A computer that can detect sarcasm

Straight from Neatorama:

A research team at Hebrew University in Israel has developed a computer program that can recognize sarcasm with about 77% accuracy:

To create such an algorithm, the team scanned 66,000 Amazon.com product reviews, with three different human annotators tagging sentences for sarcasm. The team then identified certain sarcastic patterns that emerged in the reviews and created a classification algorithm that puts each statement into a sarcastic class.

The algorithms were then trained on that seed set of 80 sentences from the collection of reviews. These annotated sentences helped the algorithm learn what sorts of words and patterns distinguish sarcastic remarks - those that mean the opposite of what they literally convey, or that convey a sentiment inconsistent with the literal reading.

Wow that's so totally interesting and amazing!

(I'll bet my comment easily falls into the 33% of sarcasm that the computer doesn't detect)

So, the methodology involved humans first identifying sarcastic comments. The 77% accuracy is probably just how closely the computer matched what humans found to be sarcastic. Anecdotal evidence has taught me that less then 20% of humans seem able to detect sarcasm, so the computer only would detect about 15% of all sarcasm.

Interesting, amazing, and at least as accurate as anti ballistic missile defense systems! I foresee huge government contracts for this technology with immediate deployment in the Senate chambers.

Oh, a sarcasm detector. That's really useful!

77% accuracy makes that program better at detecting sarcasm than the average Internet reader.

That really is interesting and amazing.

Better yet, they'll have Don Rickles to try it out on. (However, they should be cautious; this could lead to the overload Katherine warned about.)

Next we'll have an application that generates sarcasm. Imagine the possibilities! Nobody's job is safe anymore. (I'm looking at you, Jon Stewart.)

"77% accuracy makes that program better at detecting sarcasm than the average Internet reader."

haha, great remark, i've just thought the same after reading this post ;)

Now we can not wait, but health reform should be established in a way that the beneficiaries are those who suffer everyday with different diseases such as cancer, Parkinson's, arthritis, diseases that are painful and have to suffer day after day, for them must be a priority.

100 - 77 = 23 (%)

@Ken: "Anecdotal evidence has taught me that less then 20% of humans seem able to detect sarcasm, so the computer only would detect about 15% of all sarcasm."

Even if only 20% of humans detected sarcasm, that would not translate to only 20% of sarcasm being detected, thus your considering the 77% of 20% sarcasm is wrong.
