ACQUIRING NEW DEFINITIONS OF ENTITIES

Abstract:

Systems, devices, and methods discussed herein acquiring new definitions for entities from natural language queries. User input comprising a natural language expression may be obtained. A definiendum entity and one or more defining predicates may be identified from the natural language expression based at least in part on a predefined logical form template. An ontology may be search to determine whether the definiendum entity has a previously provided definition in the ontology. The defining predicates are converted to a logical form representation and optimized such that executing the optimized representation as a query against a knowledge base generates a number of results within a predefined acceptable range (e.g., meets/exceeds a lower threshold and/or meets/falls under an upper threshold). The optimized representation may then be added to the ontology.
