摘　　要：本文针对现在各类信息资源库的大量存在,且重复度高、不易管理,导致检索的查准率和查全率较低的现状,提出了根据领域特点对信息资源进行检索的技术,通过自动对资源进行分类,将各类信息资源单独进行管理,形成领域库、资源库及其管理平台的资源管理架构,动态调整资源分类,以此为多种不同领域资源库提供信息检索和信息资源服务。There are all kinds of information repositories, which has high repeat degree and ditficult to management, leading to the current lower precision and recall. In this paper, a retrieval technology for information resources is proposed, according to domain characteristics. By classifying the resources automatically, lots of information resources are managed individually, to form resource management architecture of domain bases, resource bases, and management platform. The resource classification adjusted dynamically provides information retrieval and information service to different resource bases.
