12. A method for prediction of a target slot value of a user goal for command/control of a personal device, comprising: receiving a user input at the personal device, the user input comprises at least one or more of a periodic feature, a contact-specific feature, a predicate-related feature, a time-related feature and a device-related feature, at least the periodic feature and the time-related feature being independent of content that is included in a user input; for each of a set of slot values, applying a generic argument model on the user input by the user device to obtain a probability that the slot value is the target slot value; normalizing the probabilities of the slot values to infer a distribution over the set of slot values; and employing the inferred probability distribution to identify the target slot value.

The method of claim 12 , wherein the probability distribution determined by the argument model is independent of a speech input.
