What software do you use to do the ontology map? I've been looking for
something like this for a project. Actually, I'd like something even
more interactive, like the code behind the Visual Thesaurus <http://www.visualthesaurus.com/
>.

Dear Geowanking Subscriber,
The ECOresearch Network has just released a geotagged news archive
on the
US Presidential Election 2008. The system gathers and annotates
documents
from blogs, environmental organizations, the Fortune 1000 and news
media
from the US, Canada, UK, Australia and New Zealand. Processing these
sites
yields more than 800,000 documents each week.

The tightly coupled interface integrates geographic maps with
information
landscapes, ontology graphs and tag clouds to reveal both
geographical and
semantic relationships. Each visualization is implemented as a Web Map
Service and displayed via OpenLayers.
Besides geotagging the documents, the system identifies (i)
attention by
counting references to a candidate, (ii) sentiment towards a
candidate by
looking for co-occurring positive and negative expressions, (iii)
keywords
reflecting the most important topics associated with a candidate. The
weekly statistics are available at
http://www.ecoresearch.net/election2008.
I look forward to your feedback; please e-mail me if you know of
similar
initiatives or have suggestions for improving the system.
Best regards, Arno Scharl
