Returning Related Previously Answered Questions Based on Question Affinity

摘要

Mechanisms are provided, in a Question and Answer (QA) system, for identifying a related previously processed question. A first question is processed by the QA system to generate an answer to the first question and a supporting evidence passage that supports the answer to the first question being a correct answer to the first question. The QA system performs a lookup operation in a question repository based on an identifier of the supporting evidence passage to identify an entry corresponding to a previously processed question, different than the first question, that previously had an answer generated based on the supporting evidence passage. The QA system returns the previously processed question and the answer to the first question to a submitter of the first question.

1. A method, in a Question and Answer (QA) system comprising a processor and a memory, for identifying a related previously processed question, the method comprising:
processing, by the QA system, a first question to generate an answer to the first question and a supporting evidence passage that supports the answer to the first question being a correct answer to the first question; performing, by the QA system, a lookup operation in a question repository based on an identifier of the supporting evidence passage to identify an entry corresponding to a previously processed question, different than the first question, that previously had an answer generated based on the supporting evidence passage; and returning, by the QA system, the previously processed question and the answer to the first question to a submitter of the first question.
