Claim:
A computer-implemented method for evaluating the market value of items, the method comprising: receiving, by a computer, one or more product specification data sets that identify at least one item that is defined by two or more parameters, or a plurality of items that differ in accordance with at least one parameter; and for at least one item identified in a received product specification data set: obtaining, from one or more databases, a plurality of transaction data sets comprised of previously exposed transaction data between buyers and sellers, wherein the transaction data represents market reference price data of a particular period of time, and wherein the transaction data sets are responsive to the at least one item identified in the product specification data set; adapting the market reference price data by applying one or more pre-defined rules, variables, or criteria operably associated with the item, a parameter of the item, and/or the one or more databases, to the market reference price data, whereby the plurality of transaction data sets are transformed into normalized market price data sets; and using the normalized market price data sets: calculating a market value for the at least one item in the product specification data set; and communicating the calculated market value for the at least one item in the product specification data set to at least one output.
