Fivethirtyeight.com is full of interesting content. Sports and politics of
course, but also science, economics and culture (read about the Batman-Superman
bromance here).
And now, FiveThirtyEight has a coaching tip for radio.
OK, not exactly.
But their recent post about the most frequently used phrases by Presidential
Candidates Hilary Clinton and Bernie Sanders got me thinking about how quantifying talents’ most oft-used subject matter – the fascinating and the
irrelevant – could be a handy coaching tool.
FiveThirtyEight’s Clinton-Sanders piece uses a statistical
procedure call dtf-idf which compares the frequency of words or phrases in a document, a speech, a body of speeches, etc. to their use in general.
Reading about dtf-idf was fascinating if geeky, though I was looking for a less
“math-intensive” alternative to use as a coaching tool.
Enter Document Classification often used in library science to assign a piece of work to one or more
categories - geography, history, science, etc.
Subjecting a show to Document Classification could look like this:
The process can be done via an algorithm (as in text classification used for spam detection) or intellectually
(manually) through user-defined criteria – the latter being perfectly fine for coaching
purposes.
Plus you can quickly turn your data into a visual to help
you make your point. Two shows might break out like this:
Roadmap 2016 – A&O&B’s annual client online
perceptual – again confirmed listeners’ top reasons for picking one station
over a competitor: plays the best music, makes me feel good when I listen, fun
DJs who sound like and talk about things like my friends.
Obviously some of the bars above meet the listener criteria
better than others – and that’s the point.
One of my favorite “Radio Algebra” formulae is that EV > CL – that is, the
“entertainment value must be greater than the cost of listening.” The greater that differential is, the more
powerful your show and station are.
A Document Classification visual can help you make that
point.
