-====== Introduction ======
-Ranking is an important concept in modelling our preferences.
-We rank hotels by their quality using one star to five stars;
-we rank baseball teams by their records using pairwise competitions;
-we rank job applicants by their ability using ordered scores.
-In machine learning, the ranking concept
-corresponds to a rich family of important problems,
-which lend themselves to
-a wide range of applications from social science to
-behavioural science to information retrieval.
-For instance, in a Web search system,
-we want the machines to automatically
-rank/order the results of our query based on relevance;
-in an online shopping system,
-we want the machines to automatically
-rank/rate the products based on user evaluations;
-in a music playing system,
-we want the machines to automatically
-rank/recommend the songs based on our personal tastes.
