Scientific and technological resource integration system based on multi-source database

Abstract

The invention discloses a scientific and technological resource integration system based on a multi-source database. The system comprises an acquisition layer, a processing layer, a presentation layer and the multi-source database. The acquisition layer comprises a metadata acquisition module and a metadata cleaning module and is used for receiving scientific and technological resource metadata of a plurality of data sources, storing the multi-source heterogeneous scientific and technological resource metadata into a unified storage format and cleaning the data; the processing layer comprises an intermediate mode module, a mode matching module, a mode mapping module and a data fusion module, and is used for mapping the heterogeneous scientific and technological resource metadata into a unified semantic structure; the presentation layer comprises a data query engine and a standardized output module and is used for outputting the scientific and technological resource metadata into a specific standard form; and the multi-source database comprises multiple databases for storing the scientific and technological resource metadata, is connected with the acquisition layer, the processing layer and the presentation layer, and is used for centrally storing scientific and technological resources from different sources.

Description

technical field [0001] The invention relates to a scientific and technological resource integration system based on a multi-source database, belonging to the technical field of data integration. Background technique [0002] Science and technology resources are the resources needed to engage in science and technology services and activities, including professional science and technology resources and business science and technology resources. The sharing of scientific and technological resources is conducive to stimulating various innovative applications, realizing the efficient dissemination of scientific and technological resources, promoting the cooperation of R&D personnel from different institutions, different fields and even different countries, avoiding the situation of "information islands", and promoting the progress of science and technology. and industrial development are of great significance. [0003] The integration of scientific and technological resources re...

Problems solved by technology

From the perspective of management objects, the data of scientific and technological resources has the characteristics of high dimensionality, heterogeneity, and fast generation speed. The data cannot be automatically transmitted, and the degree of data association and sharing is low.

With the continuous accumulation of scientific and technological resources, the amount of data owned by various industries shows an exponential increase trend, which is prone to problems such as outdated resources, duplication and waste.
