Efficient computation of combinatorial skyline queries
2013
Information Systems
Current skyline evaluation techniques are mainly to find the outstanding tuples from a large dataset. In this paper, we generalize the concept of skyline query and introduce a novel type of query, the combinatorial skyline query, which is to find the outstanding combinations from all combinations of the given tuples. The past skyline query is a special case of the combinatorial skyline query. This generalized concept is semantically more abundant when used in decision making, market analysis,
