Towards Serendipity for Content–Based Recommender Systems

Nur Izyan Yasmin Saat, Shahrul Azman Mohd Noah, Masnizah Mohd
2018 International Journal on Advanced Science, Engineering and Information Technology  
Recommender systems are intelligent applications build to predict the rating or preference that a user would give to an item.  ...  However, it is difficult to define serendipity because in recommender system, there is no consensus definition for this term. Most of researchers define serendipity based on their research purposes.  ...  • Serendipity-oriented modification -enhance the systems by modifying the accuracy-oriented system and adapt it for a serendipity purpose.  ...

Generating Self-Serendipity Preference in Recommender Systems for Addressing Cold Start Problems [article]

Yuanbo Xu, Yongjian Yang, En Wang
2022 arXiv   pre-print
In this paper, we devise a novel serendipity-oriented recommender system (Generative Self-Serendipity Recommender System, GS^2-RS) that generates users' self-serendipity preferences to enhance the recommendation  ...  Classical accuracy-oriented Recommender Systems (RSs) typically face the cold-start problem and the filter-bubble problem when users suffer the familiar, repeated, and even predictable recommendations,  ...  for the Filter-Bubble problem Personalized Recommendation is an important factor in recommender systems because a boring, homogenous recommendation is not expected for each individual.  ...

About Performance Evaluation of the Movie Recommendation Systems

Shreya Agrawal, Pooja Jain
2017 International Journal of Computer Applications  
For more and more usage of any system, it is necessary to know about the efficiency of the system and for this reason performance evaluation of a Recommendation system is done.  ...  Movie recommendation systems are now becoming very popular both commercially and also in the research community, where many approaches have been proposed for providing recommendations.  ...  Serendipity In content-based filtering recommendation system there is no serendipitous items, that is, serendipity is the capability of the system to give a product which appear surprisingly interesting  ...
