What if we could evolve our web of individual documents and data to a web of interlinked knowledge, a web where machines can automatically combine data from multiple sources and draw conclusions from it? The Semantic Web technologies from W3C enable us to make sense of the data wilderness on the web and unlock the full potential of the data treasures hidden in it.

In this talk, we will see how RDF enables us to formally describe the meaning of data and how such data can be queried with SPARQL. We will look at how OWL lets us make more expressive statements about the world, so that a computer can logically reason about it and infer new information. We will demonstrate these technologies by showing how they can be used to query seemingly incompatible data sets as if they were one and letting a computer draw logical (and perhaps surprising) conclusions for us.

Contains: 'retro' technology, linked data, fundamental properties of the web, and Donald Trump's opinion on PHP frameworks.

I loved the talk. I also loved the examples you gave about Donald Trump and CakePHP, It made it fun and interesting. No one likes a boring powerpoint without some fun in it.

Personally, the talk was valuable to me because I work as a developer in a Data-Centric company and it was nice to get a proper explanation for all the buzzwords which I usually hear in the office like RDF/Ontologies, Triples, etc.

As a point of improvement, I think it will be nice to point out more practical ways in which the Semantic Web technology can be used in our everyday life

Thanks once more for the talk. It was really helpful!

Great talk. With some good fun. The build up was great and easy to follow. Also very strong to show the downsides of the technologies. It got me informed and excited about these technologies. The crowd participation slide felt a bit negative with the whole "trust nothing" conclusion. Maybe add something to counter that negativity? like sharing a heavily moderated rdf source?

All in all a great talk. Thank you for giving it and sharing your knowledge.
