Among the numerous variables which influence relevance judgment, document presentation order has been attested to be actually influential by many studies. Since this variable is easy to be controlled by automated information retrieval system, it deserves our more attention and discussion. There are three points in this article: (1) to review the literature on "order effects", which is induced by document presentation order; (2) to verify the hypothesis of "hedging effect", which is one kind of order effect, by a two-stage experiment; and (3) to identify the relationship between number of document and hedging effect.
