以一个自行开发的搜索引擎系统为背景研究主题提取算法,通过对几种经典主题提取算法的分析、融合,提出了一个新的主题提取算法。用该搜索引擎证明了新提出算法比经典的HITS算法在性能上有很大的提高。
Takes an own designed search engine system as background to study topic distillation algorithm, through analyzing and combining with several classic topic distillation algorithms, proposes a novel topic distillation algorithm. Experiments show that the algorithm is more effective than HITS algorithm.
