Claim One:
1. A method implemented by an information handling system that includes a memory and a processor, the method comprising: selecting a question submitted to a question answering (QA) system, wherein the question pertains to a domain specific corpus ingested by the QA system; analyzing data pertaining to a plurality of answers generated by the QA system, wherein the analysis results in a stability characteristic pertaining to each of the plurality of answers, and wherein the analyzing comprises: analyzing one or more characteristics of answer change pertaining to each of the plurality of answers, wherein the analysis results in a plurality of change frequencies pertaining to each of the plurality of answers; and computing, for each of the plurality of answers, a stability score related to the stability characteristic, by combining the plurality of change frequencies; adjusting a confidence value associated with each of the plurality of answers based on the respective answer's stability characteristic; providing one or more of the plurality of answers to a first requestor based on the adjusted confidence values; storing, in a data store accessible by the QA system, a plurality of inference chains that include a change timeframe and the stability score corresponding to each of the answers; receiving a subsequent question submitted to the QA system, wherein the subsequent question is substantially similar to the question and results in one or more of the plurality of answers being retrieved by the QA system; retrieving one or more stored inference chains from the data store, wherein the retrieved inference chains pertain to the one or more answers retrieved by the QA system; and providing the one or more answers retrieved by the QA system and data pertaining to the retrieved inference chains to a second requestor.
