A review of research on multimodal knowledge graphs in agriculture

In recent years, knowledge graphs have made great progress in the field of agriculture. However, the traditional knowledge graph construction is mainly based on the single modality of text, but in the actual production of agriculture, it is often difficult to accurately describe the real data scene by using the single-modal data to construct knowledge graphs, thus increasing the limitations of the use of knowledge graphs. The article provides a detailed introduction to the basic concepts of multimodal knowledge graphs and the core technologies. For the application of multimodal knowledge graph in agriculture, the article focuses on summarizing the research on the application of knowledge graph in agricultural intelligent question and answer, crop monitoring, agricultural product recommendation and other fields in agriculture. It also looks forward to and analyses the challenges of constructing multimodal knowledge graph in agriculture and the prospect of multimodal knowledge graph in the field of agriculture.
