Abstract: A computer implemented method maintaining a database including records of one or more supplier system catalogs enabled by multiple buyer systems. The method includes tracking, by the processor, query expressions and corresponding query results generated from the database by a specific buyer system, the query results identifying matches between the query expressions and a set of records of supplier system catalogs enabled and integrated for procurement with the specific buyer system. The method further includes determining, from the query expressions and corresponding query results, the query expressions that satisfy criteria for low match rates and identifying additional matches between the query expressions and at least one unassociated supplier system catalog outside of the set of enabled and integrated supplier system catalogs, the identifying based upon an analysis of community buyer system data. A report is generated based upon the additional matches and transmitted to the specific buyer system.
