摘要
在分析个性化搜索引擎的基础上,提出一种构建用户兴趣模型的方法.该方法综合考虑用户注册兴趣及浏览行为,将用户兴趣分为长期兴趣和短期兴趣并通过兴趣树进行存储.遗忘机制的引入保证模型能够及时准确地反映用户兴趣.模拟实验表明,本文提出的用户兴趣模型能够有效地提高检索效率,使搜索结果更好地满足用户个性化需求.
This paper presents a way to construct user interest model in personalized search engine. The user interest model takes the registrated interest and user browse behavior into consideration. It consists of long-term and short-term which is stored in user interest tree. Forgetting mechanism is provided to timely refresh user interest. Simulated experiments verify the user interest model proposed in this paper is effective and competitive.
