Perspectives on information, technology and people

27 September 2022  1100-1215

This week we will consider data, information, knowledge, and meaning. How do they fit with one another?

Let's begin by learning something we didn't know we didn't know.

① info world

We will start each session with one of us standing before the assembled group and introducing us to an "information world" that they are familiar with, but one that may well be new to the rest of us.

This will be voluntary: there will be no one necessarily assigned to do this weekly, though we hope everyone would want to share of themselves by taking advantage of the opportunity.

"This is an information war," says Omar Tawakol, the boss of BlueKai, a data broker, which tracks users online and sells that intelligence to companies. "This is 100% about having more information about the customer and being able to generate more commerce as a result of it." ... BlueKai, for example, compiles around 1 billion profiles of potential customers around the world, each with an average of 50 attributes.
