摘要
个性化服务将成为数字化信息服务的主流,如何有效提供个性化服务,主要取决信息发现和资源重组的情况。所谓信息发现是以帮助用户从大量信息集合中找到与给定查询请求相关的、恰当数目的信息子集;所谓资源重组是数字资源按相同的学科或专业重新编排,形成镜像数据资源库。信息发现和资源重组是网络发展和数字资源多样性发展的客观要求。本文探讨了信息发现机制和资源重组的模式,它们两者是相辅相成的。
Peronalized service will becone one of the main patterns of digital information service based on discovery of information and reorganization of network resources.The discovery of information is a technique to help users find the appropriate number of information subsets related to the search query in a large information set.Reorganization of information resources is a process to reorganize them according to the types of disciplines or subjects and form a mirror database.Both information discovery and Reorganization of network resources are essential demands of web and information resources development.This paper discusses the mechanism of realizing information discovery and the model of digital resources.
