A good research tool Rated 5 out of 5 stars
Gnosis is an excellent tool for people who do any web-based research - particularly corporate research for investing, competitive analysis, etc. Gnosis is able to take basically any web page (though news articles are best) and automatically analyze them to locate the people, companies, organizations and geographies inside them.
A suggestion.. Incorporate this tool with a web based RSS reader like Sage and you have a great news reading and research toolkit.
