Information Retrieval

Information retrieval is the activity of obtaining information resources relevant to an information need from a collection of information resources. Searches can be based on metadata or on full-text indexing.

Automated information retrieval systems are used to reduce what has been called "information overload". Many universities and public libraries use IR systems to provide access to books, journals and other documents. Web search engines are the most visible IR applications.

Famous quotes containing the word information:

    On the breasts of a barmaid in Sale
    Were tattooed the prices of ale;
    And on her behind
    For the sake of the blind
    Was the same information in Braille.
