Special Issue Information

Dear Colleagues,

Nowadays, recommender systems are indispensable in most personalized systems implementing information access and content delivery, supporting a great variety of user activities. Recommender systems alleviate the problem of information overload, identifying and promoting content that is deemed more suitable for each individual user. To this end, recommender systems collect and process information regarding user preferences, likings, and previous actions; the user’s current context (such as the user’s location or company, the time of day or week, etc.); the user’s neighborhood and activity in social networks (friends, posts, message exchanges, and so forth); the characteristics of items to be recommended, including semantic information; and so on. Both static and dynamic views of the collected data are considered, and the algorithms employed to process the available data range from collaborative filtering and statistical models to knowledge-based approaches and matrix factorization.

This Special Issue on “2nd Edition of Modern Recommender Systems: Approaches, Challenges and Applications” aims to promote new theoretical models, approaches, algorithms, and applications related to the area of recommender systems. Authors should submit papers describing significant, original, and unpublished work. Possible topics include, but are not limited to, the following:

  • Models and algorithms to improve recommendation quality.
  • Recommendation algorithms that exploit contextual information, social network information, and/or rich item descriptions.
  • Techniques and methods for enhancing recommender system performance in the context of big data.
  • Privacy-preserving techniques for recommender systems.
  • Novel recommender system applications.
  • Case studies of real-world implementations.
  • Algorithm scalability, performance, and implementations.
  • Cross-disciplinary approaches involving recommender systems.
  • AI-based and explainable recommendations.

Recommender systems on digital platforms profoundly influence user behavior through content dissemination, and their diffusion process is similar to the spreading mechanism of infectious diseases to some extent. In this paper, we use a network-based susceptibility-infection (SI) model to model the propagation dynamics of recommended content, and systematically compare the differences in propagation efficiency among three recommendation strategies based on popularity, collaborative filtering, and content. We constructed scale-free user networks based on real-world clickstream data and dynamically adapted the SI model to reflect the realistic scenario of user engagement decay over time. To enhance the understanding of the recommendation process, we further simulate the visualization changes of the propagation process to show how the content spreads among users. The experimental results show that collaborative filtering performs superior in the initial dissemination, but its dissemination effect decays rapidly over time and is weaker than the other two methods. This study provides new ideas for modeling and understanding recommender systems from an epidemiological perspective. Full article
