A method includes: pre-processing initial data of an acquired to-be-analyzed confrontation scenario, to obtain triplet data marked in a graph data structure, inputting the triplet data into a pre-trained analyzing model, to determine a result of analysis on semantic information of the to-be-analyzed confrontation scenario; wherein the analyzing model includes a plurality of operator networks that are provided with execution priorities, wherein the plurality of operator networks are configured for analyzing relations of different types; and the processing result of any one of the operator networks includes: in the relation type corresponding to the operator network, respective true relations of all of the node pairs, and confidences and descriptive values of the true relations; and according to the graph data structure that is updated by using the processing results of all of the operator networks, characterizing the result of analysis on the semantic information of the to-be-analyzed confrontation scenario.

Method and apparatus for semantic analysis on confrontation scenario based on target-attribute-relation

A semantic representation method and system based on an aerial surveillance video, and an electronic device are provided. The semantic representation method includes: taking a pedestrian and a vehicle in the aerial surveillance video as a target for tracking; inputting a coordinate track of the target into a first semantic classifier to output a first semantic result of the target; performing semantic merging on the first semantic result, and inputting an obtained semantic merging result into a second semantic classifier to output a second semantic result of the target; and performing cluster analysis on the first semantic result to obtain a target group of the target, and according to the target group of the target, the obtained scene analysis result and the second semantic result, determining semantics of the aerial surveillance video.
