8. A computer-implemented method of geocoding based on data retrieval, comprising: receiving a query string accompanied by user context information, wherein the user context information includes at least one of: market data, culture data, map view data or user location data, wherein the market data indicates a preferred geographical region, the culture data indicates a language setting, the map view data provides a geographic context of a current user view, and the user location data is based on a physical location of user; parsing the query string into a set of data-retrieval requests by extracting geographical information to generate a list of ranked geographical information using a weighting function and validating an address from the geographical information, wherein each data retrieval request comprises user context information and fields of a valid address, and wherein the set of data-retrieval requests comprises more than one data-retrieval request for execution by geocoders; selecting a plurality of geocoders to which to send the set of data retrieval requests for execution based on specific requirements of each geocoder, wherein the specific requirements of a first geocoder are different from the specific requirements of a second geocoder, and the data retrieval requests sent to the first geocoder are different from the data retrieval requests send to the second geocoder; and using at least one data retrieval request in the set of data retrieval requests to generate a geocoding command specifically for each of the selected plurality of geocoders to consume, wherein the geocoding command of the first geocoder is different from the geocoding command of the second geocoder; aggregating the set of data-retrieval requests; federating the set of data-retrieval requests and generated geocoding commands to the selected plurality of data geocoders for parallel execution, wherein the selected plurality of geocoders return responses, wherein the responses comprise a set of results; merging the responses from the selected data geocoders into a ranked list of results using predetermined scoring and ranking rules; and selecting a set of results from the ranked list of results and returning the set of results for processing.
10. The method of claim 8 , further comprising: applying scoring rules to results in the responses to generate scores; applying weights to the scores; aggregating the scores into a composites score; and assigning the composite score to a result that spawned the composite score.
