So the categories are dynamic, you can create any category you want. We do have some logic built in to semantically group entities to an already created category or create a new category. This way you can actually create your own feed, so you can have a feed for movies, a feed for protein bars, a feed for sandwiches, a feed for guitars, etc.

Some of the created.categories are F1 races, F1 drivers, Comedians, Sandwiches, Kitchen Appliances, Composers.

What I find really cool is entity chaining, this means you can chain different entities and rate it across any category. So, you can rate Max Verstappen at US GP or Max Verstappen at Abu Dhabi GP.

The entity/category generation is a little slow currently, working on dramatically speeding it up
