During the last years, as virtual assistants such as Siri (Apple), Google Assistant, Amazon Alexa, spread into everyday situations, conversational recommender systems were proposed as an interactive recommendation process to connect with the user. However, there is little knowledge about the personalization of conversational recommender systems as a way to increase the satisfaction of the users. The current research focuses on the users’ experience with a movie platform. It argues that users satisfaction can only be improved if the conversational recommender system knows the preferences and the Openness to Experience of the users, and therefore gives custom-made recommendations. Specifically, the relationship between the degree of Openness to Experience and serendipitous or accurate recommendations is investigated. The present study demonstrates that overall people low on Openness to Experience significantly prefer accurate suggestions rather than serendipitous ones. Instead, people high on Openness to Experience do not have a significant preference regarding accurate or serendipitous recommendations. Furthermore, to explore whether a conversational recommender system increases user satisfaction, this study explores to what extent the satisfaction of users in recommender system is dependent on (traditional vs. conversational) recommender system mode of interaction. Results indicate that conversational recommender system exerts a positive impact on user satisfaction.
