What is Geo-Local Data Evaluation?

Geo-local data evaluation is the process of verifying or enhancing location information. Using a blend of supervised machine learning and active learning, raw location data is transformed into structured data for input into maps and navigation software.

The user experience of any location-based software relies heavily on the quality of the underlying data. Without a solid ground truth, frustrated users will likely abandon the app in favor of a competitor. Lionbridge is a global leader in the development of human annotated geo-local data services. We have access to over 500,000 in-market evaluators who can verify driving and walking directions, find local business information, verify addresses and more. With over 20 years of experience, Lionbridge provides geo-local data solutions to the world’s largest companies.
