摘要
在研究搜索引擎关键技术的基础上,深入细致地剖析了著名搜索引擎Google的链接分析排名算法PageRank算法,解说其运行原理并给出改进算法。在此基础上指出PageRank算法存在的缺陷,从而针对性地提出了优化方案,实验结果表明,改进的算法有利于提高算法的运行效率,提高用户对检索结果的查准率。
The PageRank algorithm of the search engine Google is studied. The running principle of the algorithm is discussed, and an improved algorithm is presented. The deficiency of the PageRank algorithm is pointed out, and an optimized scheme is proposed. The experimental results show that the efficiency of the improved algorithm is enhanced, and the retrieval accuracy is improved.
