The data was collected for a paper that was attempting to find a lexical difference between human contributions and LLM contributions. The reason for this was because repository maintainers need to make sure submitted code has been at least reviewed by a human. By detecting unattributed AI submissions, it can tell maintainers that they need to pay extra attention to the repositories.

And does that work? Can you genuinely tell whether a human has reviewed Ai-assisted/generated code?
