Design And Implementation Of Science And Technology Resource Integration System Based On Knowledge Graph

In the field of scientific and technological services,scientific and technological resources often include papers,patents,scientific and technological achievements,experts,institutions and other fields.Existing technology resource service platforms usually only contain part of the field or part of the data in the field.And the format and content of data between different platforms are often very different,so that users often encounter great difficulties in obtaining knowledge across platforms,so a comprehensive integration of scientific and technological resources is needed in the field of scientific and technological service resources The system organizes related scientific and technological resources to facilitate the user's acquisition of relevant knowledge..In recent years,knowledge graphs have become a hotspot in computer science research.It expresses and displays various entities and concepts that exist in the real world and the relationships between them through the display of graphs.With the development of big data technology,knowledge graph has been applied in many fields such as intelligent question answering,semantic search,and recommendation system.Constructing a knowledge graph in the field of highly specialized scientific and technological resources can not only integrate the data between different platforms,but also display the scientific and technological resource data in the platform well.This paper studies the existing knowledge graph construction scheme and the knowledge organization and display method of the science and technology resource platform,and analyzes its shortcomings.Then it proposes the design scheme of the science and technology resource integration system based on the knowledge graph,from the acquisition and organization of science and technology resources.The four aspects of storage,the construction of knowledge graph,and the integration plan of scientific and technological resources are used to realize the integration system of scientific and technological resources based on knowledge graph.The specific research work of this paper is as follows:1)Design and implement a scientific and technological resource pool.Specifically,it includes multi-platform data acquisition methods,unified integration of the organizational form of scientific and technological resource data obtained in different platforms,and according to the structure of the data,they are stored in different databases for storage and management.And through a knowledge acquisition method based on query depth based on keyword iterative query combined with entity's remote supervision to acquire new knowledge more comprehensively and extensively.This provides data resources for the integration of cross-platform technology resources,and through the construction of resource pools,explores the necessity and means of technology resource pool construction in the case of multiple data sources and big data.2)Designed and implemented a knowledge graph in the field of science and technology resources.The specific work includes designing and implementing a scientific and technological resource knowledge graph construction scheme based on the entire process of scientific and technological resources through the research on the existing knowledge graph construction scheme,and implementing various aspects of knowledge graph construction to study in Related big data technologies required in the process of constructing knowledge graphs,such as entity classification,entity extraction,entity fusion,etc.,provide relevant reference value for the entire process of knowledge graph construction by exploring related technical means based on knowledge graphs in the field of scientific and technological resources.3)The integration of scientific and technological resources based on the knowledge map of the scientific and technological resources:through the entity fusion technology,different entities of cross-platform organizations are merged and expanded to construct a complete knowledge map of the scientific and technological resources.To provide a certain reference to the construction plan of the cross-platform,multi-organization technology resource system.
