Recommender systems can eliminate users’ information overload and help users make proper decisions by suggesting items based on users’ preferences. However, most current recommender systems overemphasize accuracy. That might cause an overspecialization problem and even lose users’ interest. To overcome the problem, the recommender system can suggest serendipitous items. Exploratory behavior is a facilitator of serendipity. Curiosity, a personality trait, is the most considered characteristics for people’s explorative behaviors and serendipity recommender system. Other than personality, mood is also affected by emotion and influences people’s decision-making. Emotion changes over time, which can be regarded as a relevant factor to short-term user preference and influence users’ thoughts and behavior toward serendipitous information. However, previous serendipity recommender system rarely takes users’ emotion into account. In this research, we proposed serendipity recommendation with different serendipity level to discuss whether emotion matter for the serendipity recommender system and know the relationship between emotion and users’ serendipity preference toward serendipity recommendation list. The result shows that users’ emotion has significant influence on their serendipity preference. Therefore, we believe that incorporating user’s emotion into future serendipity recommendations would improve users’ satisfaction.參考文獻 Abbas, F., & Niu, X. (2019).
