Emphasising Relationships in the BBC's Data Using Technologies of the Semantic Web
summary
Claim: using RDF and ontologies actually links BBC data silos into a usable knowledge layer. Tools shown: SPARQL queries against a dbpedia endpoint using rdflib and SPARQLWrapper; export/import with graph stores; mention of AWS Neptune preview and JanusGraph hybrids. Built artifact: a Content Graph that ingests PIPS metadata, powers News app topic tags and recommendations, and reuses the Linked Data Platform (World Cup/2010 2012). Live demo returns a single cover‑band result and a failed live demo run, highlighting practicality and scaling and provenance limitations.
