| 摘 要： | 个性化检索是信息检索领域研究的热点。要实现个性化检索必须收集用户兴趣。用户兴趣不能一概而论，针对不同的查询，用户的兴趣应该不同。选取与当前查询相关的检索历史构建查询上下文，通过查询上下文对检索结果进行重新排序。实验证明，个性化检索性能有所提高，提高的因素来自于最临近的几次检索历史，而更长的历史数据会使系统的运行效率下降，同时还会带来嗓音。

| Abstract: | Personalized search is a hot pot in the domain of information retrieval research.In order to personalize search,user interest which changes for different search surroundings should be collected.The authors investigate the impact of history length on the effectiveness of personalized ranking,and use search history related to current query to construct query context,which are used to re-rank results for the current query.Experimental results show that the performance of personalization generally improves as m... |
