摘要
结合数字图书馆注册用户的特征信息和网络需求行为,提出一种满足用户弱信息需求的用户模型,该模型充分考虑用户的各项指标信息,以用户三级需求模型对各项指标进行量化计算,形成用户需求主题库,进而扩展满足其弱信息需求的主题词。实验表明,该模型可以在一定程度上满足用户弱信息需求。
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 consid- eration 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.
