Abstract: In general, techniques are described by which to provide constrained natural language processing. A device comprising a processor and a memory may be configured to perform the techniques. The processor may expose a language sub-surface specifying a natural language containment hierarchy defining a grammar for a natural language as a hierarchical arrangement of language sub-surfaces. The processor may also receive the data indicative of the input that conforms with the portion of the language provided by the exposed language sub-surface, and process the data indicative of the input to identify an intent of the user from a plurality of intents associated with the portion of the language. The processor may next execute a process associated with the identified intent to perform an operation. The memory may store the data indicative of the input.
