An explicit trust and distrust clustering based collaborative filtering recommendation approach

作者:

Highlights:

• A SVD signs based trust and distrust clustering method is proposed.

• A trust inference method is proposed to compute indirect trust between users.

• A trust neighbors mining algorithm is proposed to discover trust users.

• A sparse rating complement algorithm is proposed to get dense user rating profiles.

• The TCCF method is efficient in terms of prediction accuracy and coverage.
