Information Retrieval

Information Retrieval (IR) is the process of obtaining information system resources that are relevant to an information need from a collection of those resources. It involves the identification, organization, and access of data stored in various formats, including text, images, and multimedia. The objective of information retrieval is to find and return the most pertinent information based on user queries, often utilizing algorithms and data structures to index and search the content. IR systems can be found in search engines, digital libraries, and databases, enabling users to locate specific information efficiently.
