Why do we need it? Automatically produced texts use language models derived from statistical analysis of vast corpuses of human-generated text to produce machine-generated texts that can be very hard for a human to distinguish from text produced by another human. These models could help malicious actors in many ways, including generating convincing spam, reviews, and comments — so it’s really important to develop tools that can help us distinguish between human-generated and machine-generated texts. – Boing Boing
