In the evaluation of recommender systems, the quality of recommendations made by a newly proposed algorithm is compared to the state-of-the-art, using a given quality measure and dataset. ...
The experiments aim to quantify the expected degree of variation in performance that cannot be attributed to differences between systems. ...
The difference in performance seems to indicate that care must be taken to take into account some degree of randomness in recommender systems evaluation that involve users in a live setting, in addition ...

The evaluation results show that one of these recommendation methods, the one using general unexpectedness independent of user profiles, can recommend the serendipitous items accurately. ...
Although recommender systems have been improved in terms of accuracy, such systems are still insufficient in terms of novelty and serendipity, giving unsatisfactory results to users. ...
Next, the system recommends ten high-score programs by using the proposed methods, random recommendation, and a method using only unexpectedness for each user from the remaining evaluated programs by using ...
