1. A method facilitating the identification of similar auctions, comprising: receiving, by one or more computing devices, a set of keywords relating to an auction; identifying a first set of auction objects by searching by the one or more computing devices, based on the set of keywords, a database of auction objects each containing at least one word; receiving, by the one or more computing devices, an identification of a model auction; for at least one auction object in the first set of auction objects, determining, by the one or more computing devices, the probability that the at least one auction object is similar to the model auction based, at least in part, on respective distinctiveness degrees of the keywords in the set of keywords, wherein the distinctive degree, for each keyword, is based in part on an evaluation of the number of auctions in the first set of auction objects and total number of auctions in the first set of auction objects, and respective GeoWeight values of the keywords, wherein the GeoWeight value for each keyword is based on the position of the keyword in the at least one auction object.
