Geographical Location Extraction (filed July 3, 2007)
"A geographical location extraction method and tool to infer a likely geographical location from one or more search terms entered as a query by a user on a search engine or the like."
From a quick look it seems to be a process of examining words to determine how likely it is they are geographic and intended as part of a geographic search. I supposed it's yet another way to try to determine location or location of interest, this time without GPS or Wi-FI or TV but using just words.
