PRIORITIZATION OF SEARCH RESPONSES SYSTEM AND METHOD

摘要

The present invention provides systems and methods for accurately parsing an information retrieval query and for generating accurate results based on the query. Queries are processed as a collection of atomic terminals of one or more search domains. The systems and methods typically implement a lexicon comprising a set of associations between known terminals and the phrase types to which they belong and a grammar comprising a set of deterministic syntax rules for translating a single phrase type of the domain into an ordered set of phrase types of similar expressiveness. Parsing includes separating a query into identifiable terminals of the domain language and comparing a collection of phrase types against the grammar to see if any subset of phrases types can be grouped together and translated into a higher level phrase type. The invention enables generation of a collection of potentially ambiguous semantic phrase types capable of assigning meaning to the uncovered syntactical structure of the query terminals.
