The present invention includes model-based processing of linguistic user inputs. In one embodiment, the present invention includes a computer-implemented method comprising receiving linguistic inputs, parsing the linguistic inputs, mapping the linguistic inputs to a formal representation used by a model, applying the formal representation against the model, where the model comprises said formal representation, and where the model specifies relationships between the elements of the formal representation and defines process information, and accessing software resources based on the formal representation of the user input and the relationships and process information in said model.
