10. The computer system of claim 7 , wherein the web mining phase further comprises: iteratively: mining digital content for information corresponding to the stored candidate appendix topic; applying textual analysis to the mined digital content to calculate a measure of relevance to the candidate appendix topic; analyzing the mined digital content to identify at least one relevant result from the mined digital content; storing statistically relevant mined digital content as an intermediate result in persistent storage; and applying at least one heuristic to stored statistically relevant result to identify a final appendix topic candidate.
11. The computer system of claim 10 , wherein the at least one heuristic comprises at least one of: the appendix topic is within a pre-determined number of paragraphs from the beginning of the at least one relevant result; the appendix topic is part of a title of the at least one relevant result; and a pre-determined number of entries in decreasing relevance from a list of relevant results.
