Parameters of IRS

Parameters for evaluating an Information Retrieval System (IRS) measure how effectively the system retrieves and presents relevant information to users. Key evaluation factors include recall, precision, response time, user effort, form of presentation, and collection coverage. These parameters help determine system performance, accuracy, usability, and efficiency in meeting user information needs. Evaluation ensures that retrieval systems provide relevant results quickly while minimizing irrelevant information, thereby improving user satisfaction and supporting effective access to knowledge resources in libraries and digital information environments.
