Effective ingesting data used for answering questions in a question and answer (QA) system

摘要

A mechanism is provided, in a data processing system comprising a processor and a memory configured to implement a question and answer (QA) system, for effectively ingesting data for answering questions in the QA system. A received input question having a set of question characteristics is parsed, which are compared to question characteristics associated with a set of previous questions. Responsive to the set of question characteristics matching the question characteristics associated with one or more previous questions above a related-question predetermined threshold, identification is made as to whether answers to the one or more previous questions were obtained from static information sources or real-time information sources. Responsive to the answers to the one or more previous questions being obtained from the real-time information sources above the predetermined real-time threshold, real-time information sources related to the characteristics of the input question are initially utilized to answer the input question.
