2 The Web is about links… The Semantic Web is about the relationships in those links Dan Brickley

3 Vision of Semantically Linked Data The Network of Collaborative Knowledge A web of data that can be intelligently processed by machines delivering an environment that: Intelligent Solves Problems Relevant Answers Questions Contextual Easily Searchable Interconnected Let Information follow you “The next generation of information workers will expect a highly visual, connected, contextual information workplace they can take anywhere.” - Forrester

10 Linking Data Resources User Data Ontologies RDF Query & results Structured & Unstructured Data Sources

11 It’s Not Just about “Linking” Integrate domains of knowledge through common vocabularies (ie SKOS) Manage relationships between collections of images and associated metadata RDF as flexible and extensible data model supports powerful search and end-user discovery of related content Rich platform for data integration, data repurposing, and better quality control and classification Semantic Aggregation & Navigation of Data

20 Why is Oracle Spatial unique in Semantics Data Management? Oracle 11g is the only commercial database with native RDF/OWL semantics capability. Can readily scale to ultra-large repositories (+1 billion) Growing ecosystem of 3 rd party tools partners Leverages Oracle Partitioning and Advanced Compression. RAC is also supported. Semantics customers expect to deploy very large servers
