W3C Semantic Sensor Networks: Ontologies, Applications, and Future Directions

  1. 1. IERC AC4 Semantic Interoperability Workshop 19-20 June 2012, Venice, Italy co-located with IoTWeek 2012W3C Semantic Sensor NetworksOntologies, Applications, and Future Directions Cory HensonOhio Center of Excellence in Knowledge-enabled Computing (Kno.e.sis ) Wright State University, Dayton, Ohio, USA 1
  2. 2. Once upon a time, there was the Web 2
  3. 3. … and then it grew (ca. 2012) 3
  4. 4. Who or what is the culprit? User generated content, new types of media, etc. 4
  5. 5. A cross-country flight from New York to Los Angeles on aBoeing 737 plane generates a massive 240 terabytes of data - GigaOmni Media What happens when all THINGS go online? (sensors, devices, and appliances begin to publish data) 5
  6. 6. What happens when all THINGS go online?(sensors, devices, and appliances begin to publish data) 6
  7. 7. How are machines supposed to make senseof this noisy, ambiguous, heterogeneous, deluge of data? RDF OWL
  8. 8. Semantic Web (according to Farside) Concrete Facts Resource Description Framework lives in General Knowledge Web Ontology Language has pet Person Animal has pet is a is a“Now! – That should clear up a few things around here!” 8
  9. 9. 9
  10. 10. ~ 50 Billion Statements 10
  11. 11. SW is now moving from academia into industry 11
  12. 12. Apple Siri WatsonIn the last few years, we have seen many successes … Knowledge Graph 12
  13. 13. 13
  14. 14. Now, what about the Sensor Web? 14
  15. 15. Sensor systems are too often stovepiped 15
  16. 16. We want to set this data freeWith freedom comes responsibility1. discovery, access, and search2. integration and interpretation 16
  17. 17. Introducing the Sensor Web Enablement (SWE) 17
  18. 18. Introducing the Sensor Web Enablement (SWE) 18
  19. 19. We want to set this data freeWith freedom comes responsibility1. discovery, access, and search2. integration and interpretation 19
  20. 20. So, again …How are machines supposed to make sense of thisnoisy, ambiguous, heterogeneous, deluge of data? Semantic Sensor Networks (SSN) RDF OWL 20
  21. 21. SSN Ontology(i.e., General Sensor Knowledge) 21
  22. 22. SSN Ontology(i.e., General Sensor Knowledge) 22
  23. 23. SSN Ontology(i.e., General Sensor Knowledge) 23
  24. 24. Semantic Annotation of SWE (backwards compatible) 24
  25. 25. Adoption of SSN 25
  26. 26. SSN Use Cases 26
  27. 27. Linked Sensor Data(~2 Billion Statements) 27
  28. 28. Sensor Discovery ApplicationQuery w/ location name to find nearby sensors 28
  29. 29. Interpretation (or abstraction/explanation)of sensor data 29
  30. 30. Applications of SSN Weather Rescue Healthcare 30
  31. 31. 50% savings in sensing resource requirementsduring the detection of a blizzardorder of magnitude resource savings betweenstoring observations vs. relevant abstractions 31
  32. 32. Weather ApplicationSECURE: Semantics-empowered Rescue Environment (detect different types of fires) 32
  33. 33. Mobile app to help reduce re-admission ofpatients with Chronic Heart Failure 33
  34. 34. Passive Monitoring Phase Observed Symptoms Possible Explanations • Abnormal heart rate • Panic Disorder • Clammy skin • Hypoglycemia • Hyperthyroidism • Heart Attack • Septic Shock Electronic Medical Record Health Alert• Patient has history of Heart Disease • Check phone for instructions 34
  35. 35. Active Monitoring Phase Are you feeling lightheaded? yes Are you have trouble taking deep breaths? Observed Symptoms Possible Explanations • Abnormal heart rate • Panic Disorder yes • • Clammy skin Hypoglycemia • Lightheaded • Hyperthyroidism Do you have low blood pressure? • Trouble breathing • Heart Attack • Low blood pressure • Septic Shock yes Have you taken your Methimazole medication? no Electronic Medical Record Health Alert• Patient has history of Hyperthyroidism 1. Take medication: Methimazole• Patient has prescription for Methimazole 2. See doctor: how about Tues. @ 11am? 35
  36. 36. IERC AC4 Semantic Interoperability Workshop 19-20 June 2012, Venice, Italy co-located with IoTWeek 2012In the next century, planet earth will don an electronic skin. It will use theInternet as a scaffold to support and transmit its sensations. This skin isalready being stitched together. It consists of millions of embedded electronicmeasuring devices.
