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。This paper introduces the definition, the characteristic and the limitation of PageRank algorithm used by Google and other search engine. It develops a system, ocean search system, which is based on Ontology and PageRank algorithm. However, because of PageRank algorithm＇s insufficiencies in this system, a new algorithm is proposed and applied in the system＇s consummation. It introduces the functions of the ocean search system and takes an illustration and test to the new algorithm.
