Abstract: Provided is a system for detecting a video semantic interval. The system includes a communication module configured to receive a video and a query sentence, memory in which a program for outputting a semantic interval proposal from the video and the query sentence is stored, and a processor configured to execute the program stored in the memory. By executing the program, the processor outputs a semantic interval proposal having start timing and end timing, which is matched with the query sentence within the video, over a pre-trained video semantic interval detection network based on boundary refinements as the results of the detection of the semantic interval proposal, and outputs a semantic interval proposal having a variable boundary through the refinements of a predetermined semantic interval proposal.
