Personalized Recommendation Algorithm Based on Task Features and Witkey Behaviors

With the rapid development of witkey websites, the amount of witkeys and tasks on the witkey sites as well as has risen sharply, how to accomplish witkeys and tasks rapid matching becomes a critical issue faced by most witkey websites. To resolve this problem, this paper analyzes the online tasks and the witkey behaviors on the websites in detail and addresses the concept of preference order. Then, the online tasks model and the witkey preferences model are constructed based on vector space. Finally, the online tasks are recommended to the witkeys according to the similarity between the online task vector and the witkey preferences vector.
