Unified Indexing

� Should not use idiosyncrasy of a medium� Video: time, frame number; Text: page, line; ...

� Should be independent of a medium� Should allow indexing into all media

Event hierarchy is the best ‘unified indexing’.

10

Current Indexing Approaches

� Different databases have different indexing� Assets are generated at different time and at different place

and dumped in the ‘warehouse’� No unified indexing approach

Unified Indexing

Meta Index based on Event-graph

11

Event Indexing

Contextual Search

� Context = (person, location, time, situation)� Person = (set of preferences, personal

data)� Situation = (weighted activity history)

� Contextual Search = Search in Context� Contextual Inference = Anticipation
