Embodiment Construction

[0046] The technical content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] In order to solve the problem of difficult global ontology construction of scientific and technological resources, such as figure 1 As shown, the knowledge map-based scientific and technological resource data integration method provided by the embodiment of the present invention includes the following steps:

[0048] Step S1. Obtain scientific and technological resource data and its data attributes.

[0049] Sci-tech resource data includes structured data, semi-structured data and unstructured data.

[0050] Among them, the structured data is the row data, which is stored in the database, and the realized data can be logically expressed in a two-dimensional table structure. For example, enterprise ERP, financial system, medical HIS database, education card, government administrative approval, other co...

Abstract

The invention discloses a scientific and technological resource data integration method and device based on a knowledge graph. The data integration method comprises the following steps: acquiring scientific and technological resource data and data attributes thereof; according to the scientific and technological resource data and the data attributes thereof, setting a scientific and technological resource local ontology and constructing a scientific and technological resource knowledge graph; setting conversion between the science and technology resource knowledge graph and the global mode as a wrapper, and setting a corresponding wrapper for each science and technology resource local body, so that mutual mapping between the global mode and the local mode is realized; and receiving a query request of a user to display a corresponding query result. According to the invention, the science and technology resource knowledge graph is applied to the global mode, the defect that the real-time performance of a data warehouse mode is poor can be overcome, and effective integration of multi-source heterogeneous data is facilitated. Knowledge extraction can be automatically carried out on mass data by utilizing the constructed scientific and technological resource knowledge graph, so that the problem that the global ontology of the scientific and technological resources is difficult to construct is solved.

Description

technical field [0001] The invention relates to a method for integrating scientific and technological resource data based on a knowledge graph, and also relates to a corresponding device for integrating scientific and technological resource data, belonging to the technical field of data processing. Background technique [0002] Scientific and technological resources are the general term for the human, material and financial resources and other soft and hardware elements engaged in scientific and technological activities. Constructing a complete scientific and technological resource platform can effectively integrate scientific and technological resources in various fields and form a unified standard, so that massive scientific and technological resources can be shared, enabling scientific researchers and scientific research projects to use scientific and technological resources more efficiently and effectively Improve the level of scientific and technological services. In r...
