No, it’s not manually labeled. It connects the text to the image based on things like alt text or the comment next to it in a social media post, and then ran them through a different AI (CLIP) which rated how well the text description matched the image and they filter out the ones with a low score.
The point of the OP research is that they should add another step to check CSAM databases and not rely on social media curation to have avoided illegal material (which they should, even though it’s a very very small portion of the overall dataset).
But at no time was a human reviewing CSAM, labeling it, and including it in the data.
Don’t they need to label the data?
