2. Agenda
• Introduction & Motivation
• Contribution:
LOV4IoT: Linked Open Vocabularies for Internet of Things
LOV4IoT RDF dataset to make statistics
Extracting domain knowledge
• Use Case & Evaluation
• Conclusion & Future work
2
4. Motivation: How to reuse domain knowledge already
designed in previous IoT applications?
Classify InteroperabilityCollect
How to exploit the domain knowledge
already available on the Web
and make it interoperable?
5. Basics: Semantic Web Technologies
• Domain knowledge already structured and designed
• Ontologies used to share and reuse the domain
knowledge
6. Descriptions

• LOV4IoT: Linked Open Vocabularies for Internet of Things
(LOV4IoT)
• an extension of the Linked Open Vocabularies (LOV) catalogue
o Numerous ontologies relevant for IoT were not referenced yet due
to a lack of unknown semantic web best practices
• LOV4IoT: a dataset referencing more than 300 ontology-
based projects relevant for IoT
o Ontologies, Datasets, Rules, Technologies, Sensors and
Domains

13. Extracting domain knowledge from LOV4IoT
• Extracting a dictionary to unify IoT data
• Extracting IoT domains
• Extracting rules to interpret data
• Extracting knowledge from ontologies and datasets
15. LOV4IoT Use Case:
Semantic Web of Things (SWoT) Generator
• Assisting developers in designing semantic-based IoT
application by generating a template
Our dictionary classifying sensors
19. Conclusion & Future work
19
• LOV4IoT references more than 300 ontology based IoT
projects in numerous domains
• LOV4IoT encourages the reusability of the domain
knowledge available on the Web.
• Future Work:
Automatically update LOV4IoT
Validator to improve interoperability among existing
ontologies referenced within LOV4IoT
