Information Retrieval


Information retrieval is the retrieval of the best document against a set of document with the help of a query (such as search strings for web search engines)

A document may be:

  • text documents,
  • images,
  • audio,
  • mind maps
  • videos

A Information Retrieval request will retrieve several documents matching the query with different degrees of relevancy where the top ranking document are shown to the user.

Web search engines are the most well known Information retrieval (IR) applications.
