Sarcasm-detecting software wanted

Filed under: Media, Technology — Tags: , , , , — Nicholas @ 09:02

Charles Stross discusses some of the second-order effects should the US Secret Service actually get the sarcasm-detection software they’re reportedly looking for:

… But then the Internet happened, and it just so happened to coincide with a flowering of highly politicized and canalized news media channels such that at any given time, whoever is POTUS, around 10% of the US population are convinced that they’re a baby-eating lizard-alien in a fleshsuit who is plotting to bring about the downfall of civilization, rather than a middle-aged male politician in a business suit.

Well now, here’s the thing: automating sarcasm detection is easy. It’s so easy they teach it in first year computer science courses; it’s an obvious application of AI. (You just get your Turing-test-passing AI that understands all the shared assumptions and social conventions that human-human conversation rely on to identify those statements that explicitly contradict beliefs that the conversationalist implicitly holds. So if I say “it’s easy to earn a living as a novelist” and the AI knows that most novelists don’t believe this and that I am a member of the set of all novelists, the AI can infer that I am being sarcastic. Or I’m an outlier. Or I’m trying to impress a date. Or I’m secretly plotting to assassinate the POTUS.)

Of course, we in the real world know that shaved apes like us never saw a system we didn’t want to game. So in the event that sarcasm detectors ever get a false positive rate of less than 99% (or a false negative rate of less than 1%) I predict that everybody will start deploying sarcasm as a standard conversational gambit on the internet.

Wait … I thought everyone already did?

Trolling the secret service will become a competitive sport, the goal being to not receive a visit from the SS in response to your totally serious threat to kill the resident of 1600 Pennsylvania Avenue. Al Qaida terrrrst training camps will hold tutorials on metonymy, aggressive irony, cynical detachment, and sarcasm as a camouflage tactic for suicide bombers. Post-modernist pranks will draw down the full might of law enforcement by mistake, while actual death threats go encoded as LOLCat macros. Any attempt to algorithmically detect sarcasm will fail because sarcasm is self-referential and the awareness that a sarcasm detector may be in use will change the intent behind the message.

As the very first commenter points out, a problem with this is that a substantial proportion of software developers (as indicated by their position on the Asperger/Autism spectrum) find it very difficult to detect sarcasm in real life…

QotD: Futurologists

Filed under: Media, Quotations, Science, Technology — Tags: , , , , — Nicholas @ 00:01

Futurologists are almost always wrong. Indeed, Clive James invented a word – “Hermie” – to denote an inaccurate prediction by a futurologist. This was an ironic tribute to the cold war strategist and, in later life, pop futurologist Herman Kahn. It was slightly unfair, because Kahn made so many fairly obvious predictions – mobile phones and the like – that it was inevitable quite a few would be right.

Even poppier was Alvin Toffler, with his 1970 book Future Shock, which suggested that the pace of technological change would cause psychological breakdown and social paralysis, not an obvious feature of the Facebook generation. Most inaccurate of all was Paul R Ehrlich who, in The Population Bomb, predicted that hundreds of millions would die of starvation in the 1970s. Hunger, in fact, has since declined quite rapidly.

Perhaps the most significant inaccuracy concerned artificial intelligence (AI). In 1956 the polymath Herbert Simon predicted that “machines will be capable, within 20 years, of doing any work a man can do” and in 1967 the cognitive scientist Marvin Minsky announced that “within a generation … the problem of creating ‘artificial intelligence’ will substantially be solved”. Yet, in spite of all the hype and the dizzying increases in the power and speed of computers, we are nowhere near creating a thinking machine.

Bryan Appleyard, “Why futurologists are always wrong – and why we should be sceptical of techno-utopians: From predicting AI within 20 years to mass-starvation in the 1970s, those who foretell the future often come close to doomsday preachers”, New Statesman, 2014-04-10.

For you, is no Singularity

Filed under: Science, Technology — Tags: , , , , — Nicholas @ 11:25

Charles Stross linked to this article which points out that we’re not likely to experience the Singularity/Rapture of the Nerds/etc., and for good reasons:

Given that you are tech-savvy, by that point you have almost certainly come across the idea of the Singularity [1] as defended by futurists like Ray Kurzweil and Vernor Vinge. As a reminder, it is the notion that, when we are at last able to compile a smarter-than-human artificial intelligence, this AI will in turn manage to improve its own design, and so on, resulting in an out-of control loop of “intelligence explosion” [2] with unpredictable technological consequences. (singularists go on to predict that after this happens we will merge with machines, live forever, upload our minds into computers, etc).

What’s more, this seemingly far-future revolution would happen within just a few decades (2040 is often mentioned), due to the “exponential” rate of progress of science. That this deadline would arrive just in time to save the proponents of the Singularity from old age is just a weird coincidence that ought to be ignored.

Objection, your honor. As a scientist, I find the claim that scientific progress is exponential to be extremely dubious. If I look at my own field, or at any field that I am vaguely familiar with, I observe roughly linear progress — a rate that has typically been going on since as far back as the field’s foundation. “Exponential progress” claims are usually supported by the most bogus metrics, such as the number of US patents filled per year [3] (essentially a fashion utterly decorrelated from scientific progress).

And as somebody who does AI research, I find the notion of “intelligence explosion” to make exactly zero sense, for reasons reaching back to the very definition of intelligence. But I am not going to argue about that right now, as isn’t even necessary to invalidate the notion of the Singularity.
