Moving beyond a web of documents

To a web of data

Semantic Web technologies

extend today’s web with• machine readable information• links between data and services

Also known as “The Giant Global Graph”, “Web 3.0”, “A Web of Things” …

There are different theories about what it is and how to get there.

Semantic Web and Linked Data

rNews: News Metadata in HTML• One goal

– Promote the creation of better, more accurate tools for working with news on the web

– By adding news metadata to HTML

• (At least) three approaches– Microformats

• conventions for using standard HTML• to add labels to indicate the meaning of markup

– RDFa• alter your HTML document to use non HTML attributes• to insert RDF triples to indicate the meaning of markup

– Microdata• a proposed set of structures within HTML5• to associate name value pairs with scoped items in HTML

Linked Data for News

• IPTC NewsCodes available as Linked Data– Connect related data across the web using URIs, HTTP & RDF

• Followed the Linked Data principles, as specified by TBL– Use URIs as names for things – Use HTTP URIs so that people can look up those names. – When someone looks up a URI, provide useful information,

using the standards (RDF, SPARQL) – Include links to other URIs, so that they can discover more

things

More Linking

• The current IPTC Linked Data only links between IPTC NewsCodes– We’ve experimented with mapping to DBpedia– We’ve discussed mapping with Freebase

• We propose to explore linking to non-IPTC resources– Make the IPTC NewsCodes linked data more useful– Potential for IPTC to become a “hub” in the Linked Data network– Identify candidate resources, experiment with mappings– Report findings at the London meeting
