  6. 6. BigDataq  A sensor can do (implements) sensing: that is, a sensor is any entity that can follow a sensing method and thus observe some Property of a FeatureOfInterest. q  Sensors may be physical devices, computational methods, a laboratory setup with a person following a method, or any other thing that can follow a Sensing Method to observe a Property. SSN Sensor
  7. 7. BigData q  Collects together measurement properties (accuracy, range, precision, etc) and the environmental conditions in which those properties hold, representing a specification of a sensor's capability in those conditions. SSN Measurement Capability
  8. 8. BigData q  An Observation is a Situation in which a Sensing method has been used to estimate or calculate a value of a Property. q  Links to Sensing and Sensor describe what made the Observation and how; links to Property and Feature detail what was sensed; the result is the output of a Sensor; other metadata gives the time(s) and the quality. q  Different from OGC’s O&M, in which an “observation” is an act or event, although it also provides the record of the event. SSN Observation

Do you have low blood pressure? yes •  Abnormal heart rate •  Clammy skin •  Lightheaded •  Trouble breathing •  Low blood pressure •  Panic Disorder •  Hypoglycemia •  Hyperthyroidism •  Heart Attack •  Septic Shock Observed Symptoms Possible Explanations no Active Sensors – blood pressure, weight scale, pulse oxymeter Demo: http://www.youtube.com/watch?v=btnRi64hJp4 SSN Applications: Health Care
  20. 20. BigDataData Processing and Seman1cs for Advanced Internet of Things First responders have limited time to analyze sensor (on and around them) observations. Fire fighters need to combine prior knowledge of fires and its behavior, extinguishers, and floor plan of the building for rescue strategy and operations. There are a variety of sensors used to monitor vitals of firefighters, location, and poisonous gases. O2 Heart rate CO CO2 GPS Accelerometer Compass Footsteps There is a team of them making it further difficult for analysis Semantic Web allow us to describe the domain, sensors, and first responders -- apply reasoning techniques to derive actionable insights Sensors on each responder provides different view of the event and they need to register dynamically as the firefighters arrive.
