Abstract EN
Link recommendation is a popular research subject in the field of social network analysis and mining.
Often, the main emphasis is put on the development of new recommendation algorithms, semantic enhancements to existing solutions, design of new similarity measures, and so forth.
However, relatively little scientific attention has been paid to the impact that various data representation models have on the performance of recommendation algorithms.
And by performance we do not mean the time or memory efficiency of algorithms, but the precision and recall of recommender systems.
Our recent findings unanimously show that the choice of network representation model has an important and measurable impact on the quality of recommendations.
In this paper we argue that the computation quality of link recommendation algorithms depends significantly on the social network representation and we advocate the use of actor-fact matrix as the best alternative.
We verify our findings using several state-of-the-art link recommendation algorithms, such as SVD, RSVD, and RRI using both single-relation and multirelation dataset.
