Php simulation algorithm design

Add different labels to data. For example, scenic spots such as hot, top, and sellest are also the same. Design the itinerary based on user behavior preferences. [Refer to mxtrip ]. The above is roughly the application requirement, but in implementation, due to the unfamiliar algorithm, we use the label-based method for the user designer...

1. Add different labels to data. For example, scenic spots such as hot, top, and sellest are also the same.

2. Design the itinerary based on user behavior preferences. [Refer to mxtrip ].

The above are roughly application requirements, but in implementation, due to the unfamiliar algorithm, we use the label-based method to design solutions for users, but the data volume is large and redundant, there are many problems in implementation, such as the pressure on the server, the efficiency and speed of query computing. I would like to ask you to come up with a mature idea for implementation.
