Abstract: Provided is a process of extracting structured chain-store data from chain-store websites, the process including: identifying, via a processor, a store-locator webpage from a store website; querying the store-locator webpage for store locations in a geographic area; detecting a repeating pattern in a document object model (DOM) of a responsive webpage returned by the store website, the repeating pattern containing location information for stores in the geographic area; extracting, from the repeating pattern, location information for the stores in the geographic area; and storing the location information in a business listing repository.
