TRIPLE Deliverable: D5.2 Report on the Recommender System

This deliverable describes the Recommender System in GoTriple. It gives an overview of the background and of the work done so far in Task 5.2.

The document is structured as follows: after a brief introduction into the topic that is given in Section 1, a summary of how the Recommender System service is applied in GoTriple and what benefits it provides to the user can be found in Section 2. Section 3 gives an overview of ScaR – Scalable Recommendation-as-a-service and its software architecture. ScaR is a novel recommender framework following the Software-as-a-Service paradigm. It forms the foundation of the GoTriple recommendation system. How ScaR is used and integrated in GoTriple is presented in Section 4. This includes a fairly detailed description of REST-API services as well as recommendation algorithms and configurations (i.e., profiles) that have been implemented so far.

Section 5 outlines the current state of the work done in TRIPLE. As this is only the first stage of the Recommender System development in GoTriple, we give an overview of planned future work and focus directions in Section 6.
