發(fā)布時(shí)間:2019-02-26 21:13
【摘要】:介紹Google等搜索引擎應(yīng)用的PageRank算法的定義、特點(diǎn)及缺陷。針對(duì)PageRank算法在基于Ontology的海洋文檔檢索系統(tǒng)應(yīng)用中的問題對(duì)其加以改進(jìn),增加了文本文檔的判斷和主題相關(guān)性的判斷,提出IPageRank算法。介紹海洋文檔檢索系統(tǒng),并將改進(jìn)的IPageRank算法應(yīng)用于該系統(tǒng)中進(jìn)行驗(yàn)證。
[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.
