基于补偿的Nutch搜索引擎的设计与实现

Resign and Implementation on Compensation Algorithm of Search Engine Based on Nutch

Nutch的排序机制使得一些传统的高质量的页面经常出现Web检索结果的前面,而新加入的高质量的Web页面很难被用户找到。针对传统基于链接算法中对新内容的迟钝性,提出了对网页的补偿算法,对Web上在一段时间内好的资源信息使其排名结果上升,而对于不好的资源使其下降,以此来加速优质内容的传播和网络内容的合理化。并最终把改进后的算法应用在基于Nutch的搜索引擎中,通过实验来验证和测试。

Nutch sorting mechanism leading to some of the traditional high-quality Web pages are difficultly to found than the newly added high-quality Web pages. Because of the traditional link algorithm＇ s slow nature to the new content. The compensation algorithm was made for Web page. Period of time to enhance the good information, and the poor information to bring it down, in order to accelerate the spread of high-quality content.
