Task execution method for multi-model workflow description based on declarative semantics

The invention discloses a task execution method based on declarative semantic multi-model workflow description. In the task execution method provided by the specification, a target task composed of a plurality of sub-tasks and target models required for executing the target task are determined, and different target models are used for executing different sub-tasks; obtaining declarative semantic description of the target task and model information of the target model; each target model is split to obtain a plurality of task units, and different task units are used for executing different task contents under the subtasks; determining a resource demand when each task unit executes the task content, and determining resource allocation information of each task unit according to the resource demand and the declarative semantic description; and executing each task content by adopting each task unit according to the resource allocation information to obtain an execution result of the target task. 本说明书公开了基于声明式语义的多模型工
