Abstract: Methods and systems for media trend identification of content sharing platforms are provided herein. A set of audiovisual embeddings that represent audiovisual features of a media item is obtained. A set of textual embeddings that represent textual features of the media item is obtained. The obtained set of audiovisual embeddings and the obtained set of textual embeddings are provided as an input to an artificial intelligence (AI) model trained to predict whether a respective media item is associated with one or more media trends of a platform based on given embeddings for the media item. One or more outputs of the AI model are obtained. A determination is made, based on the one or more outputs of the AI model, whether the media item is associated with the one or more media trends of the platform.
