An example method includes identifying an expression represented as a natural language input for validation by a parser. Each of the phrases in the expression are iteratively converted into a set of tokens by determining whether a current phrase matches a pre-defined token associated with a known grammar rule, and, in response to determining that the current phrase matches a pre-defined token, generating a token for the current phrase for use in validating the expression. If the current phrase does not match a pre-defined token, the unrecognized string of characters is compared to a plurality of dynamic tokens included in an external pool of tokens to generate a generic token of an identified type. The dynamic token is replaced with the generic token and can be used to validate the expression."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Dynamic tokens for an expression parser","description":"The disclosure generally describes computer-implemented methods, software, and systems for enabling dynamic tokens in an expression parser.
