An information retrieval system can help users to retrieve documents relevant to the users' queries. In recent years, some researchers used averaging operators (i.e., Infinite-One operators, Waller-Kraft operators, P-Norm operators and GMA operators) to handle ''AND'' and ''OR'' operations of users' fuzzy queries for fuzzy information retrieval, but they still have some drawbacks, e.g., sometimes query results do not coincide with the intuition of the human being. In this paper, we present new averaging operators, called weighted power-mean averaging (WPMA) operators, based on the weighted power mean for dealing with fuzzy information retrieval to overcome the drawbacks of the existing methods. Furthermore, we also extend the proposed WPMA operators into the extended WPMA operators to handle weighted fuzzy queries for fuzzy information retrieval. The proposed WPMA operators are more flexible and more intelligent than the existing averaging operators to handle users' fuzzy queries for fuzzy information retrieval.
