Embodiment Construction

[0051]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0052] In order to solve the problem that the method of using bullet chatting to semantically tag videos in the prior art ignores the consideration of the interaction characteristics of the bullet chatting, and does not consider that the content discussed in the bullet chatting that appears at the current time may be related to the plot corresponding to the adjacent time , but has nothing to do with the plot corresponding to the current time, so the division of ...

Abstract

The embodiment of the invention provides a video semantics labeling method based on a bullet screen. The method includes: obtaining all words in the bullet screen of a target video and corresponding time stamps; averagely dividing the target video into a preset number of time slices; generating an initial topic set, which contains topics corresponding to all the time slices, and an initial plot set, which contains plots corresponding to all the time slices, according to preset probability correspondence relationships of words and the topics and the plots; generating a dictionary vocabulary setand a vocabulary distribution matrix; calculating temporal a priori information of the dictionary vocabulary set; using a preset total probability formula of bullet-screen vocabulary to calculate probability that each piece of the dictionary vocabulary corresponds to each topic and each plot; generating plot-topic distribution matrices of the time slices; merging adjacent similar time slices intoone time slice; determining plots corresponding to all time slices; and labeling the target video. By applying the scheme provided by the embodiment of the invention for video semantics labeling, labeling on video semantics is enabled to be more accurate.

Description

technical field [0001] The present invention relates to the technical field of video tagging, in particular to a bullet chat-based video semantic tagging method, device and electronic equipment. Background technique [0002] Online video occupies a huge amount of traffic on the Internet, and hundreds of videos are uploaded to the global Internet video platform every day, so the management of online video is very important. Video labeling can improve network traffic resource utilization and online video management efficiency, and is a key link in online video management. [0003] Video websites that have emerged in recent years have added a "barrage" function, which enables users to comment in real time on the episodes they are currently watching. Based on this, we can use the rich comment data in the bullet chat to cluster the bullet chat according to the density of the bullet chat, and then get the time slice of this type of bullet chat according to the earliest and latest...
