1. US20190258461 - Machine generation of context-free grammar for intent deduction

A method for generating context-free grammar for intent deduction includes: retrieving, through a compiler, a first template file for a respective actionable intent corresponding to a first task that is to be performed by a machine; parsing the first template file, using the compiler, to identify a first nonterminal variable that refers to a first nonterminal file containing a plurality of first named entity values; and generating, based on a plurality of production rules specified in the first template file, including at least a first production rule that includes the first nonterminal variable, first context-free grammar for the respective actionable intent corresponding to the first task, wherein generating the first context-free grammar for the respective actionable intent corresponding to the first task includes rewriting the first production rule by replacing the first nonterminal variable in the first production rule with the plurality of first named entity values.
