| Abstract(in English) | This paper proposes a method to generate metadata automatically for football games using announcer's commentary. Each commentary is classified using SVM based on the characteristics of the its structure. This clustering result expresses information of scene segmentation which shows a sequence of play event. Finally, events and the agent of each event are extracted from each scene. Experimental results using transcription written by human show the precision rate is 86.9% for the important event extraction, the recall rate is 65.4% in the event which can be extracted by human, and the accuracy for extracting agent of each event is 86.8%. |
