Assisting IoT Projects and Developers in Designing Interoperable Semantic Web of Things Applications
- 1. Assisting IoT Projects and Developers in Designing Interoperable Semantic Web of Things Applications 8th IEEE International Conference on Internet of Things (iThings 2015) 11-13 December 2015, Sydney, Australia Amelie Gyrard, Insight, Ireland Christian Bonnet, Eurecom, France Karima Boudaoud, I3S/CNRS, France Martin Serrano, Insight, Ireland
- 2. Agenda • Introduction & Motivation Combining Semantic Web technologies and Internet of Things (IoT) • State of The Art & Main challenges The Machine-to-Machine Measurement (M3) Framework • Contribution: Semantic Web of Things (SWoT) generator • Conclusion & Future work 2
- 3. How to build interoperable IoT applications? 3 Innovative applications => Interoperability on data rather than protocols
- 4. How to describe data and get additional information? => Taking inspiration from the Web Automatically built by machines
- 5. “Semantic Web of Things: an analysis of the application semantics for the IoT moving towards the IoT convergence” [Jara et al. 2014] How to apply semantic web technologies to Internet of Things? Global interoperability ⇒ How to provide a common description to build interoperable applications? ?Common description Common App. Protocol Device Abstraction Common Nwk. Protocol 5 • Machine-understandable data • Describe data with common vocabularies • Reuse domain knowledge • Link to other data • Ease the reasoning
- 6. Interoperable semantic-based IoT applications Interoperable IoT knowledge base Interoperable reasoning The Machine-to-Machine Measurement (M3) Framework 6 http://sensormeasurement.appspot.com/ Interoperable security knowledge base Lessons learnt from this catalogue of domain knowledge
- 7. Semantic Web of Things (SWoT) generator Template used in 3 steps: 1) Designing phase 2) Development phase 3) Running phase SWoT template => Benefits: No need to learn semantic web technologies IoT Application generate build use IoT developers 7
- 8. SWoT Generator: Designing phase 8 * Design semantic based IoT applications * Domain where is deployed the sensor, not the applicative domain - Sensor - Domain - Rules for M3 converter - Rules to get high-level abstractions - Domain ontologies - Domain datasets - SPARQL query SPARQL query SWoT template dataset (RDF):
- 9. SWoT Generator: Development phase IoT developers SWoT template 1) Load: - M3 ontologies - M3 IoT data - M3 datasets 4) Get M3 suggestions or high level abstractionsSTEPS BEFORE Get template 3) Execute M3 SPARQL query + SPARQL engine SemanticWeb Framework 2) Execute M3 rules + reasoning engine 9
- 10. SWoT Generator: Running phase 10 Reasoning engine Interoperable semantic IoT data Standardizing Generic Cross-Domain Applications in Internet of Things [Gyrard et al. 2014] Demo paper: Helping IoT application developers with Sensor-based Linked Open Rules [Gyrard et al. 2014]
- 11. SWoT template: interoperable domain knowledge • Need to have the set of files generated in the template compatible with sensor data Ontologies + datasets + rules + sensor data Domain knowledge structured in the same way Domain ontologies Domain datasets Rules Interoperable IoT Application Provide sensor data SWoT templateUnified IoT data Produce 11
- 13. Evaluating the SWoT generator • 7 different datasets with different kind of sensor data • 22 templates to build semantic-based IoT applications – Interpret data – Cross-domain applications http://sensormeasurement.appspot.com/?p=tourism http://sensormeasurement.appspot.com/?p=transport http://sensormeasurement.appspot.com/?p=restaurant http://sensormeasurement.appspot.com/?p=home http://sensormeasurement.appspot.com/?p=naturopathy 13
- 14. Evaluating the SWoT generator • Do we have templates covering the most popular IoT use cases? http://www.sensormeasurement.appspot.com/?p=m3_scenario • Adding a new template? Less than 1 day Depends on whether we already have the interoperable domain knowledge 14
- 15. Conclusion: Semantic Web of Things (SWoT) generator 15 • Encourage IoT developers to integrate semantic web technologies to reduce development cost: Semantically annotate IoT data Interpret IoT data Reuse domain knowledge available on the Web Interoperability among IoT applications and applicative domains => This work is reused within the FIESTA-IoT EU project
- 16. ⇒ Our proposed approach Future work Composition of templates Global interoperability Common description Device Abstraction Common App. Protocol Common Nwk. Protocol 16 More templates inspired from EU project’s scenarios Linked Open Services
