A method of identifying potential trades within a database holding details of individuals and items that these individuals are willing to give away,“Haves”, and/or to receive,“Wants”. The database is searched to identify matching Haves and Wants and to define a directed edge linking the each match. An edge weight can be determined for the directed edge defined for each match and, for one of said individuals possessing a Have, identifying potential n-way trades for the individual by identifying a directed edge or directed edges originating at the individual's Have and/or by connecting two or more directed edges including at least a directed edge originating at the individual's Have, where n is an integer greater than 1. A trade weight is determined on the basis of the or each associated link weight and the potential trades ranked according to the respective trade weights. |
