科研发现系统下元数据中心索引库的建设与发展对策

Constructional and Developmental Strategies of Metadata Center Index Database under Scientific Search System

元数据中心索引库是发现系统的核心,其标准元数据的质量和规模决定着发现系统的发现功能,元数据的标准规范是实现元数据索引的关键,仓储技术、关联技术和云计算等是构建元数据索引库的关键技术,通过对元数据索引库建设、特点和问题的研究,为构建功能强大的元数据中心索引库及发现服务系统提供理论依据和发展对策。

Metadata center index database is the core of the search system,and its standard metadata quality and size determine the searching function of search system. Moreover,the metadata standard is the key to realize the metadata index,and the storage technology,correlation technology and cloud computing,etc.,are the key technologies for constructing metadata index database. The study on construction,characteristics and problems of metadata index database will provide theoretical basis and developing strategy for the construction of powerful data center index database and search service system.
