摘要： Embodiments of the present disclosure provide a method and apparatus for generating a commentary. The method may include: acquiring at least one news cluster composed of pieces of news generated within a first preset time length, the pieces of news in the news cluster direct to a given news event; determining a target news cluster based on the at least one news cluster; determining, for each piece of news in the target news cluster, a score of being suitable for generating a commentary for the piece of news; and generating, based on a piece of target news, a commentary for the target news cluster, where the piece of target news is a piece of news having a highest score of being suitable for generating a commentary in the target news cluster.

摘要： A method and apparatus for adjusting a parameter are provided. The method may include: acquiring a current value of at least one parameter which is in a process of generating a video corresponding to a commentary of the news cluster based on a news cluster; determining a video evaluation score of the video which is generated based on the news cluster and according to the current value of the at least one parameter; performing feature extraction on the current value of the at least one parameter to obtain a feature representation;inputting the feature representation and the determined video evaluation score into a pre-trained evaluation network to obtain a predicted video evaluation score; inputting the feature representation and the predicted video evaluation score into a pre-trained operation network, to obtain current operation information; and adjusting the current value of the at least one parameter based on the current operation information.
