1. A computer implemented method to arbitrate between results to be arbitrated in order to effectuate a desired result, each of said results to be arbitrated obtained by one of a plurality of procedures from observationally derived data, said each of said results to be arbitrated being an alphanumerical code characterizing an address, each of said results to be arbitrated having a representative characteristic, said representative characteristic hereinafter referred to as a type, said method comprising: a. ranking, utilizing a processor and computer usable memory that causes the processor to perform the method, each of the procedures according to confidence on each of said procedures; b. classifying each of the results to be arbitrated, utilizing a processor and computer usable memory that causes the processor to perform the method, according to a level of accuracy at which each of said results to be arbitrated matches a datum from a database of a plurality of databases; c. comparing, utilizing a processor and computer usable memory that causes the processor to perform the method, each of the results to be arbitrated to each other; d. obtaining, utilizing a processor and computer usable memory that causes the processor to perform the method, at least one indicator for each result to be arbitrated, said at least one indicator indicating a degree of success of comparing each of the results to be arbitrated to each other; e. generating rules, utilizing a processor and computer usable memory that causes the processor to perform the method, said rules utilizing as inputs said results to be arbitrated and information derived from said results to be arbitrated; f. selecting at least one of said rules; g. applying, utilizing a processor and computer usable memory that causes the processor to perform the method, said at least one of said rules to the results to be arbitrated and to the at least one indicator for each result to be arbitrated, said at least one of said rules being applied according to an algorithm; h. selecting, utilizing a processor and computer usable memory that causes the processor to perform the method, from application of said at least one of said rules, said desired result, said desired result being one of the results to be arbitrated; said results to be arbitrated being of a same type of result as other said results to be arbitrated.
