Yo, what’s an entity? Google acquires Metaweb

"Entities are smarter than words," says Metaweb on their YouTube video.

Semantic web takes another step forward.  This Metaweb video has a good explanation in layman’s terms about what an entity is.  Uses the barcode analogy for unique IDs.

Also, check out this opinion from a Microsofter with ties to the IC, Lewis Shepherd.  He calls it the “semantic war”… a “global web-scale war now gearing up between major computing powers Google and Microsoft, in a race for performance and innovation in semantically-enabled decision support.”  Whoa.
