The invention discloses a
knowledge graph reasoning method and
system for
intelligent decision-making of oil and gas field
enterprise management. The method comprises the following steps: constructing a
knowledge graph reasoning problem concept and a framework; the method comprises the following steps: automatically acquiring knowledge data in an oil and gas field, performing
information extraction on the knowledge data, acquiring entities in the knowledge data and a relationship between the entities, constructing a triple
data set, and constructing an oil and gas field decision-making field
knowledge graph through the triple
data set; the method comprises the following steps: generating a relation
inference rule base and a rule confidence probability based on a knowledge
inference model and method of neural
logic programming; a knowledge reasoning model based on a
cognitive map reasoning framework, cross iteration of new knowledge incorporation and a
cognitive map reasoning process are carried out; and integrating prediction results of neural
logic programming and
cognitive map reasoning, and constructing a knowledge map reasoning model for
intelligent decision making of the oil and gas field. According to the method, the structure of neural
logic programming reasoning is supplemented and enhanced through cognitive map reasoning, and efficient reasoning and prediction in the
intelligent decision making process of the oil and gas field are achieved.
