作者:

Highlights:

• A social recommender system method called TCFACO is proposed.

• Trust statements are used as a side information to deal with the data sparsity and cold-start issues.

• TCFACO uses available rating values along with social trust relationships to rank users.

• TCFACO uses ACO to choose a set of valuable users with their associated weights.

• Final selected users are used in the rating prediction considering their similarities to the target user.
