Social Network Collaborative Filtering [2007]
Uses Social network as similar user set for Collaborative Filtering
Only use people from Social network as recommenders
Used Amazon.com data about purchases and users’ friends
Drawbacks: For very specific areas of interest, only using social network users might not be very good
Ex: Buying a book about Ontologies
We can try to give more weight to users who are in Social Network but use large number of user for CF
