摘要 随着Web信息量的不断增多,人们不得不花费大量时间去搜索、浏览和选择自己需要的信息,改善和提升搜索引擎信息检索的能力已经越来越迫切。提出基于专家用户搜索历史的信息推荐模型,并重点介绍普通用户和专家用户Profile以及基于此的2个计算模型。在此基础上结合Nutch搜索引擎平台,开发面向语义搜索的推荐系统,实际使用证明推荐效果良好。 The overload of information makes it too time consuming for common users to find what they really want. It is very urgent to improve current search engines. This paper,presents a recommendation model based on experts' search histories for recommending Web Pages. Two kinds of user profiles are defined:common user profile and expert profile. And two computation models are given. Based on the oboved methods a semantic search recommender system running on Nutch Search Engine. It is validated that performance of recommendation is favorable in practice.
