[OSGeo-Discuss] Search engines and spatial context...

[Gary Lang]

The spatial context they *do* use for sure is a really smart set of
text-parsing address-extraction algorithms. This is what gmail uses to
generate localized advertising and links to Google Maps, for example.

They have also licensed patents and maybe some code from a company that
does derives location from IP addresses reasonably accurately,
regardless of IP registration data.

That's what I'd like to find out, been thinking about this for years.
Virtually everything is spatial so:

  1) do engines look for non-explicit spatial context
  2) do they leverage explicit spatial context (e.g. document metadata
or actual spatial data formats)
  3) do they even deal with new stuff like GeoRSS

I would assume that Google and others do at least some of this, but
perhaps not. Wouldn't it be sweet to have georeferenced document index
(GeoIndex) and a GeoSpider to build it. The Alexandria Digital Library
has definitly operated in that space but seemingly with more traditional
spatial information. I'm curious about regular old web pages, sensor
feeds, news stories and such.

Interesting. Do you mean that googlebot now reads this sort of metadata?

Hi folks: Does anyone know of documents that define the extent that
spatial context (e.g. place names, area codes, addresses) are exploited
by major search engines?
