Why? Tagging text is costly and time-consuming

We help in areas where:– The economics don’t

support metadata creation

<Company>ClearForest Ltd.</Company> Reuters Announced the Acquisition of ClearForest

New York - April 30, 2007

Reuters, the global information company, has entered into an agreement to acquire all of the outstanding shares of ClearForest Ltd., a privately held provider of Text Analytics solutions, whose tagging platform and analytical products allow clients to derive precise business information from huge amounts of textual content.

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.

The Process

Quick online demo1. 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.

2. 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.)

3. 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
