Relevance-based language modelling for recommender systems

作者:

Highlights:

• A new recommendation approach based on the Relevance Modelling (RM) of the problem is proposed.

• The neighbour selection problem is improved by Posterior Probabilistic Clustering (PPC).

• Background information such as item popularity is successfully integrated by using RM models.

• Performance of the recommendation improves when more clusters are considered in the PPC technique.

• Combination of both contributions leads to an even better performance than their separate application.
