Perhaps after an initial geocoding, you could get together with a representative from the organization that provided these data, and show them a list of uncoded addresses. These files could be reexamined to see if any additional information is available which could help resolve this record and allow it to be coded. In this case, the record can be skipped and the next address be subjected to interactive geocoding. In this way, following the steps described here, the entire list of uncoded addresses can be processed and, in most cases, successfully coded.
27 that you can set the sensitivity of the automatic process higher or lower depending on your confidence about the nature of the errors or abbreviations made and any mistakes that may be in the addresses to be coded. The program has a default of 80 for spelling, a minimum match score of 60, and a score of 10 to be considered a candidate. This latter score is for the interactive process that comes after the automatic process has run; more about this below. You can also specify a table of aliases for your street names if you have such information.
In order to proceed, one needs access to a good independent source for geographic information, such as an atlas or an online service like Mapquest. These are necessary additional sources of information that may be more up to date than the address locator database, and they also provide the geocoder with another perspective on the map, streets, and address ranges they are working with. One also needs to keep in mind the goal of the geocoding project. S. Census block groups in order to compute the rate of violence in each block group.
