Detecting nearly duplicated records in location datasets
The quality of a local search engine, such as Google and Bing Maps, heavily relies on its geographic datasets. Typically, these datasets are obtained from multiple sources, e.g., different vendors or public yellow-page websites.

Three key features consisting of name similarity, address s...
