Collaborative filtering + vote weights.

Answer 2

Book - Grokaem Algorithms (Aditya Bhargava)
The chapter "K Nearest Neighbors Algorithm" has some interesting ideas, using Netflix's simplified movie recommendation system as an example.
Although, in my opinion, it’s just enough for you to collect the number of likes and everyone who has more is cooler. After all, you are not going to recommend it specifically to Ivan or Petya, but to everyone in a row, without having data on their personal preferences, that is, to an anonymous person, I think there will be bare numbers, there is nothing to compare with.
In addition, you can google, better in English "how to build a rating system algorithm":

2) algorithm used to calculate 5 star ratings
