基于層次分類的頁面排序算法
發(fā)布時間:2019-07-28 18:11
【摘要】:提出了一個基于層次分類的搜索引擎頁面排序算法。該算法通過對頁面進行層次化分類進而計算頁面之間相關性,根據(jù)相關性的不同,對來自不同頁面的外部鏈接賦予不同的權重,從而更公正、有效地計算頁面的PageRank值。層次分類體系更合理地反映了頁面的自然屬性,也為設計更為高效的頁面分類算法提供了方便。該算法與PageRank在在線計算復雜度方面完全一樣,是非查詢關鍵詞相關的算法,能夠高效地完成在線搜索,具有良好的可伸縮性。
[Abstract]:A search engine page sorting algorithm based on hierarchical classification is proposed. The algorithm calculates the correlation between pages by hierarchical classification of pages, and gives different weights to external links from different pages according to the different correlation, so as to calculate the PageRank value of pages more fairly and effectively. The hierarchical classification system reflects the natural attributes of the page more reasonably, and also provides convenience for the design of a more efficient page classification algorithm. This algorithm is exactly the same as PageRank in terms of online computational complexity. The non-query keyword related algorithm can efficiently complete online search and has good scalability.
