Changed Answer Notification in a Question and Answer System

摘要

Mechanisms are provided, in a question and answer (QA) system, for monitoring changes in answers to previously submitted questions. A question is received for which an answer is to be generated. A first answer for the question is generated and the question, first answer, and a notification party are registered in a question registration data structure. A second answer to the question is generated, at a later time than when the first answer was generated. A degree of a change in the answer to the question is determined. An answer change notification is transmitted to the notification party based on the degree of the change in the answer to the question.
