Recommender System on Rapidminer
Contributor II
Hi
I'm trying to build a recommendation system to recommend goals for users based on their goal list..
it's my senior project I'm working on it by my own, and running out of time,
so pleeeeease I need any avilable help or advice you can provide me with ;
I have my dataset (125 user ,7 category,1800 goal name) as access database
I have made the cluster for each goal category separately, got 5 clusters group for each category
I made a lot of manual work, I renamed clusters name, made crosstab query for clusters name with user ID,did other modification to get binominal values as showen in here (f=means they don't have goal in the cluster,t=mean they do)
then in an other process I apply the association rule for frequent items as in here:
I know how terrible this is, I even didn't get final certain recommended goal!!
my interface will be as webpage
how can I fix my process ??
How can i do the association analysis directly with the output of the clustering operator? Without the need of all my manual work?
I have every category having its own process how can i group them together?
how should the process be when new user enter new goal
What it should go through?!
is there a better way to build my system?!
any help will be very much appreciated
regards
