Objectives :
The aim of information retrieval is to provide the user with the “best possible'' information from a database. The problem of information retrieval is determining what constitutes the best possible information
for a given user query. A common form of interaction for information
retrieval is for the user query. These are then used by the information
retrieval system to identify information that meets the user’s needs.
For example, in a bibliographic database, a user might be interested in
finding thesis on some topic. The keywords extracted from the query
would be an attempt to delineate that topic, and then used to improve
precision (ensuring that a significant proportion of the items retrieved
are relevant to the user) and recall (ensuring that a significant
proportion of the relevant items are retrieved).
Recommended prior knowledge: algorithmic knowledge, oriented programming language in the web.
