I interviewed with a company that built a Electronic Medical Records system optimized for cancer treatment, licensed it for cheap, then took the data and paid for medical professionals to spend time normalizing the free-text notes data from the doctors (this was ~a decade ago, when LLM's were not really a thing, so they got trained professionals to do it instead). That was all a play to get the level of data they wanted for training AI to make new discoveries. They got acquired by a major pharmaceutical company, but I don't know of any major discoveries made from their data. Because even with real data this is a hard problem.
