摘　　要：由于PageRank算法在计算过程中没有考虑垃圾页面对网页排序结果的影响,论文对PageRank算法进行了改进,使其在计算过程中为垃圾页面及其链接页面传递较低的Pr值。实验表明,改进后的算法明显降低了垃圾页面对网页排序结果的影响,提高了页面间的相关度和区分度。Because PageRank algorithm has not considered the effect of Web Spare in its calculation process, an imporved PageRank algorithm is described which takes the spam pages into consideration for the calculation of PageRank. The experiment shows that the improved algorithm has obviously reduced the effect of Web spam on the results of sorting, the degree of relevance and difference is increased.
