Abstract

The invention provides a space target knowledge graph construction system. The space target knowledge graph construction system comprises a text information collecting and processing module, a literature information collecting and processing module, a knowledge graph construction module and a knowledge graph display module. The problems that space target information is high in confidentiality, high in specialty, difficult to directly obtain and the like are solved. Space target related information such as news, microblogs and academic periodicals is obtained. A data mining method is adopted, space target information hidden behind massive information is researched, space target attribute information is visually displayed, the mutual relation between space targets is analyzed, two kinds of knowledge maps are integrated by applying a software technology, and a space target knowledge map system is constructed. The crawler and natural language processing technology is used, so that the information collection and processing efficiency is improved. News and microblog data are preprocessed, so that repeated crawling of the news data is avoided, and the reliability of the microblog data participating in knowledge graph construction is improved.

Description

technical field [0001] The present invention relates to the field of knowledge graphs, in particular to a space object knowledge graph construction system. Background technique [0002] As humans entered the space age, the number of space objects increased dramatically. The U.S. Department of Defense has tracked more than 20,000 objects in space (satellites, debris, etc.), and that number is set to increase dramatically as new, more powerful sensors become available that can detect smaller objects. It is an effective way to understand space targets by collecting information about space targets and further making a knowledge map of space targets. The concept of knowledge graph was proposed by GOOGLE in 2012. It aims to describe various entities or concepts and their relationships in the real world, forming a huge semantic network graph. Nodes in the knowledge graph represent entities or concepts, and edges are composed of attributes or relationships. The knowledge map inte...
