An overlapping clustering approach for precision, diversity and novelty-aware recommendations
作者:
Highlights:
• Scalability is improved using an overlapped clustering.
• Clusters of diverse and similar members are identified using a genetic algorithm.
• Recommendation relevance and diversity trade-off is controlled using a new encoding.
• Our approach improves accuracy, coverage, and novelty of recommendations.
• Experimentations on real-world datasets.
