Identification and automatic propagation of geo-location associations to un-located documents
Abstract:
Systems and methods are provided for identifying pages that can be authoritatively, to some confidence level or another, associated with a geographic location, and are provided for grouping documents such that authoritative location associations can be propagated from pages with higher location confidence to pages with lower location confidence. Pages might be identified with authoritative indicators, groups of pages identified including at least one addressed page and at least one unaddressed page, wherein an addressed page is a page having a higher confidence level than an unaddressed page, and at least one processing step performed that is location specific. The confidence level assigned to a page as part of the process represents the confidence that the page is associated with an identifiable geographic location.
