The computer-implemented method of claim 1 , wherein: determining each parsing initialization comprises replacing, for each annotation, the annotated n-grams of the command input sentence with a non-terminal of the entity type of the annotation service. 5. The computer-implemented method of claim 2 , wherein: each non-terminal type corresponds to a variable for the action; and for each non-terminal type, a semantic yield of a non-terminal of the non-terminal type defines an argument of the variable for the action.
