Problems solved by technology

However, due to the wide range of material characteristics, each piece of material data is relatively independent, and there is a lack of correlation among data items such as material properties, various performance indicators, and applications, resulting in cumbersome retrieval work when users are looking for information such as alternative materials. , thus, it is necessary to study a knowledge map analysis method for material data

Abstract

The invention relates to the technical field of data processing, and aims to provide a knowledge graph analysis method and system for material data, electronic equipment and a medium. The method comprises the following steps: acquiring original material data, and performing entity relationship recognition processing on the original material data to obtain a material knowledge graph; whether a query instruction and to-be-queried information corresponding to the query instruction are received or not is judged in real time, if yes, entity recognition is conducted on the to-be-queried information, and a to-be-detected entity corresponding to the to-be-queried information is obtained; and finally, performing multi-layer cascade visual output on the relationship between the to-be-detected entity and the related entities in the material knowledge graph, the relationship among all the related entities, the related entities and the to-be-detected entity. According to the method, the problem of association and integration of material data knowledge is solved, and a user can be helped to quickly select related materials meeting performance requirements.

Description

technical field [0001] The present invention relates to the technical field of data processing, in particular to a method, system, electronic equipment and medium for analyzing knowledge graphs for material data. Background technique [0002] Knowledge map is called knowledge domain visualization or knowledge domain mapping map in the library and information industry. , construct, map and display knowledge and their interconnections. Based on the knowledge map, complex knowledge fields can be displayed through data mining, information processing, knowledge measurement and graphic drawing, revealing the dynamic development law of the knowledge field, and providing practical and valuable references for subject research. [0003] However, in the process of using the prior art, the inventors found that there are at least the following problems in the prior art: [0004] In the prior art, a knowledge map is constructed for material data. However, due to the wide range of mater...
