基于元搜索引擎跨库检索中检索协议标准比较研究

基于元搜索引擎的跨库检索可以检索到通用搜索引擎检索不到的网络数据库资源,但必须解决元搜索引擎与数据库独立搜索引擎间通信的协议标准问题。本文对目前这方面主要的三种通信协议标准OpenSearch,SRU和MXG进行了比较研究,以便为基于元搜索引擎跨库检索研究的发展提供一些有益的参考。

Cross - database search that is metasearch engine - based can retrieve some network database resources that can＇t be retrieved by common search engines, and the protocol standards between metasearch engines and common search engines. This paper analyzes and compares 3 kinds of such protocols： Open Search, SRU and MXG so as to provide some reference for peer research.
