摘要 兴趣模型是个性化信息服务的关键技术,介绍了基于用户反馈的兴趣模型的构造过程,并将其应用于信息检索中,通过利用反馈对检索结果集重新排序、利用反馈形成新的查询请求两种方式优化检索结果,使其能更好地符合用户的个性化需求,并说明了利用反馈对兴趣模型进行调整的原则。 User's interest model is the key technology of personal information service, the construction process of the interest model based on user's feedback is introduced, and the model is applied on information retrieval. The result set of retrieval is resorted or retrieved by feedback, and regulative principle of interest model is introduced.
