It should be understood that the specific embodiments described herein are only used to explain the present application and are not intended to limit the present application. In addition, the technical features involved in each embodiment of the present application described below can be combined with each other as long as they do not conflict with each other.

In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but optionally includes steps or units that are not listed, or optionally includes other steps or units inherent to these processes, methods, products or devices.

[0061] Figure 1 is a flow chart of a method for aircraft intention recognition based on a knowledge graph provided in an embodiment of the present application. Figure 1 As shown, the present application provides a method for aircraft intention recognition based on knowledge graph, including:

[0062] 101. Acquire knowledge data of aircraft intent, wherein the knowledge data includes entities, relationships, attributes and / or events, process the knowledge data, eliminate contradictions and ambiguities therein, and merge duplicate knowledge data.

[0063] Specifically, based on the visual modeling method, knowledge representation technology can be used to define concepts, attributes and / or rules related to aircraft, clarify the semantic associations between concepts, determine the semantic associations between concepts, attributes and / or rules, and realize the construction of a multi-level domain knowledge system.

[0064] The knowledge data of aircraft intent includes entities, relationships, attributes and / or events, where entities represent entities of target aircraft, relationships include inclusion relationships, relationship value ranges, relationship constraints, etc. between target entity intents, and attributes and / or events are attribute information inherent in the target itself. These attributes can be parameters used for target intent analysis, such as: the aircraft body has maximum speed, minimum speed, cruising speed and cruising altitude, maximum acceleration, maximum deceleration, maximum overload climb, maximum overload dive, etc.

[0065] Through entity recognition, relationship extraction and other knowledge extraction related technologies, knowledge elements such as entities, relationships, attributes, events, etc. are automatically extracted from structured, semi-structured and unstructured data. Entity disambiguation technology and entity linking technology are used to eliminate contradictions and ambiguities between knowledge objects such as entities, attributes, relationships, events, etc. Knowledge merging technology is used to merge duplicate knowledge. Knowledge reasoning, knowledge calculation, knowledge completion and other technologies are used to start from the existing entity relationship data in the knowledge base, and through reasoning and calculation, new association relationships between entities are established, thereby expanding and updating the knowledge network and obtaining processed knowledge data.

[0066] 102. Generate a knowledge graph of target intent based on the processed knowledge data.

[0067] Specifically, the process of constructing a knowledge graph is as follows: Figure 2 As shown, the processed knowledge data is obtained, including basic equipment information data, event text data, situation data and rule data, etc., and knowledge extraction is performed on the knowledge data, including entity extraction, relationship extraction, attribute extraction and time extraction, etc., and knowledge fusion is performed on the data after knowledge extraction, including entity disambiguation, entity linking and knowledge merging, etc. After merging duplicate data, knowledge update is performed, including knowledge calculation, knowledge reasoning and knowledge completion, to obtain the knowledge graph of the target intention.

[0068] 103. Based on the knowledge graph of target intention, obtain the intention data of the target aircraft.

[0069] Specifically, environmental intelligence data is obtained, and a target activity factor association network is constructed based on the target intention knowledge graph and environmental intelligence data, and the target intention knowledge graph is applied, such as Figure 2 As shown, intention recognition and result feedback are performed to obtain the intention recognition result of the target aircraft.

[0070] In the process of applying the target intention knowledge graph, new requirements and new concepts will be fed back to guide the supplement and improvement of the cognitive framework in the target intention field. Based on the intention recognition and result feedback of the target aircraft, combined with the acquisition of new requirements and new concepts, the processed data can be represented by knowledge, and its attributes, concept layers and rules can be defined. Knowledge extraction can be performed again, and the knowledge graph of target intention can be reconstructed based on historical data to achieve continuous recognition of target intention in complex environments.

[0071] In order to facilitate the use of real-time target intent recognition tasks, knowledge graph embedding learning technology can be used to obtain the implicit semantic information of entities and relationships. Each target in the target intent knowledge graph will have other entities connected to it through direct relationships or indirect relationship paths. These relationships mainly include affiliation, inclusion, and collaboration. These entities can be regarded as attributes of the target. Combined with the inherent attribute information and target state information of the target, it can reflect the target's intention tendency to a certain extent. This knowledge information can be utilized through the embedding propagation method.

[0072] The knowledge graph-based aircraft intention recognition method provided in the embodiment of the present application utilizes knowledge graph embedding learning technology to organize multi-source heterogeneous environmental intelligence data through the target intention knowledge graph, integrate and extract information, thereby improving the accuracy and efficiency of intention recognition, making full use of semantic analysis, and improving the reasoning and analysis capabilities of the target intention recognition model, forming a multi-dimensional information understanding capability across time and space, across tasks, and across entities, thereby realizing intelligent recognition of target aircraft intentions in complex environments.
