Abstract
Recent recommender systems studies have started focusing on accelerating serendipity to offer users diverse perspectives. However, recommending serendipitous items is known to decrease users' satisfaction due to low recommendation accuracy. In this paper, we propose a probabilistic serendipitous recommendations (PSR) model that aims to discover serendipitous items through the fully-connected combinations of unrelated user-provided information. The proposed model provides an unexpected result, while user's answers are maintained not to decrease recommendation accuracy. An online user study with 40 participants revealed that the proposed PSR model provides serendipitous items by using the intersection of usefulness and unexpectedness from the recommended results.
