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:
“There is a Restlessness springing from the consciousness of power not fully utilized, which must be present wherever there is unused power of whatever kind. This is the restlessness of the germ within the seed, struggling upward and downward towards its proper life. ... it is a striving full of pain, the cutting of tender flesh by the fetters of the captive as he struggles against their pitilessness.”
—Anna C. Brackett (1836–1911)
“It is necessary not to be Christian to appreciate the beauty and significance of the life of Christ.”
—Henry David Thoreau (1817–1862)
