With the continuous development of Internet technology, the popularity and improvement of people's life, work and learning are increasingly free from the restrictions of time, space, geography, networks have become an indispensable part of people's lives learning. In the field of education, the acceleration of the process of education information has been unstoppable. At the same time, the deepening of the process of education information platform of information technology education, education resource library put forward higher requirements. Currently, the endless stream of various websites about education, these network resources at the same time bring a wealth of knowledge and great convenience to the people, and also exposing some of the problems, the most important is the \needs. In order to solve the problems associated with personalized service began to be more and more people to study and use. Personalized service to users may be interested in the resources based on the user's personality, preferences seriously learn from the technology of personalized service while, I had an idea: simple only passively as the face of the user's personalized service user to provide the service, if not the fundamental solution in the repository, then, want to perfect the repository is impossible, can finally be resolved technically repository is the repository managers. This article is from the start with this question, and personalized resource library update service models for repository managers. Around the repository update service, collect information from users, user interest model, resource model, based on the match between the content and collaborative filtering, model and other aspects of the repository update service model principle and implementation process. In the repository update service model theory building process for the user interest model and resource model, were taken based on the representation of the vector space, based on the Fibonacci forgetting algorithm; For collaborative filtering, data mining poly class of algorithms; model building after matching the Euclidean distance between the calculation model for managers to push the appropriate resources, from the fundamental solution to the resource library resources can not meet user needs. Finally, through simulation, to verify the feasibility of the the repository update service system, provide a strong support and guarantee for the further development and research update service system.
