【摘要】：当今社会，信息呈现爆炸性激增的态势，信息方面方便了用户，，另方面海量的信息资源也给用户获取有用、专指的信息带来了难度。Google等网络搜索引擎的出现给图书馆带来了前所未有的冲击与挑战，越来越多的用户不在或很少使用图书馆检索信息资源。图书馆如何利用新兴的技术手段和服务理念更好的整合信息资源，为用户提供方便、快捷获取信息资源的途径，是图书馆工作的重中之重。网络级发现服务系统的诞生，为图书馆整合信息资源提供了新的途径。网络级发现服务系统可以实现对图书馆本地、开放获取以及订购的各种形式的信息资源的站式检索，并且具有分面导航、相关性排序等发现界面的相关特征。网络级发现服务系统代表着数字信息资源整合的未来方向。本文梳理并探讨了与网络级发现系统相关的背景知识，重点分析了网络级发现服务系统的定义、产生背景、系统原理以及整合图书馆信息资源的优势与特点。在收集已有资料的基础上，从系统架构、界面与检索、元数据、系统定价、Web2.0功能等方面详细、全面的对Worldcat Local、Summon、Primo、EBSCO Discovery Service四大网络级发现服务系统进行了比较分析，并且综合评价了四大网络级发现服务系统的优势、特点以及相应的局限。在对四大网络级发现服务系统比较分析的基础上为信息机构选择恰当的网络级发现服务系统提供了相应的建议。
[Abstract]:In today's society, there is an explosive explosion of information. Information is convenient for users, and vast amounts of information resources also provide users with useful information. The appearance of network search engine such as difficulty. Google brings unprecedented impact and challenge to library. More and more users do not use library retrieval information resources. It is the most important task of library work how to use the new technology and service idea to better integrate information resources and provide convenient and quick access to information resources for users. The birth of network-level discovery service system provides a new way for libraries to integrate information resources. Web-level discovery service system can realize the local, open access and order of various forms of information resources of the library site retrieval, and has the features of the surface navigation, correlation ranking and other discovery interface. The network level discovery service system represents the future direction of the integration of digital information resources. This paper combs and discusses the background knowledge related to the network level discovery system, and analyzes the definition, the background, the system principle and the advantages and characteristics of integrating the library information resources in the network level discovery service system. On the basis of collecting the existing data, this paper makes a comparative analysis of the four Web level discovery service systems, including system architecture, interface and retrieval, metadata, system pricing and Web 2.0 functions. The advantages, characteristics and limitations of the four network level discovery service systems are comprehensively evaluated. On the basis of the comparative analysis of the four network level discovery service systems, some suggestions are provided for information organizations to select appropriate network level discovery service systems.
