Word clouds done right

By Felix Salmon
October 31, 2011

Jacob Harris is absolutely right to hate word clouds. You take a long and complex text, and then you boil it down to a group of individual words, with the most-used words being the biggest? That’s just silly. “Reporters sidestepping their limited knowledge of the subject material by peering for patterns in a word cloud,” he says, is “like reading tea leaves at the bottom of a cup”. Word clouds are crude, inaccurate, misapplied, and place the onus of understanding onto the reader.

But there’s one place where word clouds are I think both useful and accurate — and that’s when a pollster has asked a group of people to say the one word they would use to describe X. Here, for instance, is the word cloud generated when a Reuters/Ipsos poll asked Republican voters for the first word that came to mind after watching the weird Herman Cain “smoking ad”:

And here’s the word cloud from the latest Kauffman poll of econobloggers:

Here the size of the words is interesting, but more germane is the overwhelming negativity of the vast majority of words used. There’s a couple of tiny good ones in there — “rebounding” us up by the Canadian border, and “bounceback” is in the Bay Area somewhere — but they’re in a distinct minority.

Incidentally, that Kauffman poll has some fascinating responses elsewhere, too. Check out the sudden enormous popularity of NGDP targeting:

There’s also a very high degree of skepticism when it comes to how good colleges are at teaching kids useful stuff.

The bar charts here are again an effective way of communicating information. Things like chart types and word clouds are tools, and you have to know which tools are best used in various different circumstances. And while word clouds are usually stupid, sometimes they can be exactly right.

“Fluffy?” (which appears about where MS would be)

I would stop talking to econobloggers who refer to our economy, good times or bad, as “fluffy”.

You ask a bunch of conservative economists (conservative even in context of a conservative field) if college education is signalling or actual learning and you expect the results to be anything else?

X, next thing you know you’ll be amazed that engineers think anyone graduating with a non-STEM degree is a parasite, even though their own salary is higher solely because of government subsidies.

Well, actually education has economists in a pickle, because a number of economic traditions argue that college must be “rational” as an “investment”.

I think most liberals would also be in the “about half” category. How many people really think that you spend 4 years on skills that are actually useful in the job market?

“How many people really think that you spend 4 years on skills that are actually useful in the job market?”

How many people would really want to hire your average college freshman as an assistant? You would spend more time baby-sitting them than the “help” would be worth.

In college you learn (or should learn):
* The language in which understanding is communicated in a variety of disciplines.
* The discipline to work independently and think critically.
* General literacy, both in writing and mathematical.

Maybe you take a couple courses that teach material you will use specifically in your first job? But even though learning doesn’t end in college, it is still important to lay the groundwork for what is to come.
