摘要
随着搜索引擎的快速发展,个性化搜索、社会化搜索已经成为搜索引擎发展的主要发展方向。本文针对用户搜索经验的再利用问题,探索个性化搜索算法。在简要介绍前期工作基础上,重点讨论了用户建模技术、检索案例以及案例排名等问题,提出了一种基于CBR的个性化推荐算法,并在ExpertRec推荐系统进行实验,结果表明,该算法推荐效果良好。
The limited personalized services in current mainstream search engines often make users re-browse some web pages and even fail to find what they need.In this paper,a personalized recommendation algorithm based on CBR for reusing users' search experiences is proposed.Through discussing the modeling user profile,searching and ranking cases in detail,a personalized recommendation algorithm based on CBR(case-based reasoning) is proposed based on users' search experience.The proposed algorithm is applied in the web search recommendation system ExpertRec and good result are obtained.
