Network-Based Extension of Multi-Relational Factorization Models

Complex heterogeneous networks contain many types of relations, both local to a particular entity and distant in the network. Multi-relational factorization schemes that incorporate multiple local relations have shown improved recommendation accuracy. This paper extends this prior work on multi-relational factorization to include extended relations derived from network data and demonstrates improved accuracy for these extended hybrids.
