MoPE contains over 100 examples of copy editing errors from English-language news publications. The examples are mostly from publications owned by The New York Times Company (NYT, Wirecutter and The Athletic), primarily because the Internet has developed somewhat of a sport in playing grammar police for them. But also because The Times has high editing standards, so the errors that sneak through are often grammatically interesting. 

GPT-4 has a 54% error rate on the task of identifying the word with an error or the word closest to the error. 

The dataset is maintained by the editors of [Machines on Paper](https://www.machinesonpaper.com/). We would love to add copy errors from other publications. You can send suggestions to hello@machinesonpaper.com.
