Experiencing Events through User-Generated Media

  1. 1. Experiencing Events through User-Generated MediaRaphaël Troncy <raphael.troncy@eurecom.fr>André Fialho <andre.fialho@cwi.nl>Lynda Hardman <lynda.hardman@cwi.nl>Carsten Saathoff <saathoff@uni-koblenz.de>
  2. 2. What are Events? Events are observable occurrences grouping People Places Time Experiences documented by Media 08/11/2010 - Experiencing Events through User-Generated Media - COLD 2010, Shanghai, China -2

  4. 4. Goals1. Discover PAST, PRESENT and FUTURE events2. Live, relive and predict experiences through shared media3. Identify meaningful and/or interesting relationships between events/media/people 08/11/2010 - Experiencing Events through User-Generated Media - COLD 2010, Shanghai, China -4
  5. 5. Searching for an event 08/11/2010 - Experiencing Events through User-Generated Media - COLD 2010, Shanghai, China -5
  6. 6. Searching for an event 08/11/2010 - Experiencing Events through User-Generated Media - COLD 2010, Shanghai, China -6
  7. 7. There’s a lot of information out there… 08/11/2010 - Experiencing Events through User-Generated Media - COLD 2010, Shanghai, China -7

  9. 9. Organize the mess Event Media Identify behavioral patterns (requirements) Make an abstraction Link the information Design the application Interface Let it “evolve” Linking Open Data cloud diagram, by Richard Cyganiak and Anja Jentzsch. http://lod-cloud.net/ 08/11/2010 - Experiencing Events through User-Generated Media - COLD 2010, Shanghai, China -9
  10. 10. 1st Collect some opinions… Online Survey (n=28), 2 group discussions (n=35)Past Experiences(Memorable Events) Existing Technologies• Discovery • Opinions Scenarios• Decision making • Interests Requirements• Registering & sharing • Suggestions 1st Design Concept• Meaningful relationships • Benefits/drawbacks 08/11/2010 - Experiencing Events through User-Generated Media - COLD 2010, Shanghai, China - 10
  11. 11. 2nd Look into “real” behaviors… Scenario based study (2 sessions, n=15) Opinions Scenarios Reenact 08/11/2010 - Experiencing Events through User-Generated Media - COLD 2010, Shanghai, China - 11
  12. 12. Behavioral Patterns Discovery  Invitations and recommendations  Rely on traditional media  Social networks (facebook - students)  Previously attended events or venues Decision Making  Who’s Joining?  Where, When, How Much? (constraints)  What? (e.g. type, performer, topic)  Subjective factors (fun, atmosphere) 08/11/2010 - Experiencing Events through User-Generated Media - COLD 2010, Shanghai, China - 12
  13. 13. Behavioral Patterns Registering and Sharing  Communicating their experience  Pictures and short videos (for sharing)  Media directories and social networks Meaningful Relationships  Similar categories, attributes and content  User attendance (similar interests, behaviors)  Repeated events (e.g. annual festivals) 08/11/2010 - Experiencing Events through User-Generated Media - COLD 2010, Shanghai, China - 13

  16. 16. Existing Services Single source with overview (?) Allows opportunistic/serendipitous discovery Limited exploration/browsing features Information overload (cluttered, difficult) Information incompleteness (coverage, decision) 08/11/2010 - Experiencing Events through User-Generated Media - COLD 2010, Shanghai, China - 16

  37. 37. Conclusions Event-based approach for users to explore, annotate and share media User studies in order to:  Find out which data are useful for which task  Understand typical behavioral pattern UX can help semantics, semantics can help UX Outstanding challenges in:  Interlinking and curating the data  Scalability (efficient caching) 08/11/2010 - Experiencing Events through User-Generated Media - COLD 2010, Shanghai, China - 37
