Collaborative Filtering Item Recommendation how can I create output "item_id" with title name
hi
I use Rapidminner for Collaborative Filtering Item Recommendation with user k-nn and the result at "item_id" is number like this
so how can I create or replace number in 'item_id' with title name like this. Or how can I show output with title name in new attribute.
I try to use set role operator and set additional roles : attribute 'title' with 'item identification' but output is the same. the "item_id" still be number.
sorry for my English isn't good.
Thanks you for your help

Hi @tonybunjong,
if your item_id attribute is a polynominal type, you can use the Map Operator to replace the old values for new ones.

Hi @ceaperez
Thank you for the solution.
Now I'm face the same problem but I can't use Map Operator because as I understand Map Operation is replace the value one by one but in my case I have a lot value to reply, Do we have the other way to resolve this problem.
From the screenshot below, I want to show Movie Name (title) instead of item_id.
