Semantic movie summarization based on string of IE-RoleNets

Wen Qu, Yifei Zhang, Daling Wang, Shi Feng, Ge Yu
2015 Computational Visual Media  
An IE-RoleNet (interaction and emotion rolenet) models the emotion and interactions of roles in a shot of the movie. The whole movie is represented as a string of IE-RoleNets.  ...  Roles, their emotion, and interactions between them are three key elements for semantic content understanding of movies.  ...  Then affective related features are extracted from music and speech respectively. Most existing approaches to vocal affect recognition use multiple acoustic features.  ...
