A mathematician is just getting into applied category theory. She queries for active programs to decide what she wants to pursue, then queries for people who will mentor her in the field. She finds someone who will for one hour per month, which is enough to get started.

Someone with a community development role in ACT wants to see what the emerging subfields are, and how promising they are. They query for recently published papers, sort them by subfield, and order the subfields by the amount of people in the database who express an interest in that subfield or objects related to that subfield.
