基于超链接结构和向量空间模型的网页排序算法研究

在传统的向量空间模型中，TF-IDF算法被广泛应用在基于关键字的信息检索中，而随着对web检索研究的不断深入，充分利用Web文档结构的超链接信息对提高web检索的查全率和查准率有重要作用．因而本文对这两方面算法的结合进行了研究，并对其改进进行了讨论。

The Algorithms of Web Page Ranking Based on Hyperlinks and VSM

In the traditional information retrieval systems based on the vector space model, the TF-IDF scheme is widely used to characterize documents. Along with rapidly research of the web information retrieval, more and more hyperlink contents are sufficiently combined with, and the higher and higher precision and recall are achieved. Some possible improvements on the two algorithms are discussed.
