Download as PPTX, PDF5 likes2,580 views
The document discusses the IERC AC4 Semantic Interoperability Workshop held in June 2012, focusing on semantic sensor networks and their applications in various fields. It emphasizes the challenges of managing the vast amount of data generated by connected devices and the importance of semantic web technologies for data interpretation. Key topics include the Sensor Web Enablement (SWE), the Semantic Sensor Networks (SSN) ontology, and practical use cases in healthcare and environmental monitoring.

- 2. Once upon a time, there was the Web 2
- 3. … and then it grew (ca. 2012) 3
- 4. Who or what is the culprit? User generated content, new types of media, etc. 4
- 5. A cross-country flight from New York to Los Angeles on a Boeing 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. What happens when all THINGS go online? (sensors, devices, and appliances begin to publish data) 6
- 7. How are machines supposed to make sense of this noisy, ambiguous, heterogeneous, deluge of data? RDF OWL
- 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
- 10. ~ 50 Billion Statements 10
- 11. SW is now moving from academia into industry 11
- 12. Apple Siri Watson In the last few years, we have seen many successes … Knowledge Graph 12
- 13. 13
- 14. Now, what about the Sensor Web? 14
- 15. Sensor systems are too often stovepiped 15
- 16. We want to set this data free With freedom comes responsibility 1. discovery, access, and search 2. integration and interpretation 16
- 17. Introducing the Sensor Web Enablement (SWE) 17
- 18. Introducing the Sensor Web Enablement (SWE) 18
- 19. We want to set this data free With freedom comes responsibility 1. discovery, access, and search 2. integration and interpretation 19
- 20. So, again … How are machines supposed to make sense of this noisy, ambiguous, heterogeneous, deluge of data? Semantic Sensor Networks (SSN) RDF OWL 20
- 21. SSN Ontology (i.e., General Sensor Knowledge) 21
- 22. SSN Ontology (i.e., General Sensor Knowledge) 22
- 23. SSN Ontology (i.e., General Sensor Knowledge) 23
- 24. Semantic Annotation of SWE (backwards compatible) 24
- 25. Adoption of SSN 25
- 26. SSN Use Cases 26
- 27. Linked Sensor Data (~2 Billion Statements) 27
- 28. Sensor Discovery Application Query w/ location name to find nearby sensors 28
- 29. Interpretation (or abstraction/explanation) of sensor data 29
- 30. Applications of SSN Weather Rescue Healthcare 30
- 31. 50% savings in sensing resource requirements during the detection of a blizzard order of magnitude resource savings between storing observations vs. relevant abstractions 31
- 32. Weather Application SECURE: Semantics-empowered Rescue Environment (detect different types of fires) 32
- 33. Mobile app to help reduce re-admission of patients with Chronic Heart Failure 33
- 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. 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. IERC AC4 Semantic Interoperability Workshop 19-20 June 2012, Venice, Italy co-located with IoTWeek 2012 In the next century, planet earth will don an electronic skin. It will use the Internet as a scaffold to support and transmit its sensations. This skin is already being stitched together. It consists of millions of embedded electronic measuring devices.
