Serendipity Identification Using Distance-Based Approach

Widhi Hartanto, Noor Akhmad Setiawan, Teguh Bharata Adji
2021 IJITEE (International Journal of Information Technology and Electrical Engineering)  
Consumers expect recommendations that are novel, unexpected, and relevant. It requires the development of a serendipity recommendation system that matches the serendipity data character.  ...  The recommendation system is a method for helping consumers to find products that fit their preferences. However, recommendations that are merely based on user preference are no longer satisfactory.  ...  A recommendation system dealing with this serendipity criteria is known as a serendipity recommendation system.  ...

Burst the Filter Bubble: Using Semantic Web to Enable Serendipity [chapter]

Valentina Maccatrozzo
2012 Lecture Notes in Computer Science  
To break this "personalization bubble" we introduce the notion of serendipity as a performance measure for recommendation algorithms.  ...  The use case for this work focuses on TV recommender systems, however the ultimate goal is to explore the transferability of this method to different domains.  ...  As described above, serendipity in the context of recommender systems is represented by a well balanced mix of diversity, novelty and relevance of the recommended items with respect to the users' interests  ...

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  
Having a serendipitous recommendation let users explore new items that they least expect. This has resulted in the issues of serendipity in recommender systems.  ...  Thus, in this paper, we aim to formally define the concept of serendipity in recommender systems based on the literature work done.  ...  Both systems might be improved if they have a specific definition of serendipity in recommender system.  ...
