Quoted: Radar Networks is testing a free, Web-based application, called Twine, that may provide some robotic secretarial help in organizing and retrieving documents.

Twine (twine.com) can scan almost any electronic document for the names of people, places, businesses and many other entities that its algorithms recognize.

Then it does something unusual: it automatically tags or marks all of these items in orange and transfers them to an index on the right side of the screen. This index grows with every document you view, as the program adds subjects that it can recognize or infer from their context.
