Information retrieval
From Wiki @ Karl Jones dot com
Information retrieval (IR) is the activity of obtaining information resources relevant to an information need from a collection of information resources.
(TO DO: expand, organize, cross-reference, illustrate.)
Description
Searches can be based on metadata or on full-text (or other content-based) 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.
