Abstract: A computer-implemented method of detecting price discrepancies over time and providing analysis messages comprises: retrieving a set of price results based on at least one parameter selected from a set of parameters; detecting a pattern in the set of price results; accessing and updating a pattern cause database for identifying at least one predetermined pattern cause based on the detected pattern; analyzing each predetermined pattern cause and associated corrective actions; and generating at least one analysis message containing: the at least predetermined pattern cause and the associated corrective actions.

Abstract: A method of searching for a product or service and presenting the results in a calendar type view; wherein the search is instigated in a request which includes a plurality of parameters, such as a city pair and/or a date, and one or more upsell criteria; the method comprising the steps of: determining via a computer search, results which meet at least one parameter and one or more upsell criteria to thereby determine a flight domain; progressively determining the flight domain via a computer to produce refined results; limiting the number of results in the flight domain based on the at least one parameter, one or more upsell criteria and first one of a plurality of abstraction levels to thereby obtain the refined results, which refined results have lowest prices; and presenting the refined results in a view such as a calendar matrix view.
