摘要
倒排文件是搜索引擎检索系统普遍采用的索引技术。在实验基础上,针对中文搜索引擎中索引的时效性和传统倒排索引在更新时的缺点,提出分组索引技术和一种追加索引的更新算法,可以有效提高搜索引擎的检索效率,同时不影响系统检索效果。
The full -text inverted index based on automatic Chinese segmentation is a popular technology for Chinese search engines, in this paper, we propose a grouping inverted index method and an updating arithmetic by using the superadding index. The experiment shows that this two methods can improve the retrieval efficiency and have no negative influence on system＇s effectiveness.
