- Cross-domain recommendations in RecSesame

Source: Recommender Systems Handbook. Francesco Ricci, Lior Rokach, Bracha Shapira.

Short description

Cross-domain recommender systems (CDRS) aim at generating recommendations that span across multiple domains by transferring knowledge from a source to a target domain, with the assumption that there are strong dependencies between items of those domains. For instance one can recommend movies to a user based on the information of the music she listens to. Traditional approaches show limitations when dealing with this problem.

The goal of this project is to integrate a recommender algorithm into RecSesame, a framework developed at out department, which generates cross-domain recommendations. The efficacy of the algorithm can be evaluated by the platform itself by means of an off-line evaluation.

Pre-requisites: knowledge of RDF, recommender systems. Programming in Java, Python; use of Maven.

Recommended number of participants: 2 per group

Status: assigned (2 groups of 2 students each)
