What IBM, the Semantic Web Company, and Siemens are doing with semantic technologies

Defining semantics is a matter of semantics, not less so in the Big Data space.

The Semantics conference is one of the biggest events for all things semantics. Key research and industry players gathered this week in Leipzig to showcase and discuss, and we were there to get that vibe.

Graphs are everywhere: we have social graphs and knowledge graphs and office graphs, and in the minds of most these have been associated with Facebook and Google and Microsoft. But the concept of Knowledge Graphs is broader and vendor-agnostic.
