Algorithms and the Filter Bubble, Take 3

[Update 5 April 2015: There is a more recent version of this lecture, presented in September 2014, but it has not been posted yet.]

Title card for "Algorithms and the Filter Bubble"On Monday 7 April, I delivered an updated version of my guest lecture to media students at the University of Technology Sydney (UTS), “Algorithms and the Filter Bubble”. And here it is.

What’s it about? It’s about what we now call — this year at least — “big data” and how that’s changing how the media works, just like it’s changing every other part of society.

I cruise through what all this data is, where it’s coming from, who’s collecting it and where it’s going; what advertisers and media companies and others can do with this data; and some speculation about how this might unfold in the future.

There’s links to all the references over the fold, and you can follow along with the slides (PDF). The recording picks up immediately after I was introduced by the course coordinator, Dr Belinda Middleweek. A transcript may or may not follow at some point in the future.

Some people mentioned that last time it was difficult to follow some of the slides, as the PDF file didn’t show how the builds happened, so I may add a video slideshow version at some point too.

The audience was primarily first and second year students at the beginning of their media studies degrees.

What was left out at the end

I didn’t keep a close enough eye on the time, which is most unprofessional of me, so I had to drop a couple of things at the end of the lecture. So what did we miss?

My planned closing was to speculate a little more about the implications of all this technology — essentially the material covered in references 26 through 30 below.

When advertisers and newsmakers know all about you, including where you are and what you’re interested in, and when robots become so good that they’re able to tailor news and advertising precisely for your interests and current state of mind — what does that mean for political persuasion, and other kinds of persuasion?

Watch the videos of the robots from the US Naval Research Laboratory responding to everyday human speech. Consider Apple founder Steve Job’s comment that the iTunes Store gives you “freedom from pornography”. Consider than in a world of filter bubbles, some news outlets with a political agenda might want to give you “freedom from confusing thoughts”. After all, Apple has already blocked from their App Store an app that provided information on US military drone strikes.

Just where might this go? As I told the media students at the start of the lecture, they are the ones who will be creating this future for themselves and their descendants, not those of us in the second half of our lives.

Talking data mining on ABC Gippsland

Every now and then I end up doing an explainer that starts at the very beginning — like this radio spot about data mining for ABC Gippsland this morning.

Breakfast presenter Gerard Callinan has posted the audio under the title Mapping key strokes. Who’s watching?

For many of us, the idea of going a day without using the internet either at work or at home is almost unimaginable. Have you ever thought what happens to the information that you leave behind when visiting your favourite websites? Every page you visit, every survey you take, every ad you click on builds up a profile which is used by marketing companies and increasingly, political parties to build up a picture about what sort of things you are interested in and how you might be swayed to buy items or even vote in an election.

Here’s a slightly different version of the audio here, with the volume re-normalised — which just means it’s now supposedly at the optimal volume.

I think Mr Callinan got slightly paranoid after he’d read a certain op-ed I wrote earlier this year.

I’m not so sure how well I explained things. This was a live-to-air piece at 0720 AEDT after I’d had just three and a half hours of sleep and a few hours dealing with, um, a very aggressive intestinal problem. So I wasn’t as focused as I’d like to have been.

If I had my time again, I’d have made sure to explain how the advertising embedded in web pages, or the Facebook “Like” buttons, allow those organisations to track you across multiple sites. And I’d have made sure to have a link I could give out for some concise “How to protect your privacy online” guides.
