Local Authorities: Address matching and cleansing

Address matching and cleansing

Despite being the source of address updates and the allocation of UPRNs, local authorities are still faced with the challenge of ensuring other users and systems align their address records to the gazetteer, to ensure consistency across the whole organisation. This linking of systems through accurate address data is critical for efficiency, enabling improved delivery of services and more accurate billing.

Tagging with UPRN & geo coordinates

If you’re already using our LLPG/LSG gazetteer, iManage, our matching and cleansing solution, iMatch, will match against that. If not, then we’d match against AddressBase Premium. Either way, it uses the Unique Property Reference Numbers (UPRNs) to match and cleanse the data, allocating any UPRNs that are missing from the source dataset. By allocating the geo coordinates, it allows any department’s data to be viewed spatially.

Its simple interface is easy to configure and effortless to use, showing the matching status of each record that’s processed.

Automated and interactive address matching

Our solution can facilitate both automated address matching, and interactive matching when a more manual approach is needed. You can tailor the automated address matching by choosing:

  • which fields from the source system to use against the relevant part of the LLPG/LSG gazetteer or AddressBase Premium address
  • which phrases within an address to ignore, eg ‘Ltd’
  • which addresses to ignore during the matching process, eg ponds or street furniture.

This maximises achieving an automatic match and results in less time and effort spent in manual address matching. As it is rare that one set of matching criteria will cater for every address in your data set, you can implement multiple matching runs against the data, each with its own set of matching requirements.

Premium matching at 50 million records / 10 hours

Our newly developed iMatch Advanced is an additional capability that will deliver matching at ultimate speed. Developed for a project with national address coverage, it’s capable of matching 50 million addresses in 10 hours, achieving very high levels of matching depending on the quality of data provided.

This ultimate speed is achieved by eliminating any user interface and uses multiple servers to parallel process the matching. This is the product for any large scale, organisation-wide matching needs.

Manually matching residual data

With the remaining unmatched records, iMatch will show in-depth detail on potential matches so you can make an informed choice. This could include:

  • any parent or child properties (especially useful for blocks of flats)
  • its status, ie whether it’s in use
  • other properties in close proximity
  • a map showing the location (tailored to your preference, ie Google Maps, Open Street Maps or OS Maps).

You just choose the potential match and then accept, ignore, reject or log any issues found.  This enables complete control over the quality of data on an address by address basis.

Post-matching export

Once a match is complete, simply export the results of the match back to the source system for address cleansing. The match results will contain the UPRN from the match, the matched BS7666 address and the original address from the source system.

Integrated or stand alone

Our address matching and cleansing solution can be implemented as a standalone solution or can be integrated with our LLPG / LSG gazetteers. As an integrated solution, the automation between solutions will provide greater efficiency, but either way, after matching and cleansing, you’ll be confident your address data is of the highest quality data.
