US Patent 11003426 Identification of code for parsing given expressions

A command-processing server provides natural language processing services to applications. The command-processing server stores a set of code blocks, each code block being able to interpret a set of corresponding natural language expressions. The command-processing server accepts natural language expressions and identifies the code blocks that are capable of interpreting those expressions by attempting to parse the natural language expressions using the code blocks. The command-processing server then provides a list of the identified code blocks to the developers, who can then incorporate the code blocks into their applications.
