Abstract:
1. A method for concept-based search, performed by computing hardware and programmable memory, comprising: retrieving a first unit of natural language discourse from a first record of a first database; parsing the first unit of natural language discourse into a first parse structure that represents sub-units, of the first unit of natural language discourse, by nodes; adding a first concept-value pair, that indicates a first reference to a first pinnacle concept and a first reference level to the first pinnacle concept, to at least one node of the first parse structure, wherein the addition of the first concept-value pair is determined, at least in part, by identifying an occurrence of a first linguistic feature from a first set of linguistic features and the first set of linguistic features is approximately complete with respect to the first pinnacle concept; determining the first unit of natural language discourse as asserting, with respect to a second pinnacle concept, a second reference at a second reference level, wherein the second reference level is determined as a function of a concept-value pair that indicates a reference to the first pinnacle concept; determining a first snippet from the first unit of natural language discourse and the first record; and including the first snippet in a second database if the second reference level is sufficient in relation to a threshold.
