Abstract

The invention discloses a satellite frequency orbit resource information vector representation method based on cross-entity attribute association, and the method specifically comprises the steps: defining the entity type, entity attribute and entity relationship of satellite communication frequency orbit resource knowledge, and representing the satellite communication frequency orbit resource knowledge in a triple form; representing a satellite communication frequency orbit resource triple as a numerical vector, and defining a loss function of the numerical vector; and establishing cross-entity attribute association characteristics, constructing a multi-objective optimization model, and solving the optimal representation of the satellite communication frequency orbit resource information vector by using a stochastic gradient descent optimization algorithm. According to the method, the satellite frequency orbit resource information with huge data volume, complex association relationship and fuzzy characteristics can be subjected to uniform and efficient numerical expression, and the numerical vector representation can be closer to the true value of the satellite frequency orbit resource information by establishing the cross-entity attribute association characteristic; therefore, the optimal numeralization vector representation suitable for the satellite frequency orbit resource knowledge characteristics is obtained.
