Thanks for the reference. I have checked the discussions about Tag Feature for moodle but it has not been implemented fully so far.
So I would like propose this idea for GSoc'13 : "Automatic Tag Suggestion & Retrieval".
The key idea is to implemet fully functional Question tagging feature which will allow user to retrieve questions belonging to same categories and even also recommends them from the predefined datasets.
Any inputs?
