Abstract:
1. A method for detecting trends in clustered business listings, the method comprising: determining, using a processor, a last date that a last attribute value of a business listing has changed; determining, using a processor, whether a number of data providers supplying the last attribute value has decreased by at least a first predetermined percentage since the last date the last attribute value changed; determining, using a processor, whether a number of data providers that have stopped supplying the last attribute value since the last date the attribute value changed is greater than a number of data providers that have begun supplying the last attribute value after the last date the last attribute value changed; determining, using a processor, whether a number of data providers supplying a new attribute value increases by a second predetermined percentage since the last date the last attribute value changed; and determining, using a processor, whether a third predetermined percentage of the number of data providers that have stopped supplying the last attribute value since the last date the attribute value changed have begun supplying the new attribute value since the last date the last attribute value has changed.
