• Content-based retrieval systems failed so far to provide general-purpose, reliable systems:– semantic gap– content vs. context
• New 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 OBJECTIVES
NEM – Concertation meetingBrussels, Feb. 3-4 2010FP7 248984 - GLOCAL
• 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 peers at local and global level to build
a social intelligence as the way to automate media organization
– The construction of new search paradigms based on the above elements
GLOCAL S&T ISSUES

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)• …
Media populate events:• Events contextualize media (experiential dimension)• Many-to-many relationship (viewpoints):
•One media linked to many events
•One event linked to many media
Linked persons
Linked locations
EVENT(UID)

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 Refinement and navigation mechanisms –Query answering produces a ranked list of pointers to the event net–Refinement through hyperspace navigation (graphics, interfaces)
ExampleEvent: text description What “Soccer match Milan”
Time: temporal range When May 15, 2008
Space: geo location Where Milano, Italy
Entities: actors, objects Who Milan, Beckham
Sample media Which Photo of 1st goal

EXAMPLE: AN EVENT NETWORK…
• 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)

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)
