摘要
针对目前利用Web页面对数字图书馆进行查询存在的两方面的不足:无法判断从何处和如何精确查找信息,文章提出利用中央服务器在用户和分布式资料库之间充当网关角色,完成用户查询,着重解决如何将不同资料库中信息合并在一起,标准化检索图像的匹配值(数字图书馆所分配的),完成结果合并问题。实验证明,该算法应用于结果合并是可行的。
Nowadays,searching information through the web page has two major drawbacks:we can't determine where to and how to find information accurately.This paper proposes that we can use a centralized server that acts as a gateway between the user and several distributed repositories and accomplish the user query.In this paper we focus on how to fuse retrieved document from different repositories.The proposed approach is based on normalization of matching scores assigned to retrieved images by individual libraries.Experimental results on merging results show that the proposed approach is feasible.
