Abstract 数据挖掘实验室
A system receives a search query that includes a set of search terms, determines whether at least one of the search terms corresponds to the name of a geographic area, and determines whether the geographic area corresponds to an unambiguous geographic area when at least one of the search terms corresponds to the name of the geographic area. The system performs a local search, based on one or more of the search terms, to identify documents associated with the geographic area when the geographic area corresponds to an unambiguous geographic area.
The title of this patent application, and the previous one are so similar, that I was concerned they might be duplicates when I uncovered them. The one above attempts to "extract" location information from a query. This next one attempts to "extract" location information from pages being indexed, with confidence scores indicating how likely it is that business information on a page is associated with an address on the same page.

The system determines whether to associate the business information with the address based on the assigned confidence score.
