Ontology-based Multi-Agent Platform For Sensor Data Integration and Sharing
Sensor Web Enablement (SWE)： • SOS：Sensor Observation Service • SAS：Sensor Alert Service • SensorML：Sensor Model Language • O&M：Observations & Measurements • …….
SOS provides standard operations to access sensor information, including observation data and sensor descriptions. Operations: • getCapabilities • describeSensor • getObservation • …….

SWRL (Semantic Web Rule Language) : a standard language which uses rules (i.e., if-then statements) to express knowledge in ontologies
ObservationOffering (?offering) ∧ hasObservedProperty (?offering, CO) ∧ hasUOM (CO, PPM) ∧ hasObservation (?offering, ?o) ∧ Observation (?o) ∧ hasValue (?o, ?v) ∧ moreThan (?v, 30) → SevereCO (?o)
(any string started with ? is an instance that belongs to the class)
