  • Content-based retrieval systems failed so far to provide general-purpose, reliable systems:semantic gapcontent vs. contextNew tools are needed to represent, organize, index and access media, which should be:Intuitive and user-centric (near to human way of organizing data)Effortless (do not bother the user with complex and time-consuming annotation, tagging, cataloguing, etc) Scalable and extensible (support ever increasing types and amounts of media documents)Distributed (suited to widespreading media-driven social networks)GLOCAL OBJECTIVESNEM Concertation meetingBrussels, Feb. 3-4 2010FP7 248984 - GLOCAL

    NEM Concertation meeting Brussels, Feb. 3-4 2010

  • GLOCAL envisages a solution to such problems by exploiting three major assets:The use of events as a primary mean to contextualize dataThe interaction of peers at local and global level to build a social intelligence as the way to automate media organizationThe construction of new search paradigms based on the above elementsGLOCAL S&T ISSUESNEM Concertation meetingBrussels, Feb. 3-4 2010FP7 248984 - GLOCAL

  • THE GLOCAL MODELEvents 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) Media populate events: Events contextualize media (experiential dimension) Many-to-many relationship (viewpoints):One media linked to many eventsOne event linked to many mediaEVENT(UID)NEM Concertation meetingBrussels, Feb. 3-4 2010FP7 248984 - GLOCAL

  • Query: a set of metadata from the event modelSimple 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)

    Refinement and navigation mechanisms Query answering produces a ranked list of pointers to the event netRefinement through hyperspace navigation (graphics, interfaces)NEM Concertation meetingBrussels, Feb. 3-4 2010FP7 248984 - GLOCALGLOCAL SEARCH

  • Which are the enabling technologies?Event modelling (media & knowledge)Event instantiation (matching models to reality: create, evolve and maintain events)Event population (effortlessly attaching media to events)Event sharing (sharing event structures and contents)Event-based indexing and search (using events to access media)Event-based interfacing (putting the user in the loop)GLOCAL TECHNOLOGIESNEM Concertation meetingBrussels, Feb. 3-4 2010FP7 248984 - GLOCAL
