  2. Are we tagging the image, or the imagination?

  3. Imagescape is an interface which enables users to browse words, photos, and the most of all, viewpoints.

  4. Project Description • In Imagescape, a word is visualized with • the words that are most frequent co-tagged • the photos that are tagged with these words • These materials are placed on a landscape, where their relations are conveyed by the space.

  5. Relations around a photo Operator capture time spectrum freeze at that moment

  6. Relations around a photo (cont.) Spectator Operator view capture time spectrum freeze at that moment

  7. Relations around a photo (cont.) Spectator Operator view imagine capture time spectrum freeze at that moment

  8. Relations around a photo (cont.) Spectator Operator view imagine capture spectrum’ time spectrum freeze at that moment

  9. Relations around a photo (cont.) tags Spectator Operator view imagine capture spectrum’ time spectrum freeze at that moment

  10. Relations around a photo (cont.) tags Spectator Operator view imagine capture spectrum’ time spectrum freeze at that moment

  11. Camera Lucida (Roland Barthes) • Studium • the obvious symbolic meaning of a photograph • Punctum • purely personal and dependent on the individual, that which ‘pierces the viewer’

  12. Luis von Ahn’s Image-labeling Game • Each image is labeled when both players reach agreement on their annotation. • The nature of the game encourages players to think like each other.

  13. Photo Tagging on Flickr.com • Most images are tagged only by their owner. • Tagging is • informal, casual • subjective • about viewpoint • about interpretation

  14. Tag-net • We fetch the metafile of 5 million photos • among 300 million photos on Flickr.com • Tag-net is an undirected graph with • node = tag • edge • count when both tags are tagged on one photo • tags have closer meaning with a larger count • Each photo is represented by a tagcloud.

  15. Spring-Embedded Graph Drawing • Depict the relations between objects with space • Virtual springs with different strength and length is simulated between objects. • A topologically-correct map is generated when objects reach equilibrium.

  16. Example: Organization of emotion-related tags

  17. Demo - Imagescape See the spectrum of a concept using public photos and social tagging Love

  18. Discussion

  19. How can we visualize the dynamics of photos and tags?

  20. How can we visualize subjectivity?

  21. How can we visualize a person? • Tag-net as a whole can be view as a mainstream point of view. • However, sometimes, what defines one’s personality is those which conflict to mainstream point of view.
