Abstract: A method and system, which may be implemented by employing a program, perform method steps of a natural language understanding (NLU) system which include tagging, 200, recognized words of a command input to the NLU system to associate the command with a context, and translating, 300, the command to at least one formal command based on the tagged words. A top ranked formal command is determined, 400, based on scoring of the tagged recognized words and scoring translations of the at least one formal command. Whether the top ranked formal command is accepted is determined by comparing a feature vector of the top ranked formal command to representations of feature vectors stored in an accept model. The top ranked formal command is executed, 500, if accepted and incorrect commands are prevented from execution.
