An Effective Recommender Algorithm for Cold-Start Problem in Academic Social Networks

Algorithm 1

The ECSN selection process.

for each u  ∈  U

{

  (1) Generating the ordered stack of item categories (ItemStack) based on PS value computed by Definitions 2 and 3.

  (2) SIC ← 0  // Initializing the Selected Items Count (SIC) by 0

  (3) SC ← 0 // Initializing the selected category (SC) by 0

  (4) While  (SelectedItems < 10)

  (5)   {

  (6) TopItemCat←POP (ItemStack),

  (7) TopItemsList←FindNewItems(TopItemCat, PrioritizedCount(SC))

  (8) SIC −= count(TopItemsList)

  (9) Adding  TopItemsList  to  RecommendationList

  (10) }
