IPTC SemWeb Working Group

• Making use of Semantic Web technologies for news– Leverage technologies developed by others

• The work falls into two main areas:– Models

• Determine what aspects of news to represent– Formats

• The details of how to represent the news• Using RDFa, microformats, Linked Data, microdata

IPTC’s Semantic Web Agenda

At this meeting we will discuss

• Update on rNews since 1.0• Linked Data for News• W3C semnews Community Group


The Semantic Web and Linked Data

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

Update rNews 1.0


http://dev.iptc.org/rNews

• rNews 1.0 approved 2011/10• Update from New York Times• Who else is adopting rNews?

rNews Next Steps

• Market rNews to drive adoption– Identify opportunities to promote rNews (and the IPTC)– Create tools for validating rNews implementations

• Continue to work with rNews consumers and producers– Update mapping of rNews to schema.org– Consider feedback from implementations

• Publish rNews 1.1 in summer, if required


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– Wikipedia announced Wikidata http

://meta.wikimedia.org/wiki/Wikidata

• We proposed 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– Identified Freebase as candidate, experiment with mappings
