The paper represents a kind of user model truss of digital library's personalized service, detailed discusses some key question including express means of user interest model, build of user interest model and renewal arithmetic, lastly based on the personalized text filtrate arithmetic, get the actual validate result of the digital library. The paper represents the express method of vector user model; adopts SVM (support vector machine) and UC (unsupervised clustering) arithmetic combining to pick-up the user interest; adopts LRU (least recently used) arithmetic to realize the renewal of the user interest. The experiment indicated that this model has these characteristic such as adopting implicit mode to acquire user interest and high hit ratio of user mode renewal.
