What technology will allow grouping data with training?

Question

Neural networks

Good afternoon!
Task: there is tabular data with table parameters (title, subtitle). It is necessary to group data based on the table parameters and values ​​from a pair of columns. The values ​​from the columns are id and relatively arbitrary text. There is no sample for training, the system will have to be trained by the user during operation, i.e. the system offers its own options for grouping, and the user corrects it.
I am not familiar with neural networks and training, so I ask for advice in which direction to start digging?
