Present Significance
The present significance of IE pertains to the growing amount of information available in unstructured form. Tim Berners-Lee, inventor of the world wide web, refers to the existing Internet as the web of documents and advocates that more of the content be made available as a web of data. Until this transpires, the web largely consists of unstructured documents lacking semantic metadata. Knowledge contained within these documents can be made more accessible for machine processing by means of transformation into relational form, or by marking-up with XML tags. An intelligent agent monitoring a news data feed requires IE to transform unstructured data into something that can be reasoned with. A typical application of IE is to scan a set of documents written in a natural language and populate a database with the information extracted.

Famous quotes containing the words present and/or significance:
“Stevenson had noble ideas—as did the young Franklin for that matter. But Stevenson felt that the way to implement them was to present himself as a thoughtful idealist and wait for the world to flock to him. He considered it below him, or wrong, to scramble out among the people and ask them what they wanted. Roosevelt grappled voters to him. Stevenson shied off from them. Some thought him too pure to desire power, though he showed ambition when it mattered.”
—Garry Wills, U.S. historian. Certain Trumpets: The Call of Leaders, ch. 9, Simon & Schuster (1994)
“The hysterical find too much significance in things. The depressed find too little.”
—Mason Cooley (b. 1927)
