摘要
以国外学科信息门户为例,介绍分析了在分布式学科信息门户中实现交叉检索与交叉浏览的相关技术:跨库检索技术、元数据互操作技术、分类法映射技术等。
Based on some of the subject gateways currently accessible through the web, this paper introduces and analyses the key techniques to cross- searching and cross browsing in a distributed infrastructure, such as cross- database searching technique, metadata interoperability and classification mapping.
