Recommenders extension: How to convert integer results back into text?

RionArisu

I have attempted to use "Recommenders" extension to build a model which provide recommendation based on collaborative filtering logic. The input data are as such:
User | Item | Score
A | Item X | 5
B | Item Y | 3

However, after the results are generated, it has automatically converted the user and item into ID, e.g.
User_id | Item_id | Rank
0 | 1 | 1
0 | 4 | 2
1 | 3 | 3

It seems like it has automatically change the nominal value into unique integers. May I know how can I convert these unique integers back into nominal results?

Many thanks!

Have you tried Numerical to Polynomial operator?
