 abstract={In recent years, there has been a growing interest in dealing with user preferences expressing both positive and negative information in flexible querying of databases. This is what is usually referred to as bipolar querying of databases. Moreover, the positive and negative preferences do not necessarily have to be each other’s complement, what is referred to as heterogeneous bipolarity. Bipolar Satisfaction Degrees have been introduced as a framework, using an independent satisfaction and dissatisfaction degree, to deal with such heterogeneous bipolarity. In this paper, an overview of different ways to aggregate these Bipolar Satisfaction Degrees is given, possibly taking into account weights allowing to make distinctions in relative importance between the different preferences.},
