Study Notes
Semantic Technologies and IoT Data Processing
- The Internet of Things (IoT) generates data across multiple verticals, making interoperability and integration of IoT data challenging.
- Semantic Web provides reasoning engines and tools to analyze and link massive amounts of IoT data meaningfully.
- Complex event processing techniques search for dependencies and patterns in streaming IoT data to create real-time insights.
- MapReduce programming approach is used to distribute and process large datasets across multiple databases.
- Linked Data creates a global web by semantically linking and integrating information across domains.
- Linked Data refers to machine-readable information published on the web connected to external datasets from different sources.
- RDF (Resource Description Framework) syntax encodes web resources and data in triples, representing subjects, predicates, and objects.
- RDF allows for unidirectional relationships between resources, creating a connected graph of data.
- RDF data storage systems include centralized and distributed systems, with benefits and limitations for each approach.
- DBPedia project aims to extract structured content from Wikipedia and make it available in RDF, enhancing user experience in accessing information.
- RDF Schema (RDFS) is used to define hierarchical classes representing categories of things, allowing for data abstraction and interoperability in IoT.
- Semantic Web facilitates the interpretation of semantic data captured from various sources and sensors in the IoT world.
