发布时间:2019-02-26 21:13
【摘要】:介绍Google等搜索引擎应用的PageRank算法的定义、特点及缺陷。针对PageRank算法在基于Ontology的海洋文档检索系统应用中的问题对其加以改进,增加了文本文档的判断和主题相关性的判断,提出IPageRank算法。介绍海洋文档检索系统,并将改进的IPageRank算法应用于该系统中进行验证。
[Abstract]:This paper introduces the definition, characteristics and defects of PageRank algorithm used by Google and other search engines. In order to improve the PageRank algorithm in the application of Ontology-based marine document retrieval system, the text document judgment and subject correlation judgment are added, and a IPageRank algorithm is proposed. The marine document retrieval system is introduced, and the improved IPageRank algorithm is applied to verify the system.
