Are there examples of AI systems that use grammatical rules in order to recognize commands in natural language?
For example, is there a program, when given the instruction (either by speech or by text) in the form of "Open file-1", will attempt to understand the command as consisting the parts "open" and "file-1", then respond according to how each part is classified?
The focus here is the fact that these kind of instructions are processed with built-in rules of grammar, rather than the rules being learned through observation of data.
