国内外同构聚合检索系统比较研究A Comparative Study on Homogeneous Aggregation Search System at Home and Abroad
宋爽;张国栋;
摘要(Abstract)：
跨库检索系统已经发展到基于元数据收集的同构聚合检索阶段。从产品功能和产品成熟度两方面考虑,选取了国内外五种同构聚合检索系统Summon、Primo、WorldCat Local、百链、书生同构跨库检索系统进行研究。在对各系统的元数据涵盖范围、功能特点等方面进行比较的基础上,总结了目前同构聚合检索系统软件即服务的共同销售模式,并提出系统主要存在的问题:国外系统在国内实施时需要结合对异构数据库的实时检索方式进行检索,而国内系统按需下载的免费元数据质量有待加强。最后对改进同构聚合检索应用效果提出两点建议。
