Construction method and reasoning device of international maritime collision avoidance rule knowledge graph

Abstract

The invention discloses a construction method of an international maritime collision avoidance rule knowledge graph and a reasoning device. The method comprises the following steps: extracting international maritime collision avoidance rule knowledge; identifying entities and relationships in international maritime collision avoidance rule knowledge, and constructing a rule ontology; storing the constructed rule ontology to form a collision avoidance rule knowledge graph; and realizing automatic reasoning of rule knowledge according to the collision avoidance rule knowledge graph. According to the method, visual expression of international marine collision avoidance rule knowledge can be realized, and the collision avoidance rule knowledge is comprehensively sorted by utilizing a knowledge graph technology, so that a reference basis is provided for an intelligent ship collision avoidance algorithm; and a set of automatic reasoning device based on rule knowledge is constructed according to the collision avoidance rule knowledge graph, so that water traffic object recognition, meeting scene judgment and collision avoidance behavior guidance conforming to rules can be realized.

Description

technical field [0001] The invention belongs to the field of international maritime collision avoidance, and in particular relates to a construction method and a reasoning device for a knowledge map of international maritime collision avoidance rules. Background technique [0002] In recent years, with the development of the computer industry, the application requirements of intelligent ships are also increasing. In the research process of autonomous collision avoidance by intelligent ships, the importance of rules has become more and more prominent. At present, the expert system based on collision avoidance rules is a relatively mature application of current rules in ship intelligence. The advantage of expert knowledge base is knowledge coverage. Comprehensive, the inference engine and the knowledge base are independent and synergistic, but there is no good solution for dealing with real-time data and non-deterministic problems. SUMMARY OF THE INVENTION [0003] Aiming a...
