1 eVitae: An Event-Based Electronic Chronicle Bin Wu Rahul Singh Punit Gupta Ramesh Jain Experiential Systems Group Georgia Institute of Technology

2 eVitae: An Event-Based Electronic Chronicle Experiential Systems GroupGeorgia Institute of Technology Chronicles An extended account in prose or verse of historical events, sometimes including legendary material, presented in chronological order and without authorial interpretation or comment. A detailed narrative record or report. Uses multiple media streams to record proceedings Edited or logged Is recorded and presented using electronic recording and presentation mechanisms. No legacy of paper/print media Multimedia Electronic Chronicles (eChronicles)

3 eVitae: An Event-Based Electronic Chronicle Experiential Systems GroupGeorgia Institute of Technology My Papers Presentations Photographs Web-Links My Computer Challenges Typical organization of the personal information

4 eVitae: An Event-Based Electronic Chronicle Experiential Systems GroupGeorgia Institute of Technology 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 Challenges

5 eVitae: An Event-Based Electronic Chronicle Experiential Systems GroupGeorgia Institute of Technology 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. Why Events?

6 eVitae: An Event-Based Electronic Chronicle Experiential Systems GroupGeorgia Institute of Technology Event Location: Minneapolis Date: Oct 6, 2003 Related Papers Media : Slides Media : Photograph Name: Cray Lecture Conceptualizing Information As Events: An Example My Papers Presentations Photographs Web-Links Spatial and Temporal information is made prominent Organization of the information transcends media Multiple organizations (including hierarchies) of the information are possible Patterns in the data indicating distribution of attributes over space and time begin to emerge

9 eVitae: An Event-Based Electronic Chronicle Experiential Systems GroupGeorgia Institute of Technology 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 ..

11 eVitae: An Event-Based Electronic Chronicle Experiential Systems GroupGeorgia Institute of Technology 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.
