Rice variety selection method and device based on knowledge graph

Abstract

The invention provides a rice variety selection method based on a knowledge graph. The method comprises the following steps: obtaining data related to rice through a search engine query mode and a user behavior collection and evaluation mode, selecting a neo4j database as a non-relational database, and building the rice variety knowledge graph through a semi-automatic method; and executing rice variety selection based on a program developed by the rice variety knowledge graph, wherein the rice variety selection includes rice variety recommendation, rice variety search and rice variety questionand answer operation. The method is suitable for users in multiple scenes and at different levels to select rice varieties, so that rice seed selection is more scientific and authoritative, and the method has accuracy and usability. Furthermore, knowledge reasoning and auxiliary decision making can be achieved in the rice variety selection method based on the knowledge graph, repeated productionof knowledge is avoided, and the utilization efficiency of the knowledge is improved. The invention further provides a rice variety selection device based on the knowledge graph.

Description

technical field [0001] The present disclosure relates to the technical field of computerized agricultural automation, in particular, to a method and device for selecting rice varieties based on knowledge graphs.

However, rice planters still face many difficulties when choosing rice varieties: the rice varieties on the market are uneven, and it is difficult to distinguish between true and false; the choice of varieties is closely related to the local soil, weather, market demand, labor force and mechanization. It is difficult to quantitatively evaluate the information on one thing and lose another; the information on rice varieties on the Internet has multiple sources, heterogeneity, and dispersal, which makes rice growers at a loss; new rice varieties emerge in endlessly, and growers often hear hearsay, so it is difficult to verify the quality of the varieties
