BIG DATA
Data so large and complex that it becomes difficult to process using traditional data processing applications.
My research group looks at personal (little)-big data.
Active in the area since 2006.

Extreme Lifelogging
A Personal Awareness Engine (a second memory) that knows everything about you. It is
there to help you, but never to replace an organic memory.
Using body-worn and external sensors.

A ONE YEAR LIFELOG
• 2 million wearable camera images
• Video / audio (hundreds/thousands of hours)
• 3.9 million location points
• Hundreds of millions of sensor readings (accl, WIFI, bluetooth, etc…) to understand the person better
• Information access, creation and communication to model semantic memory
? Semantics ?
Assumption: All data is potentially useful.

The challenge is to extract meaning from the sensor data.
