摘要: This paper deals with database preference queries based on the skyline paradigm, which aim at retrieving tuples non Paretodominated by any other. We propose different ways to fuzzify such in order make them more flexible, increase their discrimination power, drastic or tolerant. In particular, some of these extensions it possible reduce risk getting many incomparable tuples, even when number dimensions is high.
