Ranker

A ranker is a system or algorithm that arranges a list of items based on specific criteria, such as relevance, quality, or importance. For example, search engines use rankers to order results so the most relevant pages appear first. Rankers analyze various factors—like content quality, user interactions, or metrics—and assign scores to each item. These scores determine their position in the list, helping users find the most useful or accurate information quickly. Essentially, a ranker prioritizes items to improve the efficiency and effectiveness of information retrieval or decision-making processes.
