2 Motivation Existing social mining practices threaten social cohesion surveillance has become increasingly privatized, commercialized and participatory, Julie E. Cohen

3 Research Question How to design an open, decentralized, privacy-preserving & participatory system to provide ubiquitous social mining services engineered as public good Social mining: the process of discovering information from data sensed in one or more social environments so that a social phenomenon is understood or a societal problem is tackled.

4 Approach Introduction of a modular & compositional approach so that citizens participate during building lifecycle & later on Why? Designing extensible & reusable social mining processes via compositional data flow of sensors simplifies application development A design principle with a potential to simplify crowd-sourcing activities & increase engagement of building communities.
