Recommending based on rating frequencies – Accurate enough?
Proposed method: RF-Rec
‧ Use a very simple prediction function
‧ Given:
– For each possible rating value r, the number of times the active user U has used it.
– For each possible rating value r, the number of times the target item has received this value from the community
‧ Predict:
– The rating value that appeared most often for this user/item combination
