个性化元搜索引擎中的查询优化

Query Optimization in Personalized Meta-search Engines

为了提高搜索引擎的准确度,以达到对用户查询进行优化,缩小用户查询的范围,使用户得到更准确查询结果的目的,在考虑到用户兴趣的基础上,提出了一种用户查询到用户兴趣类的映射技术.介绍了采用该技术所建用户个性化模型的总体结构和各个模块并进行了实验.结果表明,该技术的应用能实现对用户查询的优化.

In order to enhance the accuracy of search engines, many meta-search engines carry out the mapping from user＇s query to category, which are aimed to optimize the user＇s query, to reduce the scope of user queries, so that users can get more accurate results of queries. Based on the interest＇ of the user, a user＇s query to the user interest in the category mapping technology is introduced in this paper to achieve the optimization of user queries. Results show that the application of the technology can achieve the optimization of user queries.
