CONCEPT NOISE REDUCTION IN DEEP QUESTION ANSWERING SYSTEMS
First Claim
1. A computer program product for a deep question answering system, the computer program product comprising:
- a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code comprising;
computer-readable program code configured to compute a concept score for a first concept in a first case received by the deep question answering system, wherein the concept score is based on a machine learning concept model for the first concept;
computer-readable program code configured to exclude the first concept from consideration when analyzing a candidate answer and an item of supporting evidence to generate a response to the first case when the concept score does not exceed a predefined concept minimum weight threshold; and
computer-readable program code configured to increase a weight applied to the first concept when analyzing the candidate answer and the item of supporting evidence to generate the response to the first case when the concept score exceeds a predefined maximum weight threshold.

Abstract
Method, computer program product, and system to perform an operation for a deep question answering system. The operation begins by computing a concept score for a first concept in a first case received by the deep question answering system, the concept score being based on a machine learning concept model for the first concept. The operation then excludes the first concept from consideration when analyzing a candidate answer and an item of supporting evidence to generate a response to the first case upon determining that the concept score does not exceed a predefined concept minimum weight threshold. The operation then increases a weight applied to the first concept when analyzing the candidate answer and the item of supporting evidence to generate the response to the first case when the concept score exceeds a predefined maximum weight threshold.

9. A system, comprising:
-
one or more computer processors; and a memory containing a program, which, when executed by the one or more computer processors, performs an operation for a deep question answering system, the operation comprising; computing a concept score for a first concept in a first case received by the deep question answering system, wherein the concept score is based on a machine learning concept model for the first concept; excluding the first concept from consideration when analyzing a candidate answer and an item of supporting evidence to generate a response to the first case when the concept score does not exceed a predefined concept minimum weight threshold; and increasing a weight applied to the first concept when analyzing the candidate answer and the item of supporting evidence to generate the response to the first case when the concept score exceeds a predefined maximum weight threshold. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
