History
Before the advent of the Internet, there are already several methods of filtering information; for instance, if a government controls and restricts the flow of information, speaking of censorship, although, somewhat in a democratic country it will do to satisfy needs of beneficiaries.
On the other hand, we are going to talk about information filters if we refer to newspaper editors and journalists when they provide a service that selects the most valuable information for their clients, readers of books, magazines, newspapers, radio listeners and viewers TV. This filtering operation is also present in schools and universities where there is a selection of information to provide assistance based on academic criteria to customers of this service, the students. With the advent of the Internet it increases the possibility that anyone can publish low-cost all one wish. In this way, it increases considerably the less useful information and consequently the quality information is disseminated. With this problem, it began to devise new filtering with which we can get the information required for each specific topic to easily and efficiently.

Famous quotes containing the word history:
“Boys forget what their country means by just reading “the land of the free” in history books. Then they get to be men, they forget even more. Liberty’s too precious a thing to be buried in books.”
—Sidney Buchman (1902–1975)
“This is the greatest week in the history of the world since the Creation, because as a result of what happened in this week, the world is bigger, infinitely.”
—Richard M. Nixon (1913–1995)
“It may be well to remember that the highest level of moral aspiration recorded in history was reached by a few ancient Jews—Micah, Isaiah, and the rest—who took no count whatever of what might not happen to them after death. It is not obvious to me why the same point should not by and by be reached by the Gentiles.”
—Thomas Henry Huxley (1825–95)
