Target information of a target video needs to be acquired from a video source server. The video server stores therein video source files of target videos, which may include audio, text, and the like.
For one embodiment, when the target information is text information, the format of the text information may be generally defined as (but not limited to) the following format: < video ID, [ < time start t1, text1>, < time start t2, text2>, … … ]. Correspondingly, applying a natural language semantic understanding technology (such as a BERT natural language pre-training model) to carry out semantic segmentation and text summarization on the text information to obtain segmentation points and summary information: < video ID, [ < time T1, summary information Description1>, < time T2, summary information Description2>, … … ] >.
As another embodiment, when the target information is voice information, the step of generating segment information corresponding to the target operation based on the target information includes: performing voice recognition on the voice information to obtain text information corresponding to the voice information; and generating the segmentation information based on the text information.
