NPR, NYT, The Guardian

RESTful API with XML, JSON, or ATOM

New revenue opportunities

Uniform access or content silos?

Proprietary schemas

Linking across APIs

Linking to external data sources (e.g. DBPedia, data.gov)

Need for a universal query language

Semantic Web Technologies Semantic Web aka Web 3.0 Linked Data Cloud RDF SPARQL OWL SKOS

Semantic Web Business Case 1 Semantic Search (apple the fruit vs. apple the company) Beyond Google keyword search and PageRank The web as a giant searchable database 3 Content and data exploration through Linking to external data sources (e.g. NewsItem on Apple to DBPedia article to filing on sec.gov)‏ Interesting m e shups 2 Inferencing (Apple>Steve Jobs>iPhone) Semantic Browsing Metadata as facets News I want to read (FOAF interest) ‏

Why RDF? RDF rocks! “ Anyone can say anything about anything” Labeled directed graph Typed (semantic) links Cross-domain entity correlation bridges silos (owl:sameAs) Inferencing RDF myths debunked RDF is a data model RDF is easy: Subject-Predicate-Object Serializations not limited to RDF/XML: N3, Turtle, N-Triples, RDFa A layer on top of XML and RDBMS apps

RDF rocks!

“ Anyone can say anything about anything”

Labeled directed graph

Typed (semantic) links

Cross-domain entity correlation bridges silos (owl:sameAs)

Inferencing

RDF myths debunked

RDF is a data model

RDF is easy: Subject-Predicate-Object

Serializations not limited to RDF/XML: N3, Turtle, N-Triples, RDFa

A layer on top of XML and RDBMS apps

Value Added News Global economic Tsunami hits newspapers. Ad revenues decline. Paid content becomes an imperative. After a decade of free content, readers want to know why they have to pay now. SemWeb enriches content. Findability and relevance. Real value for professional audience.
