Google's introduction of the Knowledge Graph is probably the most important thing the company has done in years.

Sure, Android now dominates the smartphone market
and Google+ was also a major — if unsuccessful
— move. But those plays are chiefly intended to feed back into the company's core product, and by far its biggest money-spinner: search.
I've not had the chance to play with it yet, but, if it works as described, the Knowledge Engine really is a step towards the next generation of search and of computing as a whole. You could even call it an artificial intelligence move: computers and the web cannot display intelligence without a genuine understanding of context and relationships.
The idea takes Google Search way beyond its main direct rival, Bing. However, Google's biggest opponent right now is Facebook. Facebook is trying to make itself the default point of entry to the web, and Google doesn't want to lose that status. There's too much advertising money at stake.
Although the Knowledge Graph has clearly been under development for a long time, the timing of the announcement — less than two days before Facebook's IPO — is unmistakeably competitive.
Calling it the Knowledge Graph is also a dead giveaway. Facebook's relational understanding is all based on human interactions, recorded and exploited through its Open Graph. Google+ was an attempt to play catch-up, but the Knowledge Graph exploits the enormous amount of data that is not necessarily user-related.
Essentially, this is Google playing to its core strengths, rather than playing by its rivals' rules.
Is privacy relevant?
That's not to say the Knowledge Graph and Google's social graph (as they refrain from calling it) won't both feed into the results the user sees, but this latest move seems to be nothing more and nothing less than Google hewing to its original aim: organising the world's information.
The Knowledge Graph is a major evolution for search, it's a step towards the semantic web, and it should make the web easier to use and more useful. Frankly, if you can't already tell from my tone, it's all rather exciting.
