CITIZENS AS SENSORS
+ = !
Why not treat information from the citizens
as another type of sensor data?

NERVOUS SYSTEM
FROM FRAMEWORK TO IMPLEMENTATION
10. Multi-Sensory Integration
Combines the information from different sensory systems
Results in coherent representation of the environment
Is prerequisite for adaptive behavior and response to the environment
Decreases sensory uncertainty and reaction times
Characteristics
Mutual feedback between sensory systems
Spatial proximity, temporal proximity, and inverse effectiveness
05.06.2014F.O.Ostermann & S. Schade - AGILE 2014 Conference 10
NEUROSCIENCE PERSPECTIVE
11. Sensor data or information fusion
Focus on
Low-level abstracted sensor data
Data fusion from several but similar sensors
Different but related sensors in close spatial proximity (e.g. robotics)
Less activity on
Integration of heterogeneous sensors covering irregular areas
(hard/soft data integration from disparate sensors)
05.06.2014F.O.Ostermann & S. Schade - AGILE 2014 Conference 11
ENGINEERING PERSPECTIVE
12. Two major principles from
neuroscience and cognitive
science align with core GI-
principles: what is near in space
and time is related
Inverse effectiveness hints at
why outliers might be important
Engineering provides methods
and algorithms

FROM FRAMEWORK TO IMPLEMENTATION
20. • Cue combination
• Causal inference
• Assign likelihoods based on prior knowledge
• Challenges
• Choose relevant data sets (information retrieval)
• Train semi-autonomous system
• Crowd-sourced supervised machine learning
of a stratified sample of DENS perceptions
• Solution?

HOW-TO AND TOOLS
24. 05.06.2014F.O.Ostermann & S. Schade - AGILE 2014 Conference 24
NEXT STEPS
Too specific approaches had little success in increasing interoperability
Risk of failure for over-generic approaches
Stepwise and incremental development methodology
Starting from well examined cases, such as the forest fire or flood
examples for the initial set-up of a possible solution
Moving into new areas such as urban environments
Move to cloud processing
