Information Retrieval in Computing Model

Information Retrieval is a process through which we obtain and present related information from a very large collection of information resources according to user's query. Information Retrieval can vary according to user's wish, it can be an information retrieval for documents, music, pictures, etc. In a classic search model we have a user who has to fulfil a task. And for that to happen that user needs some information and to search the information needed user should make a query based on the information. So that query will act as an input in a search box, and on the basis of that query our information will be retrieved. But it is required that no misconception happens to user which may lead user to believe that the information needed can be wrong. And if that happens it may lead to improper formation of the query, meaning the query formed on the basis of information can be wrong thus resulting in a wrong result through information retrieval. So it is important for us to pay proper attention to every step that is going to take place during information retrieval. This paper presents a basic IR model and describes how an information retrieval is done following user's query. This paper also addresses how Information Retrieval and Data Retrieval are two different things and are often confused to be one.
