Intro To The Calais Web Service @ OpenCalais.com

Introducing the Calais Web service (4.0)
A Thomson Reuters initiative designed to power next generation publishing solutions
A free API that anyone can use at www.OpenCalais.com
The fastest way to categorize & metatag the people, places, companies, facts and events in your content
An easy way to connect to the open data sources in the Linked Data Cloud , including Wikipedia, DBPedia, Shopping.com, the Internet Movie Database (IMDB) and more

Why? Tagging text is costly and time-consuming
We help in areas where:
The economics don’t support metadata creation
The value of metadata is potentially high
The value of aggregated metadata is potentially extremely high
Seconds Years Seconds Years Tweets Blogs News Scient. Pubs Great Novels Latency Shelf Life

Enhance: Enrich your content with open data from Wikipedia, the Internet Movie Database (IMDB), Shopping.com and more.
Engage: Optimize your user experience, increase engagement and drive repeat visits with topic pages, personalized filtering and real-time alerts.

ClearForest has received sufficient shareholder approval to complete the transaction, which is expected to close in approximately 30 days, subject to customary closing conditions. The financial terms were not disclosed. Reuters plans to retain and continue to work with the existing management team and their highly skilled workforces in the US and Israel. It also plans to continue to support existing products and customers. Reuters believes that search will be a pivotal element to the future of how financial information is sourced and consumed. As part of its drive into this space, Reuters has created a new strategic group and appointed Gerry Campbell, who will oversee the integration of ClearForest and drive this innovation. <Product>Text Analytic Solution </Product> <Company>ClearForest Ltd.</Company> <Company>Reuters</Company> <Country>United States</Country> <Country>Israel</Country> <Company>Reuters</Company> <Person>Gerry Campbell</Person> <ManagementChange offset="2789" length="92"> <Person>Gerry Campbell</Person> <Company>Reuters</Company> <Action>Enters</Position> </ManagementChange> Text markup by Calais <Topic>M&A</Topic>

Quick online demo
Copy and paste the text of a business news article into the viewer here: http://viewer.opencalais.com and press submit. The article is sent to the Calais engine which tags the content and returns it, marked-up.
The tags appear on the left hand rail, and you can click on the plus (+) sign to see the tags expand. (Note that the Calais Viewer is not the Calais service. It is merely a demonstration of how the service works.)
Since we are now on Calais 4.0, you can also use the viewer to see the Linked Data assets related to the tags Calais returns.
For example, here is the Calais summary page for IBM: http://d.opencalais.com/er/company/ralg-tr1r/9e3f6c34-aa6b-3a3b-b221-a07aa7933633.html
And here is the summary page for IBM in DBPedia (the Wikipedia translated into computer language): http://dbpedia.org/page/IBM
