Overheard: Creating the semantic graph with RDF and OWL

nova_spivack.jpg Now when another application such as App A comes along and looks at App B’s data it can reference App B’s ontology to see for itself what was intended by the “has team” link — it can see exactly what that link implies and what can be inferred by it. It understands how to use App B’s data set, and how to correctly make new links using that data set which are consistent with the meaning of the links it contains.

Nova Spivack, Defining the Semantic Graph — What is it Really?

This is the real point of the Semantic Web open standards — RDF enables data to be represented in a database independent manner, and OWL enables the semantic of that data to be defined in an open machine-understandable way so that other applications can use that data without having to first be programmed to do so. As long as they speak RDF/OWL, applications can use any data they find and lookup the meaning of any data they need to use so they can use the data appropriately.

Overheard: Tim Berners-Lee on social graphing

Technology, Semantic web, Social networking, social graph
tim_berners-lee.gif So the Net and the Web may both be shaped as something mathematicians call a Graph, but they are at different levels.

The Net links computers, the Web links documents. Now, people are making another mental move. There is realization now, “It’s not the documents, it is the things they are about which are important”. Obvious, really…

I called this graph the Semantic Web, but maybe it should have been Giant Global Graph! Any worse than WWW? ;-)

Tim Berners-Lee, Giant Global Graph

Overheard: Definition for Web 3.0



Posted by: Margaret Rouse
Technology, Rdf, Semantic web, Web 3.0, Web 2.0
nova_spivack.jpg “Web 3.0, in my opinion is best defined as the third-decade of the Web (2010 - 2020), during which time several key technologies will become widely used. Chief among them will be RDF and the technologies of the emerging Semantic Web. Essentially, the Semantic Web enables the gradual transformation of the Web into a database.

Web 3.0 is an era in which we will upgrade the back-end of the Web, after a decade of focus on the front-end (Web 2.0 has mainly been about AJAX, tagging, and other front-end user-experience innovations.)”
