Semantic approach to Data
      Description
       Christopher Matheus
 Bell Labs Ireland/Alcatel-Lucent
Linked Data & Semantic Web
• Linked Data Principles:
   – URI as names
   – http URI for name lookup
   – provide information about
     the data using RDF
   – link to other data sets
• RDF:
   – Resource Description Framework
   – subject – predicate – object
• RDFS and OWL
   – Ontology Languages
   – Used to define a language of discourse for a domain
Use of Ontologies
•   Data Modeling
•   Define formal “meaning” of terms
•   Solid foundation for common APIs
•   Consistency checking of data
•   Automatically infer implicit information
Potential Value to Dublinked
• Describing Data Sets                           Domains
                                                 • transportation
   – Improve precision of search                         • public
                                                                  • buses
   – Improve conceptual organization                                            • schedules
                                                                                • arrival times

   – Connections between data sets
                                                                     • trains
                                                         • traffic
                                                                     • video cameras

• Describing Data                                                    • volume
                                                                             • motorways
                                                                             • national routes
   – Data models:                                • planning
                                                 • water
      • XML schema                               •…

      • RDB schema
      • RDFS/OWL ontology
   – Inferring implicit information
   – Translating between data sets or data types
      • E.g., location representation, rdb2rdf, xsparql
