abstract="In this article we propose the possibility to increase the level of security during football (soccer) matches due to analysis of data that are placed on the social networks of these events visitors. We considered different ways to recognize emotions from photographs to trace the changes in the level of emotions in the photos depending on whether these pictures were taken during the game with fights in the stands or during normal games. We tested this assumption and our hypothesis has been partially confirmed. The software solution for emotion recognition from Microsoft Oxford showed that the level of emotional anger is noticeably higher in the photographs taken during the match with fights. In addition, other curious results were obtained, including an analysis of the key of the comments left by events visitors' photos.<p /> <p>Language: en</p>",
