A Novel Hybrid Similarity Calculation Model

Algorithm 1

Description of RIT-UA algorithm.

Algorithm RIT-UA similarity calculation

Input:

Testset

Algorithm

For user in Testset do:

For item in Testset[user] do:

//get co-rated items

Users: getCorateditemsUserset(item)

//get the similarity between user and Users

calculateRituaSimilarity(Users, user)

//According similarity select neighbors

getTonKNeighbors(K)

//calculate predicted rating

rating: getRating(Neighbors)
