Problems solved by technology

However, the above two methods have the following shortcomings: First, the data-driven method can only realize the identification of ship behavior from the data level, but the ship's behavior is constrained by factors such as the navigation environment, and it is difficult to reflect the impact of the ship's surrounding environment on the da...

Abstract

The invention discloses a semantic-based ship behavior dynamic reasoning method and device. The method comprises the steps of ship navigation data arrangement and semantic element extraction; establishing a ship behavior semantic network by utilizing the abstracted and extracted semantic elements, wherein the ship behavior semantic network is used for establishing a semantic relationship among the semantic elements and instantiating to realize structured expression of ship behavior semantics; converting the ship behavior semantic network into a static Bayesian network; the static Bayesian network is endowed with time sequence information and converted into a dynamic Bayesian network; and outputting the ship hiding behavior inferred by the dynamic Bayesian network. According to the method, potential ship behaviors can be inferred from the perspective of human cognition, and decision support is effectively provided for water traffic management.

Description

technical field [0001] The invention belongs to the technical field of ship behavior recognition, and in particular relates to a semantic-based dynamic reasoning method and device for ship behavior. Background technique [0002] The rapid development of global positioning system and automatic ship identification system (AIS) has led to the explosive growth of water traffic data, which has the characteristics of large data volume, fast real-time update, many data types and high degree of fragmentation. It is very difficult to identify and reason about uncertain ship behaviors, and due to the lack of human brain's ability to collect, process and analyze information, it is difficult to have a deeper understanding of ships from a large amount of data, and semantics is a kind of The new mode of knowledge discovery from the perspective of people's expression habits and knowledge understanding habits, from the pure data level to the knowledge level, so identifying, analyzing and ex...
