摘要/Abstract

摘要： 针对现有用户兴趣模型在模型建立以及更新阶段漂移策略的缺陷，设计了一种改进的基于隐式反馈的自适应用户兴趣模型。并将该模型与遗忘策略模型、滑动时间窗口模型和固定比例模型，做了精确率的对比实验，实验结果显示该模型的性能优于其他三个模型。

Abstract: The article proposes an adaptive user model for dealing with limitation of excursion policy when building and updating step in the user interest model which is based on the implicit feedback.After comparing with forgetting strategy model sliding window model and fixed fraction model，experiment’s result show that the capability of this model is better than the other models.

Key words: personalizes recommendation service, user interest model, Vector Space Model
