1. A method for moderating live streaming, comprising:
performing preliminary violation moderation on a current live streaming frame in a to-be-moderated live streaming room based on a high-accuracy moderation model and a high-recall moderation model that are cascaded with each other; and
acquiring a target violation score of the current live streaming frame by inputting a first violation score of the current live streaming frame under the high-accuracy moderation model, a second violation score of the current live streaming frame under the high-recall moderation model, and a multi-dimensional behavior feature of the current live streaming frame in the to-be-moderated live streaming room to a pre-constructed behavior moderation model in response to the current live streaming frame passing the preliminary violation moderation;
wherein performing the preliminary violation moderation on the current live streaming frame in the to-be-moderated live streaming room based on the high-accuracy moderation model and the high-recall moderation model that are cascaded with each other comprises:
acquiring the first violation score of the current live streaming frame by inputting the current live streaming frame in the to-be-moderated live streaming room to a pre-constructed high-accuracy moderation model; and
acquiring the second violation score of the current live streaming frame by continuously inputting the current live streaming frame to a pre-constructed high-recall moderation model in response to the first violation score failing to exceed a predetermined accuracy violation threshold;
wherein the current live streaming frame is determined to pass the preliminary violation moderation in response to the first violation score of the current live streaming frame failing to exceed the predetermined accuracy violation threshold and the second violation score of the current live streaming frame failing to exceed a predetermined recall violation threshold.
