Collaborative Filtering Item Recommendation how can I create output "item_id" with title name
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
