An organized pool of knowledge or information resources which a user may access to satisfy an information need. One of the essential components of an information retrieval system is its collection or the database. The collection is generally made up of documents of different kinds.

Information retrieval processing. An information retrieval system for collections of unstructured text can be viewed as a set of processing modules, beginning with lexical analysis of documents and leading ultimately to a retrieval process in which user queries are matched against documents. The processes which make up an information retrieval system are referred to as information retrieval operations. In some cases, the end goal is not the retrieval of matching documents from a collection but an auxiliary application, such as document categorization, summarization, or filtering of information from an information stream. While the basic operations in information retrieval systems are similar, there can be considerable variability in the model or details of implementation, making evaluation of information retrieval system effectiveness an important step. Early work in information retrieval began in the s with the recognition that words in

In this paper we investigate some of the most important variants of information retrieval. CLIR deals with submitting queries in one language and retrieving documents in some other language other than query language. MLIR deals with submitting questions in one or more languages and retrieving documents in one or more diverse languages. With increasing globalized economy, the knack to find information in other languages is becoming a necessity.

Information Retrieval Operations

Summary: The technological advancements in computer networks and the substantial reduction of their production costs have caused a massive explosion of digitally stored information. In particular, textual information is becoming increasingly available in electronic form. Finding text documents dealing with a certain topic is not a simple task. Users need tools to sift through non-relevant information and retrieve only pieces of information relevant to their needs.

Generally speaking, information retrieval includes two different levels: the first one is to effectively use information in an already existing information retrieval system, it is external; the second is to address how information is processed within an information retrieval system, it is internal.
