Question Correction and Evaluation Mechanism for a Question Answering System

摘要

Mechanisms are provided in a question answering (QA) system comprising a QA system pipeline that analyzes an input question and generates an answer to the input question, for pre-processing the input question. The mechanisms receive an input question and input the input question to a pre-processor flow path having one or more pre-processors. The one or more pre-processors transform the input question into a transformed question by correcting errors in a formulation of the input question that are determined to be detrimental to efficient and accurate processing of the input question by a QA system pipeline of the QA system. The transformed question is then input to the QA system pipeline of the QA system which processes the transformed question to generate and output an answer to the input question.

主权项

1. A method, in a question answering (QA) system comprising a QA system pipeline that analyzes an input question and generates an answer to the input question, for pre-processing the input question, the method comprising:
receiving, by the QA system, an input question for which an answer is sought by a submitter of the input question; inputting, by the QA system, the input question to a pre-processor flow path comprising at least one pre-processor; transforming, by the at least one pre-processor, the input question into a transformed question by correcting errors in a formulation of the input question that are determined to be detrimental to efficient and accurate processing of the input question by a QA system pipeline of the QA system; inputting the transformed question to the QA system pipeline of the QA system; and processing the transformed question via the QA system pipeline to generate and output at least one answer to the input question.
