Research problem leaderboard call
There is a requirement to create a leaderboard of authors and contributors to a problem. To this end we would need to create a call or two, one to get the authors of all the papers addressing a certain problem, and then rank them on the frequency on which they are involved there.
Another call is needed to get the contributors (ORKG users), we are already doing something similar in the timeline dsiplayed next to the paper view, we can do this also for all papers and then rank them somehow (I guess similarly to the authors i.e. by paper participation frequency)
