This paper attempts to analyze and bound the utility of various structured and unstructured resources in Question Answering, independent of a specific sys- tem or component. We quantify the degree to which gazetteers, web resources, encyclopedia, web doc- uments and web-based query expansion can help Question Answering in general and specific ques- tion types in particular. Depending on which re- sources are used, the QA task may shift from com- plex answer-finding mechanisms to simpler data ex- traction methods followed by answer re-mapping in local documents.
