An information retrieval process begins when a user enters a query into the system. Queries are formal statements of information needs, for example search strings in web search engines. In information retrieval a query does not uniquely identify a single object in the collection. Instead, several objects may match the query, perhaps with different degrees of relevancy.
An object is an entity that is represented by information in a database. User queries are matched against the database information. Depending on the application the data objects may be, for example, text documents, images,[6] audio,[7] mind maps[8] or videos. Often the documents themselves are not kept or stored directly in the IR system, but are instead represented in the system by document surrogates or metadata.
Most IR systems compute a numeric score on how well each object in the database match the query, and rank the objects according to this value. The top ranking objects are then shown to the user. The process may then be iterated if the user wishes to refine the query.[9]
IN REAL TIME SYSTEM THE OUTPUT HAS COME IN QUICK RESPONSE. WHEN THE USER ENTER HIS QUERY THEN THE OUTPUT COMES IN FEW SECONDS. AND IN BATCH PROCESSING SYSTEM THE THE SYSTEM IS NOT DESIGNED FOR QUICK RESPONSE AND THE USER ENTERS HIS QUERY DAY BY DAY IN A PUNCH CARD AND THE RESULT WILL BE SHOWN TO HIM BY SYSTEM IN FEW DAYS DEPENDING UPON THE QUERY.
