PHP simulation algorithm design

1. Add different labels to the data. For example: attractions [hot, top, sellest], the same is true for hotels.

2. Design an itinerary based on user behavior preferences. [Refer to the travel tips].

The above are roughly the requirements of the application, but when implementing it, because I am unfamiliar with the algorithm, I use labeling to design a solution for users. However, the amount of data is large and complex, and there are many problems in implementation, such as pressure on the server. , query calculation efficiency and speed, I would like to ask everyone if you have a mature idea to implement it.
