Statistical analyzer that takes a sample of your (or anyone’s) writing and claims to match it based on similarity to a known author: I Write Like.
I pasted an excerpt from an email I had written a while back, and I got the result “I write like Cory Doctorow”. Really? My emails read like Doctorow? This sounded too good to be true, so I dug up my recipe for mushroom-peanut lasagna and pasted that in, and I got the result “I write like Mario Puzo”!
As its name indicates, snarXiv is a parody of arXiv. You can test your bogus-title detection skills at snarXiv vs arXiv. I didn’t get over 60-65% myself (after some 15-20 trials); I could detect the really blatant fakes (“Towards some general examples”), but really my performance is only modestly better than a coin-flip. In my own defense, I’m not a physicist, leave alone a high-energy theoretical physicist. How did you do?
