1. A method for determining semantics of domain queries comprising:

  • receiving an input query string from a remote device via a network connection;

    pre-defining an input grammar data structure specific to a chosen domain, the input grammar data structure comprising tokens identified by semantic identifiers and syntactic identifiers;

    identifying semantic groups of tokens corresponding to the semantic identifiers within the input grammar data structure having syntactic equivalence as signified by the syntactic identifiers;

    assembling each one of the identified semantic groups into a hypernym to obtain a plurality of hypernyms, wherein the hypernym comprises a hypernym data structure including a hypernym identifier combining a corresponding semantic identifier and syntactic identifier of the each one of the identified semantic groups, and tokens of the each one of the identified semantic groups mapped to semantic outputs, wherein at least one of the semantic outputs corresponding to one of the tokens includes a semantic identifier linking to another hypernym;

    providing a list of fields for combination with the plurality of hypernyms, wherein the list of fields comprises text fields for input of names and keywords and custom tokens for input of dates and locations;

    generating a corpus of valid combinations of hypernyms and fields, based on at least some of the plurality of hypernyms and at least some of the list of fields, according to a set of grammatical rules;

    generating a first mapping data structure mapping each valid combination to a partial semantic output by combining the semantic outputs of the hypernym data structure;

    determining semantics of the input query string based on a tokenization of the input query string, the corpus, and the first mapping data structure; and

    transmitting, to the remote device, a communication associated with a meaning of the input query string based on the semantics.
