摘要: 排名在信息检索领域是一项非常重要的研究课题。然而目前研究页面排名的算法都仅关注页面自身的内容,而并未考虑页面之间的关联性,但这种页面间的关联是普遍存在的。提出了一种新颖的基于页面内容与关联性的排名算法,这种方法既考虑了页面自身的结构特征,又考虑了页面之间的关联性。算法的提出成功地解决了信息检索领域中的“主题蒸馏”问题。为了验证算法的有效性,还在标准的信息检索数据集上进行了对比实验,实验表明算法性能优于传统的排名算法。

Abstract: Ranking is a very important topic in information retrieval.However,existing ranking methods do not use the correlation between objects,but the correlation is prevalent.This paper proposes a new method of ranking based on the use of this correlation.This method takes into account the individual characteristics of objects,but also considers the relationship between objects.This method has dealed with the problem of “Topic Distillation”.Experiments show that this method can effectively enhance the ranking satisfaction.
