/retrieval • Creator/Synthesizer • “Tagging for community” X http://zonetag.research.yahoo.com

  41. Motivation Taxonomy “If I tagged ahead of time I can go back and get all my pictures of [my children]…” “…I then think “well, maybe I should tag this” so I can find it again later” “I’m obsessive-compulsive” http://zonetag.research.yahoo.com

  42. Motivation Taxonomy “I want at least one hook of association in there that can help me reconstruct…” http://zonetag.research.yahoo.com

  43. Motivation Taxonomy “...at night, by the fires all around the market, ... at each word that one man says -- such as 'wolf', 'sister', 'hidden treasure', 'battle', 'scabies', 'lovers' -- the others tell, each one, his tale of wolves, sisters, treasures, scabies, lovers, battles.” -- Italo Calvino, Invisible Cities “I tag photos with what I think might be interesting to other people, stuff I think people will like” “I know that tagging can connect my photos to activities, and get more interest” “I want to look at all [my neighborhood’s] tags. … That’s definitely a reason I’m putting these tags in ” http://zonetag.research.yahoo.com

  44. Motivation Taxonomy “…so that my friends can see what I am up to” I can tell my mom [with the tag] “look, we went to…” “I left reviews of places – like at the airport, when my flight was delayed, I tagged “Aloha Air sucks.” http://zonetag.research.yahoo.com

  45. Breakdown http://zonetag.research.yahoo.com

  46. Suggested Tags • Useful for entry, when they “work” • Critical mass needed • Better filtering • Inspire and give example • Overtagging may be issue “Tag suggestions were huge for me; they really cut down on typing” “I thought: this is how I want it to work all the time!” “This person was in my phone for a month - who is she???” “I try to use as many suggested tags that apply. … I also use it for auto-completion – I type “s” to get San Francisco” http://zonetag.research.yahoo.com

  47. Open Questions • Those who don’t… • Better filtering, tag suggestions • Longer usage trends • Effect of community on usage • … http://zonetag.research.yahoo.com
