It is a necessary and urgent task to realize the archives intelligent service based on collaborative filtering. In this paper,based on collaborative filtering,an archives intelligent service implementation model is proposed for alleviating users’pain-point problem. This model implements the study-purpose intelligent service by using expert opinions collaborative filtering,implements the affair-purpose archives intelligent service by “virtual user-affair type”matrix space calculations,and implements the diverse-name retrieval intelligent service by“archives resource-retrieval keywords”matrix space calculations. In practical application,these conceptual design models can be instantiated according to the service scene to realize archives intelligent service.
