James Surowiecki, in The Wisdom of Crowds, proposes that a group of people answering a question emsemble can produce a better answer than an expert answering a question on his or her own. This could be a quirk of people, but the theory says it shouldn't be. Enter this paper, in which the author (without reference to Surowiecki) asks whether a group of computer agents can answer a natural language question better than a single agent. The answer is yes, because different agents operate in different domains and may therefore offer appropriate answers in cases where the domain is ambiguous.
