Research on the system of national scientific information resources discovery
service based on semantic association
〇a*
ZENG Jianxun & DING Qiujing〇
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.
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.
