搜索引擎的相关排序算法分析与优化

Analysis and Optimization on Search Engines' Relevance Ranking Algorithm

相关排序技术是搜索引擎结果处理的一个核心技术,其排序算法的优劣直接影响查准率.笔者阐述了现有排序算法的优缺点,分析了不同排序算法对查准率的影响,从根集的质量、噪音链接、查询分类几方面进行了优化并考虑了综合因素,提出了一种切实可行的相关排序实现方案.

The relevance ranking technology is a core technology of the search engine result reduction,and the ranking algorithm is directly influence the accuracy ratio.At first,this article points out the good and bad points of the existing ranking algorithm,then it emphatically analyzes the effects of the different ranking algorithm on the accuracy ratio.At last it proposes one kind of advanced ranking algorithm according to these similarities and differences of these methods.
