Abstract

A computer-implemented system, method and program product generates answers to questions in an input query text string. The method includes determining, by a programmed processor unit, a lexical answer type (LAT) string associated with an input query; automatically obtaining a candidate answer string to the input query from a data corpus; mapping the query LAT string to a first type string in a structured resource; mapping the candidate answer string to a second type string in the structured resource; and determining if the first type string and the second type string are disjointed; and scoring the candidate answer string based on the determination of the types being disjointed wherein the structured resource includes a semantic database providing ontological content.

First claim

What is claimed is:

1. A computer-implemented method for automatically generating answers to questions comprising:
receiving an input query;
determining a lexical answer type (LAT) for the input query;
receiving a candidate answer for the input query;
matching the candidate answer to a first instance in an ontology;
matching the first instance to a first instance type in the ontology;
matching the LAT to a second instance type in the ontology;
identifying one or more l…
