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: configuring the data processing system to execute a corpus information source monitoring engine comprising question/answer mapping logic, answer change logic, and previous transaction update logic; executing the corpus information source monitoring engine in the data processing system; registering, by the question/answer mapping logic of the executing corpus information source monitoring engine, a mapping of a first question and a previously provided answer to the first question in a question/answer data structure; receiving, by the answer change logic of the executing corpus information source monitoring engine, a transaction referencing the previously provided answer and having an update to the previously provided answer, wherein the transaction is a user input specifically directed to supporting or refuting the previously provided answer being a correct answer for the first question; correlating, by the question/answer mapping logic, the transaction with the question answer data structure and updating the question/answer data structure at least by updating a measure of strength of the mapping of the first question to the previously provided answer based on the transaction; determining, by the logic of the corpus information source monitoring engine, whether the strength of the mapping of the first question to the previously provided answer has fallen equal to or below a predetermined threshold, at least based on a calculation of the strength of the mapping as a weighted numerical calculation comprising quantified factors corresponding to temporal characteristics of transactions referencing the previously provided answer; and propagating, by the previous transaction update logic of the executing corpus information source monitoring engine, 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, wherein the receiving the transaction referencing the previously provided answer comprises receiving a transaction referencing a second question that has similar features to that of the first question, and wherein the change to the previously provided answer is a different answer from that of the previously provided answer being provided as an answer to the second question.
