| Abstract: | Taking account of the registered information and the network requirement behavior of digital library registered users, a kind of user requirement model is proposed to satisfy the weak information requirement of personalized service. This profile takes full consideration of all the information provided by registered users, builds three levels’ requirement model to quantify the information. Through it, the content of personalized service in the theme database of user requirement can be pushed to users which can expand the terms for weak information requirement. The experiment proves that this model can meet the need of users’ weak information requirement to a certain extend. |
