CoVieW 2018 is a new challenge which aims at simultaneous scene and action recognition for untrimmed video . In the challenge, frame-level video features extracted by pre-trained deep convolutional neural network (CNN) are provided for video-level classification. In this paper, a new approach for the video-level classification method is proposed. The proposed method focuses on the analysis in temporal domain and the temporal attention model is developed. To compensate for the differences in the lengths of various videos, temporal padding method is also developed to unify the lengths of videos. Further, data augmentation is performed to enhance some validation accuracy. Finally, for the train/validation in CoView 2018 dataset we recorded the performance of 95.53% accuracy in the scene and 87.17% accuracy in the action using temporal attention model, nonzero padding and data augmentation. The top-1 hamming score is the standard metric in the CoVieW 2018 challenge and 91.35% is obtained by the proposed method.
