What is the principle of linking products to categories for aggregators?

Question

Yandex Market

started writing an aggregator in yii2, stopped at linking categories, can someone tell me how to link source categories with aggregator categories? You can, as an option, manually bind for each aggregator, but this is a long time. How to automate these moments?

Answer 1

Fuzzy comparison of chains of categories and product names.

Answer 2

if you want it to be safe, do it manually. Well, either pre-prepare matches by name, but then check anyway.

Answer 3

And what does yii have to do with it? There can be many algorithms, but they are not even particularly dependent on the PL.
In addition to what they wrote to you, you can try machine learning. I agree that it is not the easiest and fastest option, but then you can sell such a solution.
