高三阅读理解The English-language version of Wikipedia has

The English-language version of Wikipedia has almost six million articles. And if you’re a cheating student, that’s six million essays already written for you. But plagiarism(剽窃)isn’t really an effective way-just type the text into a search engine and the game is over. Then what about having a ghostwriter compose your final essay?

“Standard plagiarism software cannot detect this kind of cheating.” said Stephan Lorenzen, a data analyst at the University of Copenhagen. In Denmark, where he’s based, ghostwriting is a growing problem at high schools. So Lorenzen and his colleagues created a program called Ghostwriter that can detect the cheats. 

At its central part is a neural(神经的)network trained and tested on 130,000 real essays from 10,000 Danish students. After reading through tens of thousands of essays labeled as being written by the same author or not, the machine taught itself to tune into the characteristics that might tip off cheating. For example, did a student’s essays share the same styles of punctuation? The same spelling mistakes? 

By examining inconsistencies like those, Ghostwriter was able to seek out a cheated essay nearly 90 percent of the time. The team presented the results at the European Meeting on Artificial Neural Networks, Computational Intelligence and Machine Learning. There’s one more aspect here that could help students. Your high school essays probably get better over time as you learn to write-and the machine can detect that. The final idea is to detect students who are at risk because their development in writing style isn’t as you’d expect. Teachers could thus give extra help to kids who really need it, while sniffing out the cheaters too.
