ChallengesChallenges

Typical organization of the personal informationTypical organization of the personal information



• Semantically-related information is fragmented across media and directories

• A rigid logical and/or physical hierarchy is used for categorizing the information • Spatial and temporal information, essential to events in the physical world, are not considered necessary and are therefore, unavailable

• Patterns in the data that may answer the “how?” and the “why?” are lost

ChallengesChallenges



Event based approach

Data is related to events ( e.g. in our life)

An “Event” is an occurrence or happening of significance that can be defined as a region or collection of regions in spatial-temporal-attribute space

Most data and information is related to events.Temporal and Spatial organization is a fundamental mechanism

used by people.People organize information and data around events and entities.Entities are a special case of events.

eVitae System Highlights

• Integrated multidimensional view of the events (spatial and temporal spaces)

“exploring” the information space

• Events Overview in space-time Event details

• Egocentric view of the events (fisheye lens) !! focus + context !!

• Different granularities of time and space .. Centuries Decades Years Months..

.. Continents Countries States Cities ..

Conclusions

‘Events’ are useful in unifying context and multifarious data.

Why and How are naturally answered if an application is modeled using events.

Event-based indexing and organization of data provides both information and experience.

eChronicles have many diverse applications.
