Abstract
Methods, systems, and computer program products for resolving textual numerical queries using natural language processing techniques are provided herein. A computer-implemented method includes determining (i) each variable with a stated numerical value in a textual query and (ii) each variable without a stated numerical value in the query by performing semantic analysis on the query; normalizing each of the stated numerical values corresponding to one or more of the determined variables by automatically converting each of the stated numerical values corresponding to the determined variables to a pre-determined canonical form; mapping (i) all of the determined variables and (ii) the normalized values corresponding to the determined variables to a pre-defined dependency formulae graph; and generating a solution to the query by computing a numerical value for each of the determined variables without a stated numerical value by implementing a graphical model inference mechanism against the graph subsequent to said mapping.
