The invention relates to a live broadcast interaction method and device, a computer readable storage medium and computer equipment, and the method comprises the steps: receiving a gift giving requestinitiated by an audience terminal, the gift giving request carrying a live broadcast video stream identification; acquiring live video data corresponding to the live video stream identifier, extracting an anchor portrait area in the live video data, and sending the extracted anchor portrait area to an audience terminal; receiving an interactive processing result sent by the audience terminal, theinteractive processing result being obtained by the audience terminal through interactive processing based on the anchor portrait area, the interactive processing result carrying a gift identifier andgift position information corresponding to the gift identifier; and based on the gift position information, performing superposition processing on the gift corresponding to the gift identifier and the live video data to obtain a synthesized video stream, and sending the synthesized video stream to the audience terminal. According to the scheme provided by the invention, audiences can participatein the gift making process, so that the interaction degree between the audiences and an anchor is improved.

The invention discloses an identification method and an identification device for live multi-media files. The method includes the steps of: obtaining current feature information of the live multi-media file according to the real-time data flow of the input live multi-media file; positioning a multi-media record to be updated in a feature database according to the identification information of the live multi-media file; updating a feature sample in the multi-media record to be updated according to the current feature information of the live multi-media file; receiving an identification request for identifying the target multi-media file, and matching feature information of the target multi-media file included in the identification request with the feature sample in the feature database, to position the multi-media record corresponding to the target multi-media file; obtaining the identification information of the multi-media file corresponding to the target multi-media file. According to the identification method and device, live videos can be identified.

The invention discloses a live shopping interestingness prediction method based on eye movement characteristics and DeepFM. Data processing related to fixation time is carried out on a live video output by an eye tracker. And tracking the live selling goods by using the packaged tracking model. And establishing a tracking frame as a user viewpoint and a target area. On the basis of the obtained eye movement data of the user, a cooperation information graph is introduced, and user behaviors and project knowledge are coded into a unified relation graph through the cooperation information graph; based on a DeepFM architecture, adding a self-attention mechanism on a deep neural network to improve the learning ability of the model for key information; and outputting a result, and judging the precision of the model through a binary cross entropy loss function Loss and an AUC. A model is trained based on historical browsing data (including eye movement data) of a user. A user can predict the interestingness of the user for live broadcast commodities through the model, so that related personnel can adjust a live broadcast strategy, and the user experience in live broadcast is improved.
