Research on Knowledge Service System of Land Big Data Based on Knowledge Graph

In the context of the rapid development of artificial intelligence and big data technology, the efficient use and integration of data are essential. As a tool for information carrying and knowledge reasoning in the context of big data, a knowledge graph helps to improve the utilization of land resources in villages and towns and the accurate supply of knowledge services. To effectively solve services such as land cultivation guidance, business guidance, and policy consultation, a land big data knowledge service system based on a knowledge graph is proposed. The construction framework and content of the land big data knowledge service system are studied from the technical and functional levels and applied to the land knowledge service platform to provide service functions such as intelligent retrieval, online consultation, land purchase and sale, and personalized recommendation. This service system is expected to provide reference and reference for the research, development, and technological innovation of villages and towns in the era of big data.
