Citizens can act as sensors to connect with governments and help the latter understand their wishes and needs
Technologies
GIS Applications
Web and Mobile Apps
Typical Use Cases
Incident Reporting
Suggestions & Comments
Use of Social Media
Tweet to government
Access/post in Facebook pages etc.

7. IoT architectures deal with the proliferating «Social» Sensors
IoT and Social Media
Social Media provide millions of insights on human activity and behaviour during emergencies and security incidents
Examples: London Riots (Twitter), Egypt (Twitter/Facebook), but also «Sandy» Storm (20M Tweets, 10 Instagram photos / sec)
Relevant Technologies: Sentiment Analysis, Community Tracking, Rumour Spreading Detection,...) - Used in several industries (marketing, branding, finance...)
IoT architectures and technologies support «Social» Sensors (as Virtual Sensor)

10. SMART System Overview

11. SMART Edge Nodes Edge Node: SMART Point of Presense
Provides real-time information from the city:
Perceived from the environment (sensors)
Filtered from social networks
Retrieved from the linked data cloud
Inferred by fusing the above into higher-level events

12. Searching «Social» Feeds – Smart Reduce System
Real-Time Distributed Architectures
Storm + Terrier.org
SmartReduce Prototype
Benchmarking (Performance & Scalability)

13. SMART Applications: Live News
“What is happening now?”
“Which places are crowded?”,
“What are the specific trends in the city?”
“Where are riots and fights happening?”
Answers = Multimedia streams mixing sounds/images with textual data stemming from sensors and metadata steams (including social networks)
Deployed at City of Santander

14. SMART Applications: Security & Surveillance
Detect people and/or scenes that could be considered as suspicious across certain times and urban locations
Data Streams from Cameras, Mics and Social Networks
Deployed at City of Santander

15. SMART Applications: Build Your Own SC Scenario
JSR 168 (Java Portlets) compliant editor
Sensor and Social Sensor Driven Portlets and mashups
Customized Portal Developments for Smart City Authorities
Authoring tool for SMART Cities Development
Deployed at Santander, Athens, Glasgow

16. Semantic Interoperability
Alternative Approach: Standardized Semantic Modelling of «Social» Sensors
Semantic Interoperability
Distributed and Heterogeneous Data Sources
Diverse Data Streams
Common Semantics Needed
Solution: Semantic Annoitation (W3C Ontology)
Reasoning Algorithms
Intelligent Selection & Filtering of Sensors
Intelligent Selection & Filtering of Sensor Data
Use of Reasoners
RDF/OWL Ontology (W3C SSN + Linked Data)
Semantic Standards for sensors provide a uniform way for representing and reasoning over heterogeneous data streams

18. Conclusions
Social Media Processing can provide millions of insights on people and things attitude and behaviour
«Social» Sensors is a prominent Virtual Sensor in the scope of IoT applications
IoT architectures make provisions for the integration of Socia Media data
Semantic Interoperability of Social Media Streams is a key for their dynamic discovery and use
