INFORMATION RETRIEVAL Meaning and
Definition
-
Information Retrieval is a process of accessing and obtaining relevant information from a large collection of data or documents in a systematic manner. It involves searching, sorting, and retrieving relevant information to meet specific information needs. It is commonly used in computer science and library science to facilitate efficient and effective access to information.
The primary goal of information retrieval is to provide users with the most relevant and accurate information based on their specific query or information request. This typically involves the use of search engines, databases, and other information retrieval systems. It is a multidisciplinary field that combines techniques from computer science, linguistics, mathematics, and cognitive psychology.
The process of information retrieval typically starts with a user inputting a query or search terms into a search engine or a database. The system then retrieves relevant information based on the query, using various algorithms and techniques such as keyword matching, ranking, indexing, and natural language processing. The retrieved information is then presented to the user in a ranked order of relevance.
Information retrieval is essential in various domains, including web search, e-commerce, digital libraries, bioinformatics, and enterprise information management. It plays a crucial role in enabling users to quickly find and access the information they need, thereby saving time and effort. Continuous advancements in information retrieval techniques and technologies aim to improve the accuracy, efficiency, and user experience of retrieving relevant information.

Etymology of INFORMATION RETRIEVAL
The term "Information Retrieval" is a combination of two words: "information" and "retrieval".
1. Information:
The word "information" comes from the Latin word "informatio", which means "concept, idea, knowledge". It is derived from the verb "informare", meaning "to give form to" or "to shape". In the Middle Ages, "information" referred to the act of instruction or teaching.
2. Retrieval:
The word "retrieval" comes from the Latin word "retrahere", which means "to draw back" or "to fetch". It combines the prefix "re-" (indicating repetition) with the verb "trahere", meaning "to pull, to draw".
Therefore, "information retrieval" combines the concept of obtaining or obtaining knowledge ("information") with the action of bringing it back or fetching it ("retrieval").
