Techniques for predicting a penal code and modifying an annotation based on the prediction are provided. A sentence describing a scene captured with a video capture device may be received form a video description system. The scene may depict a criminal act. An artificial intelligence bot may identify a penal code that has the highest probability of being associated with the criminal act described by the sentence. The sentence may be modified based on a lexicon associated with the identified penal code. Feedback indicating if the identification of the penal code was correct may be received. The feedback may be used to train the artificial intelligence bot.
