中文摘要:
      商业性资源发现系统特别是国外资源发现系统逐步得到市场认可,国内许多图书馆已经引进,但实践应用中存在资源组织揭示层次较浅、服务功能单一等问题。本文基于国家科技信息资源保障需要及国内外资源发现服务现状,提出构建我国的国家科技信息发现服务体系。从文献数据采集、数据统一管理、语义知识组织、系统服务功能、方法工具支撑五个基本方面进行详细论述,重点强调本体、叙词表等知识组织工具在文献资源语义知识组织中的应用,形成语义关联的数据资源体系,促进系统功能从单一资源级别发现服务向引文分析、科研实体识别等知识服务拓展。相关标准规范建立、知识产权管理等也是构建国家科技信息发现服务体系的重要因素。图4。参考文献17。
英文摘要:

    Commercial resources discovery systems,especially Primo and EBSCO Discovery Service which are provided by foreign companies,are being well recognized by the market. Many university libraries in China have introduced discovery systems for unified searching,but the systems still need to be upgraded in terms of resources organization and service functions.Particularly,semantic association should be applied to the architecture of the system of national scientific information resources discovery service.

    Based on the demands of national information guarantee,this paper analyzes the present situation and the challenges of National Science and Technology Library (NSTL for short),and the application of commercial resources discovery systems in Peking University Library,Tsinghua University Library etc. is also introduced and investigated. Currently,most of the university libraries just use the discovery systems for unified retrieval. The system of national scientific information resources discovery service should be architected for the integration of information service,information resources and library systems.The framework of the national scientific information resources discovery service is articulated from 5 aspects of data acquisition,data management,knowledge organization,system services and method support,which is focused on the process and methods of metadata management and semantic association. Finally,the application prospect of the system of national scientific information resources discovery service is described. The system can integrate the service system and business system as a whole to support information resources acquisition,data organization,user management and information service. At the same time,the system is not only for national institutions but also for the cooperative management of all university libraries and academic libraries in China.〖JP.

    This paper studies the construction framework and process of the system of national scientific information resources discovery service at the theoretical level,but the effective operation of the service system depends on the establishment of a unified system of standards and proper handling of intellectual property issues. Meanwhile,the service system should be updated and maintained regularly with the increase of digital resources,the failure of resource link address,the change of bibliographic information,the change of resource format and so on. A full-process resource maintenance system,from copyright negotiation and authorization data acquisition,data integration and fault tracing,should be established to construct a full-text sharing mechanism that is in line with copyright regulations and benefit balance to ensure the sustainability and stability of discovery services. 4 figs. 17 refs.
