In a paper posted to the arXiv preprint server this week, a team of computer scientists from the Renmin University of China in Beijing describes their system for fooling a computer trained to understand language. In short, by adding one very specific word to a particular part of a long sentence, or slightly misspelling one word in a phrase, a computer trained to say whether a sentence is about buildings or corporations will completely flip its analysis.
