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.

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)

6. What happens when all THINGS go online?
(sensors, devices, and appliances begin to publish data)

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

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

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)

20. So, again …
How are machines supposed to make sense of this
noisy, ambiguous, heterogeneous, deluge of data?
Semantic Sensor Networks (SSN)
RDF OWL

21. SSN Ontology
(i.e., General Sensor Knowledge)

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?

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.
