Deploy ur engine as a popularity or trending feature

Hi all,

I'm deploying the feature popularity and trending for a video website. I have a set of data with userid(123) and itemid(27s92jAv8d). With these 2 fields, I deployed an personalized recommendation but I dont know how to make a query for popularity and trending results. I read here http://actionml.com/docs/ur_advanced_tuning. Can u give me some clues for this. Thanks
