Editing Information extraction (section)

==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'' <ref>{{cite web|url=http://tomheath.com/papers/bizer-heath-berners-lee-ijswis-linked-data.pdf|title=Linked Data - The Story So Far}}</ref> and advocates that more of the content be made available as a [[semantic web|web of ''data'']].<ref>{{cite web|url=http://www.ted.com/talks/tim_berners_lee_on_the_next_web.html|title=Tim Berners-Lee on the next Web|access-date=2010-03-27|archive-date=2011-04-10|archive-url=https://web.archive.org/web/20110410204952/http://www.ted.com/talks/tim_berners_lee_on_the_next_web.html|url-status=dead}}</ref>  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 database|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.<ref>[[Rohini Kesavan Srihari|R. K. Srihari]], W.
