This invention discloses a method for studying visual attention mechanisms based on EEG microstates, comprising: collecting EEG signals from subjects while watching videos and preprocessing them; extracting saliency maps from the videos, and extracting statistical features from the perspectives of spatial saliency information in the local temporal domain and spatiotemporal saliency information changes in the global time series, respectively, to obtain sIQR features and tsIQR features; converting the preprocessed EEG signals into EEG topology map sequences and performing spatial clustering to extract EEG microstate templates, determining the number of templates and selecting the final microstate templates, and then backfitting them to the EEG signals to obtain microstate sequences; extracting microstate features and depth features from the microstate sequences, examining the statistical differences between microstate features and sIQR and tsIQR features, constructing decoding models based on microstate features or depth features, and using the decoding models to decode segments and videos respectively to obtain segment labels and video labels.

The application discloses a content generation method, device, storage medium and program product. First, in response to a video playing instruction of target video content, a historical viewing breakpoint moment of the target video content is determined, and viewed video content before the historical viewing breakpoint moment in the target video content is determined. Then, semantic information including a plot script and / or a key frame of the viewed video content is extracted. Finally, a plot abstract of the viewed video content is generated according to the semantic information. Thus, the plot abstract of the viewed video content is generated by using the semantic information of the viewed video content before the historical viewing breakpoint moment in the target video content, so that the user can quickly review the historical video content that has been played and viewed according to the plot abstract at a current viewing starting moment, thereby making it easier for the user to connect the plot of a long video, improving the possibility of breakpoint continuation playing of the long video, and finally improving the completion rate of the long video.
