  1. Social Software John C. Tang September 6, 2007

  2. Top 10 student needs • Calendar management (assignments, events) • Computer (power, carrying, features) • Cellphone (texting, usability) • Bathroom controls (temp, sensors) • Transportation (bus schedules, parking)

  3. Top 10 student needs • Communicating with family • Alarm clock waking up • Finding people (teammates, carpool) • Recommendations (dining, activities) • Earphones design

  4. Website updates • Slides from lecture are posted later in the day • Link posted for every assignment • Discussion section topics for some weeks added to schedule (more coming) • Revised office hours for me: Tue, 2:00-3:30

  5. Assignment: Map of Berkeley (Due Sept. 11) • Draw conceptual map of Berkeley that conveys your experience of the area • Introduce me to Berkeley! • Express visually, not with words (like Pictionary) • Create feature list • Show map to one other person not in CS160 • “Here’s a map of Berkeley I drew—tell me what you learn from it” • State relationship to person (e.g., friend, roommate) • Record number of features they recognize • Hand in 2 copies (black & white copy OK)

  6. Grading criteria • How effectively the map communicates feature list to us (the teaching staff) • How effectively the map communicates feature list to user study participant (% features recognized) • Good design balance of how much information to include in the map • Enough to be interesting • Not too much to be cluttered • Keep target user in mind (me!) • Reflect on what you learned from user test

  7. A word about grading… • I’m going to be more explicit about assignments • Please ask if you have any questions • Consider this first assignment as part of a “calibration” process, clarify expectations

  13. Beyond mainstream social software • Email • IM • Web pages • Multi-player games

  14. Work / benefit tradeoff • Cardinal rule for why Computer-Supported Cooperative Work (CSCW) applications fail • Disparity between who does the work and who gets the benefit Jonathan Grudin, “Why CSCW applications fail: Problems in the design and evaluation of organizational interfaces”, CSCW 1988 http://doi.acm.org/10.1145/62266.62273

  15. Social recommending • High data volume • Side effect of purchase records • Regionally customized • Dealing with data pollution (gifts)

  16. Del.icio.us a social bookmarking website … designed to allow you to store and share bookmarks on the web, instead of inside your browser. • Access your bookmarks from anywhere, no matter whether you're at home, at work, in a library, or on a friend's computer. • Share your bookmarks publicly, so your friends, coworkers, and other people can view them for reference, amusement, collaboration, etc. • Find other people on del.icio.us who have interesting bookmarks and add their links to your own collection. Joshua Schachter http://del.icio.us/doc/about

  17. Del.icio.us bookmarking and tagging • Lightweight widgets for • Adding a bookmark • Adding tags to index bookmarks • Interface for seeing • Tags applied to bookmarks • Other bookmarks that others have related to a bookmark • Social feedback—others are copying my bookmarks!

  20. Wikipedia • Peer-contributed content • Community moderated (status) • More diverse, “popular” slant on info • Journal article in Nature that found accuracy of Wikipedia comparable to Encyclopedia Britannica http://www.nature.com/news/2005/051212/full/438900a.html • Can be “dynamic” at times

  21. Temporal artifacts in Wikipedia • History flow visualization of “abortion” http://doi.acm.org/10.1145/985692.985765

  22. Tagging • Indexing for my use • Shared with others • Disambiguating • Translation • Convergence on labels • Seeing others’ tags • Auto-complete

  23. Cambridge, MA and Cambridge, UK

  24. Searching for “azul”

  25. Tag clouds • Usage, recency ~ interesting • Alphabetic for finding

  26. Salience of usage, recency

  27. Social reputations • eBay • Epinions • “genuine” reviews • Evolve over time

  28. Viral adoption • Exposurequick installusagemore exposure • facebook applications

  29. Leveraging physical traffic • ZoneTags • Exploiting location information on cameraphones • Tag photos with location • Suggest tags based on other photos from that location • PhotoSynth • Create 3-D model from photos taken from the same location

  30. ZoneTag http://zonetag.research.yahoo.com/

  31. Photosynth http://labs.live.com/photosynth/default.html
