Define the term “Information retrieval”. Discuss the current trends in information retrieval

Information retrieval, often referred to as IR, is the science and practice of searching and retrieving information from various sources, such as databases, documents, web pages, multimedia files, and more. The primary goal of information retrieval is to match a user's information need with relevant documents or resources in an efficient and accurate manner. The process involves several key steps, including document indexing, query processing, relevance ranking, and presenting the results to the user.

Current Trends in Information Retrieval

1. Natural Language Processing (NLP)

Advancements in natural language processing have revolutionized information retrieval. NLP allows systems to understand and interpret human language, enabling more sophisticated and accurate search queries. With the rise of voice-based assistants and conversational interfaces, NLP plays a crucial role in enabling users to interact with IR systems more naturally and intuitively.
