Yes. For example, this story about Ukraine [1] is credited to WNYT as first, but the story itself credits the Associated Press.
This problem is worth solving, because it's something search engines should be doing.
yea, what im currently doing is pretty simple check on published at date from the rss feed (with some small validation checks)... but its causing issues bc it can be wrong and mess up everything...
Treating the Associated Press as a special case might be worthwhile. Its stories will appear in hundreds of places, some with a little alteration and some fully intact.
I think checking source in story is next step...
