Abstract
A content recommendation device is provided, including a selection engine selects content items from a content item pool and generates a selection list including the selected content items, wherein said selection engine selects the content items from a content item pool according to a user profile, and/or a receiving unit configured to receive a selection list selected from a content item pool according to a user profile, and a user profiling engine that a part of at least one previously generated selection. The user feedback includes explicit and implicit feedback so that a very simple explicit feedback, which gets refined by the corresponding implicit feedback, is possible.
