Abstract: A natural language programming system may configure a machine learning (ML) model to translate natural language descriptions into constrained language statements. The constrained language statements may express the natural language descriptions using a constrained subset of natural language. The constrained subset of natural language includes words with unambiguous semantics and with meaning that has a clear and singular interpretation. The constrained language statements with unambiguous semantics enable construction of valid statements in high-level “English-like” executable programming language. With the present system, a user does not need to learn a new programming language but rather learn to constrain their natural language statements to a subset of the natural language (“constrained language”) and to generate executable programs.
