Description

technical field [0001] The invention relates to the field of knowledge graphs, in particular to a multimodal knowledge graph construction and retrieval system and method. Background technique [0002] Knowledge Graph (Knowledge Graph), known as knowledge domain visualization or knowledge domain mapping map, is a series of various graphs showing the development process and structural relationship of knowledge. , map and display knowledge and the interconnections between them. Knowledge graph is a combination of theories and methods of applied mathematics, graphics, information visualization technology, information science and other disciplines with quantitative citation analysis, co-occurrence analysis and other methods, and uses a visual graph to visualize the core structure of the discipline, Develop modern theories of history, frontier areas, and overall knowledge structures for the purpose of multidisciplinary integration. Knowledge graph, which can provide practical an...
