Information retrieval is the process of finding and retrieving information from a collection of data or documents, typically stored in a computer system or on the internet. It involves the use of search engines or other tools to locate relevant information based on a user’s query or search terms.
Search engines like Google, Bing, and Yahoo are examples of information retrieval systems that use algorithms to search for and present relevant information to users. These systems use a variety of techniques to analyze and rank information based on factors such as keyword frequency, website popularity, and relevance to the user’s query.
Information retrieval is an important aspect of many fields, including academia, business, and government. It is used to find research articles, legal documents, and other relevant information, and to assist with decision making and problem solving.
