When I was in grad school, I joined a startup incubator and build a prototype which combined two of the tools mentioned in the article: "a query builder (by demonstration)" and "A paper recommender system", a simple companion which would help scientist to not miss relevant research to them. This was 10 years ago, before Google Scholar has similar features.

The incubator introduced me to advisors with business experience in this field. And I got told in no uncertain terms what is the gist of this article: The value lies in the molecular and clinical data. In 2021 I would add digital pathology / imaging data.
