1. A method, in a data processing system comprising a processor and a memory, for identifying changes, within a corpus of information, to answers to questions provided within the corpus of information, the method comprising: registering, by the data processing system, a mapping of a first question and a previously provided answer to the first question in a question/answer data structure; receiving, by the data processing system, a transaction referencing the previously provided answer and having an update to the previously provided answer; correlating, by the data processing system, the transaction with the question/answer data structure and updating the question/answer data structure based on the transaction; determining, by the data processing system, whether a strength of the mapping of the first question to the previously provided answer based on the update to the question/answer data structure has fallen equal to or below a predetermined threshold; and propagating, by the data processing system, a change to the previously provided answer throughout the corpus of information in response to the strength of the mapping of the first question falling equal to or below the predetermined threshold.
