摘    要:垂直搜索引擎的主题搜索策略有基于内容评价的搜索策略和基于Web链接分析的搜索策略,其中HITS算法是一种经典的基于Web链接分析的搜索策略,其主要的缺点是容易发生主题漂移。为了最大程度地避免主题漂移,提出了一种结合网页文本分析和扩散速率改进的F.HITS算法。实验结果表明,这些改进不仅节省了系统的开销,并且提高了页面搜索的准确率。

关 键 词:垂直搜索  搜索策略  扩散速率  文本分析  超链接分析主题搜索(HITS)

Abstract:Vertical search engines have two kinds of subject search strategy, one is based on content evaluation, the other is based on Web link analysis, and HITS algorithm is a classical search strategy that is based on Web link analysis. Its significant drawback is easy to engender topic drift. In order to avoid engendering topic drift in the maximal degree, this paper puts forward a modified F-HITS algorithm that combines Web' s text analysis with diffusion rate. Experiment' s results show that those improvements not only can decrease system spending but also raise the accuracy of Web page searching.
Keywords:vertical search  search strategy  diffusion rate  text analysis  Hyperlink-Induced Topic Search(HITS)
