Discriminate2Rec: Negation-based dynamic discriminative interest-based preference learning for semantics-aware content-based recommendation

作者:

Highlights:

• A three-stage preference learning approach to content-based recommender systems.

• Semantical and temporal attribute-level coherence of user profile are improved.

• User profile is learned based on discriminative user-attribute interest weights.

• The discrimination between items’ attributes improves the recommendation accuracy.

• Introducing a negation-based profile modelling method for accurate recommendation.
