摘要: Preferences are an important natural concept in real life and well-known the database artificial intelligence community. Modeling preferences as strict partial orders closely matches people’s intuition. There many algorithms for evaluation of these orders. In particular some rely on total order or lattice structure constructed by a preference query. This paper provides overview We present several measures different “better-than graphs” give deep insight into preferences. fact, careful analysis underlying graph” enables one to develop efficient computation.
