Network live broadcast monitoring method and device and data processing method

The embodiment of the invention provides a network live broadcast monitoring method and device and a data processing method. The monitoring method comprises the steps of determining whether obtained interaction information of a target live broadcast room meets a preset suspected risk condition or not; if yes, selecting at least one video frame from the live video of the target live broadcast roomas a suspected risk frame according to the interaction information; and performing live broadcast risk analysis on the target live broadcast room according to the suspected risk frame to obtain a riskmonitoring result. According to the invention, firstly, a suspected risk live video is identified based on interactive information, and then live broadcast risk analysis is performed on video framesrelated to the interactive information in the live broadcast video; by introducing interactive information of a target live broadcast room, due to the fact that the recognition efficiency of the interaction information is high,
