  2. SOME DATA ABOUT THE PROJECT • Project call • FP7 4th call - Objective ICT-2009.1.5: Networked Media and 3D Internet (Target outcome ‘c’: Networked search and retrieval) • Type of project: Large-scale Integrated Project • Starting date and duration • December 1st 2009 – 36 months • COORDINATING PARTNER • DISI – University of Trento, Italy • TOTAL PROJECT COSTS • 7.4 Meuro • 816 man/months NEM – Concertation meeting Brussels, Feb. 3-4 2010

  3. THE CONSORTIUM • DISI - Universityof Trento (coordinator) • ISOCO - intelligent Software Components S.A. • Alinari 24Ore SpA • Center forResearch and TechnologyHellas • Yahoo Iberia SL • Agence France PressE • DFKI GmbH • Exalead • L3S - Universitat Hannover • INRIA NEM – Concertation meeting Brussels, Feb. 3-4 2010

  4. GLOCAL OBJECTIVES • Content-basedretrievalsystemsfailed so far toprovidegeneral-purpose, reliablesystems: • semantic gap • content vs. context • New tools are neededtorepresent, organize, index and access media, whichshouldbe: • Intuitive and user-centric(neartohuman way oforganizing data) • Effortless(do notbother the userwithcomplex and time-consumingannotation, tagging, cataloguing, etc) • Scalable and extensible(supporteverincreasingtypes and amountsof media documents) • Distributed (suitedtowidespreadingmedia-driven social networks) NEM – Concertation meeting Brussels, Feb. 3-4 2010

  5. GLOCAL S&T ISSUES • GLOCAL envisages a solution to such problems by exploiting three major assets: • The use of events as a primary mean to contextualize data • The interaction of peersat local and global level to build a social intelligence as the way to automate media organization • The construction of new search paradigmsbased on the above elements NEM – Concertation meeting Brussels, Feb. 3-4 2010

  6. THE GLOCAL MODEL • Events are entities with attributes and relational attributes (links) to other entities (e.g., events, • locations, people, media) • Related events (event network): • Sub-event relationship (granularity) • Cause-effect relationship (causality) • Temporal relationship (continuity) • … Linked locations Linked persons TIME SPACE TYPE EVENT (UID) PERSON EVENT Linked events MEDIA Linkedmedia OTHER • Media populateevents: • Eventscontextualize media (experientialdimension) • Many-to-manyrelationship (viewpoints): • One media linkedtomanyevents • Oneeventlinkedtomany media ATTRIB. NEM – Concertation meeting Brussels, Feb. 3-4 2010

  7. GLOCAL SEARCH Query: a set of metadata from the event model • Simple or composite (QbyText, QbyExample, QbyMetadata, ..., as well as their combination) • No need to specify all parameters (metadata) • Takes into account uncertainty (e.g., temporal and geographic range) QUERY Example • Refinement and navigationmechanisms • Queryansweringproduces a rankedlistofpointersto the event net • Refinementthroughhyperspacenavigation (graphics, interfaces) Event: text description “Soccer match Milan” What Time: temporalrange May 15, 2008 When Milano, Italy Space: geo location Where Milan, Beckham Who Entities: actors, objects Photoof 1st goal Sample media Which NEM – Concertation meeting Brussels, Feb. 3-4 2010

  8. EXAMPLE: A SPORTS EVENT Original query: “Soccer match Milan” Event: Soccer match Milan, Milano, 21.3.09 Sub -Event 1 Sub-event Beckham goal Sub-Event 2 NEM – Concertation meeting Brussels, Feb. 3-4 2010

  9. EXAMPLE: FINDING SIMILAR EVENTS Original query: “Soccer match Milan” Event: Soccer match Milan, Milano, 21.3.09 Matcheswithotherteams, sameleague Other SIMILAR events NEM – Concertation meeting Brussels, Feb. 3-4 2010

  10. EXAMPLE: FINDING PAST EVENTS Original query: “Soccer match Milan” Event: Soccer match Milan, Milano, 21.3.09 Previouseventof the same soccer team Other Milan Soccer matches at different TIME NEM – Concertation meeting Brussels, Feb. 3-4 2010

  11. EXAMPLE: FINDING CO-LOCATED EVENTS Original query: “Soccer match Milan” Event: Soccer match Milan, Milano, 21.3.09 Othereventsaround Milano on 21.3.09 Other events in nearby PLACES NEM – Concertation meeting Brussels, Feb. 3-4 2010

  12. EXAMPLE: AN EVENT NETWORK… Original query: “Soccer match Milan” Matcheswith Beckham in different team Victoria Beckham Event: Soccer match Milan, Milano, 21.3.09 Sub -Event 1 Sub-event Beckham goal Sub-Event 2 Eventswith sameactor Other events with BECKHAM NEM – Concertation meeting Brussels, Feb. 3-4 2010

  13. GLOCAL TECHNOLOGIES • Which are the enabling technologies? • Eventmodelling(media & knowledge) • Eventinstantiation (matchingmodelsto reality: create, evolve and maintainevents) • Eventpopulation(effortlesslyattaching media toevents) • Eventsharing(sharingeventstructures and contents) • Event-basedindexing and search(usingeventstoaccess media) • Event-basedinterfacing (putting the user in the loop) NEM – Concertation meeting Brussels, Feb. 3-4 2010

  14. GLOCAL SCENARIOS kkk Five initial use cases with a lot of UGC content on the web and main events with a rather large set of content (text for metadata, event modeling, photo, video, graphics) NEM – Concertation meeting Brussels, Feb. 3-4 2010
