What is ranking?

Ranking refers to the process of ordering items or entities based on a specific criterion or set of criteria. It involves assigning a numerical or ordinal value to each item, allowing them to be compared and positioned relative to one another. Ranking algorithms are widely used in various fields, including search engines (to rank search results), recommender systems (to rank products or movies), information retrieval (to rank documents), and machine learning (to rank features or predictions). The goal is typically to present the most relevant, important, or desirable items at the top of the ranked list.
