A method for retrieving teleplay content, comprising: generating basic summary information corresponding to each teleplay based on basic information of entities of each teleplay; generating episode summary information corresponding to each episode of each teleplay based on episode data of each episode of each teleplay, in which the episode summary information comprises a line summary, a video summary and a plot summary of an episode; establishing a teleplay graph database based on the basic summary information corresponding to each teleplay and the episode summary information corresponding to each episode; and feeding a playing portal for a target episode of a target teleplay corresponding to teleplay search information back to a user based on the teleplay graph database; wherein generating the episode summary information corresponding to each episode of each teleplay based on the episode teleplay data of each episode of each teleplay comprises: obtaining video stream information corresponding to each episode of each teleplay, and extracting target image features for video frames contained in the video stream information; obtaining video content information corresponding to each episode of each teleplay by analyzing the target image features; and generating the episode summary information corresponding to each episode of each teleplay based on the video content information; wherein extracting the target image features for video frames contained in the video stream information comprises: dividing the video stream information into a plurality of video stream information segments; extracting candidate image features for all video frames contained in each video stream information segment from the plurality of video stream information segments; and merging the candidate image features for all the video stream information segments to generate the target image features for the video stream information. generating basic summary information corresponding to each teleplay based on basic information of entities of each teleplay;
